Fence on screw piles: installation, advantages. DIY fence on screw piles

02.09.2023

Any owner, thinking about installing a fence for his home or property, prioritizes strength, reliability and durability. All these parameters are usually achieved through the use of high-quality base posts for the future fence. Currently, most experienced builders believe that screw piles, which are able to ensure the stability of the structure even in the softest soil, cope best with this task.

Screw piles for fencing can be considered as the most convenient and reliable support for any type of fence, which is formed by a long steel pipe with a screw at the bottom, which penetrates deeply into the soil layers and firmly fixes the structure.

It is appropriate to use this type of fence base for any type of soil, with the exception of rocky. Screw posts for a fence hold the structure so rigidly that their use is justified not only in the construction of fences, but also in the construction of multi-story buildings.

As a rule, pillars of this type are about 2.5-3 meters long, provided that half of the product is hidden underground. In general, the design of such a support can be decomposed into the following elements:

Sharp, smooth tip, on which the screw blade is located - this part must have special strength, since it will have to enter solid ground;
Long steel pipe, which crosses the plant layer of soil, loam and clay;
Heading– part of the pile structure that protrudes above the ground;
Aboveground part– a standard metal pole on which the fence sections will be attached.

Advantages of using screw posts

Screw piles for fences are now often used in the construction of fences, as they have a number of positive qualities, including:

High level of strength, which allows you to effectively resist soil heaving;
Versatility, which manifests itself in the possibility of installation in any type of soil, including frozen ground and areas with a slight slope;
Ease of installation: the structure is screwed into the ground according to the principle of an ordinary self-tapping screw;
Possibility of reuse, what is important when erecting fences around temporary objects - after a certain time they can be removed from the ground and used in another place;
Opportunity for savings provided that the order of material and installation of the fence is carried out through one company;
Speeding up the fence installation process: there is no need to strengthen the soil, since the screw is fixed in its hard layers;

When installing a fence, it is important to take into account the possibility of corrosion of screw supports in the ground, so before installation it is necessary to coat them with special compounds (bitumen or polymer).

Screw-type ones, mounted taking into account all requirements, can ensure a fence service life of at least 50 years.

How to choose screw piles for a fence?

When purchasing screw posts, it is important to pay attention to some important options:

The length of the pile is selected depending on the height of the future fence, taking into account the fact that half of the part will be underground. For example, when erecting a fence of 1.2-1.5 meters, a post 3 meters long will be required;
In weak soil, such as peat, sand or swamp, it is necessary to use thick screw pipes, while in strong soil, thin rods will hold up well;
The sharp tip of the pile must be at least 10 cm long, and the thickness of the screw blade must be at least 8 mm (they will have to drill into hard soil).

Cost of screw fence posts

For many citizens, the determining factor in choosing a fence on screw piles is the price: such a design will ultimately cost 25-30% less than a traditional fence on poles, not to mention saving time and a longer service life.

The price of a screw pile for a fence per piece depends on the thickness of the steel pipe, which, in turn, is selected depending on the type of fence. So you can pay attention to the following prices for one beam of standard length 3 meters:

For installation, you will need pillars with a diameter of 55-57 mm, the cost of each of which is approximately 1200-1300 rubles;
For installation, stronger piles with a diameter of 87-90 mm are needed, the price of which ranges from 1700-1900 rubles;
During construction, piles with a thickness of 100 mm or more are required. The cost of one such design will be 2500 rubles or more.

Turnkey price for installing a fence on screw piles

The price of a turnkey fence on screw piles depends on the material of the fence itself, its height and length, as well as the set of components used, which include:

pillars with caps;
longitudinal logs;
corrugated sheeting, mesh or wooden sheet;
self-tapping screws;
primer, bitumen, paint.

In general, installation of a fence fixed on screw piles includes the following steps:

deepening the support pillars into the ground by 1.2-1.5 meters;
welding to the bases of longitudinal joists;
attaching the fence material to the base using self-tapping screws;
formation of an embankment near pillars of sand and crushed stone.

If you order a turnkey fence on screw piles from a specialized organization, then in general it will be 25-30% cheaper than purchasing materials, tools and installing the fence yourself. Leave the solution to this issue to our specialists and they will quickly and efficiently install a durable fence on your site using screw structures that will serve you for decades.

How to choose and install screw piles for a fence at the dacha

Screw piles are a special design that has several blades at the end. It is this side that screws them into the ground.

Increasingly, this material is used as the main material not only for the foundation, but also for installing fences. The features and installation method will be discussed in the article.

The advantage of screw piles over other supports

Surely everyone has at least the slightest idea of what a pile looks like and what it is intended for. But this is the advantage of screw piles over conventional types - not many people are familiar with this. Therefore, it is worth highlighting several of their noticeable advantages:

a special design that makes it possible to screw in, rather than drive the pile into the ground;
higher reliability;
speed of work execution;
possibility of use in almost any soil conditions (hill, water, slopes, swamp, etc.);
there is no need to level the area;
construction with screw piles can be carried out even in winter;
after screwing, construction can begin immediately;
reuse possible;
maintainability;
do not create vibration when crashing into the ground;
the ability to carry out work manually;
long service life.

Such serious advantages even over the usual concrete foundation force builders to gradually abandon traditional options and gradually switch to screw piles. Thanks to them, there is no need to wait for the solution to harden, which is why work time can be reduced by almost 30%!

But the main thing is that such a list of advantages is not complemented by a high price. On the contrary, it is quite low and the project will be less expensive than even a strip foundation.

Types of screw piles

A screw pile for a fence can be selected according to its type. This criterion includes several of the following categories:

having a cast tip;
galvanized with cast tip;
welded

The first two types of piles are used for heavier structures, and welded ones are usually chosen for building a fence. In addition to the blade, they have a cone, which allows them to better penetrate the ground during installation. The location of the blades is perpendicular, which is very important, since thanks to this, the earth does not loosen when screwed in.

When installing, it is important to take into account the wind load that will be placed on the fence. If it is high, then it is better to give preference to screw piles, suitable for installing heavy structures and having a diameter of at least 76 millimeters.

To avoid corrosion and, accordingly, extend the service life, the welded screw pile is coated with a special compound. By the way, such a pile can not only serve for a long time, but also carry load up to 4 tons! This allows them to be used not only for light fences made of chain-link mesh, but also for those that will be mounted from reinforced concrete slabs.

Corrugated fence on screw piles

Do-it-yourself pile installation

Installation technology has several important rules. Compliance with them, firstly, will improve the quality of the installed fence, and secondly, will protect you from mistakes. First, a test screwing is performed. This is necessary to determine the required length and depth of twisting of the piles. At this stage, the composition of the soil is determined, since installation can be carried out either to a depth of 5 meters or 1 meter. The depth of freezing of the ground is taken into account so that the piles do not bulge later.

As soon as the preparatory work is completed, their installation can begin. During the screwing process, the pile can be easily extended. To do this, it is enough to attach a special coupling to it as soon as the main part is secured. After installation, the remainder of the pile is cut off and sealed using M-150 solution. This process is necessary because it protects against moisture penetration into its cavity and significantly increases the load-bearing capacity.

Screwing the pile

Since not everyone has special equipment for installing a fence made of screw piles, it is worth considering the DIY installation process in more detail:

After marking the territory, the piles can be screwed in manually. In this case, the upper part of the blade should remain on top for now.
Next, a manual lever is constructed, with the help of which further screwing will be carried out. A thin long pipe is enough for this. It is important to take into account that with a length of two meters it will be much easier to twist it.
Additional load can be placed on the pile in case of loose soil. In such a case, it is better to ask another person for help.
It is necessary to ensure that the pile is installed evenly. If the pile deviates by more than 2%, it will need to be pulled out and screwed in again. The same measure will be required if it cannot go deeper than 1.5 meters. This is quite easy to determine, since the metal will begin to deform somewhat due to the force applied to it.
Next, cementation is carried out and the solution is poured inside.
Welding the platform and supporting pillar to the structure. After this, jumpers are also welded to them.
Afterwards, the top of the pile should be treated with a special compound that can protect the metal from external influences. Mastic is well suited for this purpose, but then it is worth priming the surface first.
Fastening the materials that will make up the fence.

The sequence of further work will depend on the size of the pile that is planned to be left above the ground. If this is a pole up to two meters, then the guide lags are installed. If up to 60 cm is left, then installation of fence posts is required.

Installation of guides

When planning the fastening of corrugated sheets, you will need installation of two guides - lower and upper. In this case, there are two possible mounting methods:

welding the guide to the supports;
screwing them in with bolts.

In the latter case, special metal corners are additionally welded to the pile at the point where the guides pass. Pre-drill areas for fastening on them.

Frame for a fence made of screw piles and guides

There may be several guide lags, but their number should not be less than two.

Installation of corrugated sheets

The style of the fence will initially dictate the method of attaching the corrugated board. Usually the installation is carried out parallel to the supporting pillars. It is possible to avoid distortions of the canvas if you initially take accurate measurements.

The panel must be installed at a height of 5 centimeters from the ground. This is necessary, since the corrugated sheet that will be in contact with the ground will very soon become unusable due to the action of moisture on it. Even additional processing agents will not help protect it.

In general, work on installing corrugated sheeting to a fence made of screw piles can be done according to the following sequence:

Determining the height and required lower limit.
Extension along the perimeter at a given height of the construction thread.
Applying the first panel, after which you should ensure that all measures are followed accurately.
Fixing the sheet.
Alignment of other corrugated panels in accordance with the previous one, applying to the joists and fixing.

This stage is the final one and the fence on screw piles is completely ready for use.

In this case, corrugated sheeting can be replaced with any material from which the fence is supposed to be made, even ordinary boards. However, the installation principle will be similar, which means that these instructions will suit almost everyone.

Fencing on stilts made of wood

Since ancient times, people have sought to protect their territory. At a minimum, so that their private home or dacha avoids prying eyes. But fencing also makes it possible to protect yourself and mark the boundaries of your territory. At the same time, we must not forget that it must be of high quality, presentable, strong and have an affordable price. And screw piles, which have already gained popularity both in Europe and the CIS countries, fit all these parameters.

And the main feature of screw piles is that they can be erected in unstable soils without any danger. The supports can be installed on any soil, even in marshy areas, which is undoubtedly a huge advantage of this type of fastening.

What it is?

A screw pile is a metal pile that has a screw cutting blade at the end. Piles are divided according to the type of thread section. There are several types of threads: standard, with blades and combined. Piles with different types of thread differ not only in appearance, but also in what load they can withstand and how long they can last.

Features of choosing screw piles

The strongest and most expensive are screw piles with blades. Basically, they have two blades. Such piles, despite their high cost, are the most popular because they are the most durable and can be placed on any type of soil.

The load-bearing capacity of fastening directly depends on its diameter. The thicker the diameter of the pile, the greater the mass the structure itself can support.

When choosing piles, you need to take into account the features of your future fence.

Piles with a diameter of 57-219 mm are especially popular. A smaller diameter is suitable if you want to build a foundation under a metal mesh or picket fence. The average value is used for a fence made of corrugated board. And the largest diameter is suitable for heavy cladding.

The next criterion for selection is the type of tip. The tip can be either welded or cast. The most durable are piles with cast tips. They are bought infrequently; they are used in the construction of very heavy structures.

So, what you need to know to make the right choice:

soil composition;
the depth of soil freezing in your region;
the material from which the construction will be made.

When purchasing, do not forget to check the quality certificate or product passport. The structures themselves should not have welding seams; the corrosion coating should be applied not by handicraft, but by an industrial method.

Advantages

The most important advantage is the price of the product, since screw piles are not the most expensive on the market, with this material you save approximately 40-60 percent. Another advantage is that one pile can withstand a load of a couple of tons. You can install it yourself, as the process is quite simple.

The construction of such a fence will allow you to avoid unnecessary costs, since when erecting a fence on a strip foundation, you would have to dig a whole trench. And if you wanted to have a columnar foundation, you would need to dig separate holes for each column. And the main obstacle for a conventional fence would be the possibility of running into groundwater - all this does not matter when constructing screw piles.

You also save on pouring the base with concrete. Such pouring is a very difficult, but necessary stage of construction, which no longer allows you to build a fence with your own hands without special skills. All these actions are unnecessary when constructing a fence from screw piles. The only thing that may be required is to tie the products together with a metal profile to strengthen the structure.

The mechanism itself can be installed at any time of the year; it is not for nothing that they are installed even in permafrost conditions, which is undoubtedly a plus. Such a fence can easily stand for more than a century.

Another advantage is simple dismantling and the ability to reinstall the fence in another location.

The installation mechanism is simple, anyone can figure it out, since the piles can be screwed into the ground without special equipment. The time you will spend screwing in one pile is approximately 20-30 minutes.

Preparation of materials

During installation you will need a number of materials and tools. Choose high-quality materials, as this will determine the strength of the structure and the length of time it will serve you.

A number of parameters need to be taken into account:

weight and dimensions of the material from which the fence itself will be made;

You need to purchase:

guides for fastening;
gate posts.

You can also purchase, if you wish, the material that you will need in the future:

chain-link mesh;
forged sections;
brick;
wooden picket fence;
welded mesh with polymer coating;
metallic profile;
concrete spans.

Here you need to focus not only on quality, but also on design. There is a very wide choice on the market - buy what you like. And always pay attention to the wind resistance, height and weight of the product, so that in the future the piles are suitable for this type of fencing.

During installation, as with any type of construction work, there are often some nuances that must be taken into account. Before you start screwing in the fasteners, you need to do a test screwing to determine the possible depth of the structure. This will depend solely on the composition of the soil. If the soil is very strong, then the piles can be immersed to a depth of approximately 1.5 meters.

After this, do not forget to mark the perimeter of your fence, be sure to take into account the presence of underground communications that may pass under your fence so that unpleasant incidents do not happen.

When erecting a structure on moisture-saturated soils, do not forget to lay the foundation below the freezing level of the soil - this is necessary so that during seasonal changes, the fastening does not “pull out”.

The driving of the piles itself can be carried out with the help of specialists (if there is financial opportunity) or independently. To install the piles, you will need two assistants and a special gate (which you can buy or make yourself).

To create such a product, you will need reinforcement (d = 3 cm), which is inserted into a special technological hole. It is recommended to put on pieces of square pipe on both sides, which will act as a lever in the future. The optimal length of such a product will be approximately three meters.

If you start to feel a lot of tension while screwing in, stop. This can damage the metal.
It is better to screw in the piles with three people, so that the third one guides the pile and monitors its direction.
Do not use much force if you encounter some kind of obstacle on the way - you may also deform the material. In this case, it is better to use a drill, but its diameter should be smaller than the pile.
First, you should tighten the corner piles - with this trick you will achieve the evenness of the fence.

You need to calculate the number of piles, taking into account that the step between them should be approximately two and a half meters. Yes, in some cases you can install supports three meters apart, but no more than that. Make a small recess in the places where the piles are installed - it will help you in the future when screwing in. Place pegs in the corners of your area and stretch a thread between them.

You need to carefully adjust the vertical position of the pile in the soil. This is necessary even when installing ordinary poles. Otherwise, a lot of effort will need to be spent on correcting defects and leveling the fence. To achieve an even vertical fit, it is better to use a special tool.

Fence installation

So, we have come to the most crucial moment - screwing in the piles. As written earlier, do not forget to prepare the material, soil surface and invite two assistants. And make sure that the lever you will use to screw in can withstand the load.

Check the markings of the support points and the size of the recess again. Install the side posts (thereby getting used to the installation). Next you can install intermediate piles. And remember that in the future it is no longer possible to correct the verticality of the pile.

After installing all the piles, you need to align the heads with respect to each other (you can use a grinder for this). But the depth should generally be at least one and a half meters.

Next, if you plan to install a heavy fence, use a special solution M-150. You must use it to strengthen the place where the pile exits the ground. And in any case, it is recommended to fill the cavities with concrete mortar to achieve maximum structural strength. Filling will also increase the moisture resistance of the structure. You can fill the above-ground part with a primer and anti-corrosion solution.

One of the main directions of our company is the construction of fences on screw piles. Installation of a fence on screw piles in summer cottages has gained popularity due to its low cost, high reliability and durability. Screw piles for a fence are an ideal solution for installing a fence on almost all types of soil.

Features of installing screw piles for a fence

Screw piles for fence posts can be installed in an unprepared area, next to buildings and growing trees and stumps, in areas with difficult terrain, and on swampy soils. Using a fence kit on screw piles is often the only option for building a reliable and durable fence.

Installing a corrugated fence on screw piles will not cause harm to your site due to the lack of excavation work. You get a clean area with a ready-made fence made of corrugated sheets on screw piles. Screw piles for fences can be easily dismantled if necessary and can be used repeatedly. Fences made of corrugated sheets on screw piles are extremely resistant to being squeezed out by soil, since the pile is screwed below the freezing level.

In our country, screw piles have been used in private and industrial construction for more than 10 years, and every year wooden fences on screw piles are becoming more in demand. The versatility of application, the affordable price of screw piles for a fence and the possibility of installation at any time of the year make screw piles extremely popular among developers. Picket fences on screw piles are only at the beginning of their path to conquering the domestic market and are becoming increasingly widespread.

7 reasons to buy screw piles for a fence in Moscow:

RELIABILITY. Many people choose a fence on screw piles with installation (the price is also affordable) precisely because of its reliability and durability. Even under high load, the service life of screw piles is at least 100 years, and for fences this period is much longer.

This is the main advantage over the classic fence. The screw pile is screwed in below the freezing level (1.7-2.0 m) and is not squeezed out by the soil.

IMMUNITY TO SOIL MOBILITY. The diameter of the blade allows the screw pile to withstand both horizontal and vertical loads, thanks to which the fence will not lose vertical symmetry even on moving soils. This is especially important when constructing a fence made of corrugated sheets, since high windage puts a load on the posts, which over time can topple the entire structure.

VERSATILITY. The installation of a fence on screw piles is possible at any time of the year and on almost any type of soil, except rocky. Screw piles are successfully used in the construction of fences made of any materials: metal, wood, brick, etc.

INSTALLATION TIME. Installation of screw piles for a fence can be done quite quickly and without loss of quality.

ECO-FRIENDLY. When installing a fence on screw piles, there is no need to use equipment or perform earthen and concrete work, so the landscape of your site will not be damaged in any way.

PRICE turnkey installation of a fence on screw piles -acceptable ratio of high quality and availability.

Based on the above facts, it can be understood that the service life of a fence on screw piles is several times longer compared to the traditional method. A fence on screw piles is the best choice if you want to get a high-quality structure with a long service life. Installing a fence on screw piles is quite quick, and it will serve you for many years!

For a fence to last a long time, it requires high-quality supports. For fences made of relatively light materials, for example, corrugated sheets, it is better to use screw piles. They are easy to install, do not require equipment and last a long time. Let's look at step-by-step instructions for installing a fence on screw piles.

Preparation of materials

To install a fence on screw piles you will need a number of materials. They must be of high quality, since the durability and reliability of the structure depends on this. When selecting supports, it is necessary to take into account a number of parameters, including the weight and size of the corrugated sheets, the probable wind load and some others. Will need:

fence screw piles of a combined type with walls of about three and a half millimeters (have smaller blades);
guides for fastening corrugated sheets;
gate posts;
corrugated sheeting 0.5mm thick.

After acquiring all the materials, you should prepare for the process. First of all, find assistant Because it will not be possible to install the piles alone. One person should hold the support, and the second should screw it in.

Installation of a fence on screw piles

The construction of a fence on screw piles begins by marking the site. After the installation locations for the supports have been identified, installation begins directly.

The installation of piles is carried out using nozzles equipped with two handles. They are used to rotate the pile.

To install a fence on screw piles, the distance between them is set at two and a half meters. The supports are buried one and a half meters. Once they are installed, you need to follow the step-by-step instructions for installing a fence on screw piles.

After completing these steps, the fence on screw piles will be ready. You will also need to install a gate or wicket depending on your specific needs. To install a gate made of corrugated sheets, first weld the frame, then attach the corrugated board to it. The resulting structure is mounted on a support.

This type of fence on screw piles is easy to install, relatively inexpensive, but quite reliable.

Features of installation of screw piles

In order for a fence on screw piles to be of high quality and durable, it is very important to pay attention to small details. They only seem unimportant, but in fact they play a significant role.

Firstly, the area for placing the piles must be exactly mark out. Supports located at different distances will not make the fence stronger.

Secondly, guides need to be weld as carefully as possible. They are located at the top, middle and bottom. This placement will give the frame strength.

Thirdly, the distance between the guides should be approximately equal. The bottom one should not be too close to the ground so that the corrugated sheet does not touch the ground. With close contact, it breaks down faster.

Another important detail in creating a fence is the installation gate. When installing fencing made of corrugated sheets, sliding gates can be a convenient option. To install them, you need to perform the following processes. Short piles are screwed in next to the fence. Two of them are enough. They are welded to them channel, and in turn there are rollers attached to it. The door leaf will move along the rollers. Then the trapezoidal structure is installed. A profiled sheet will be attached to it and you will get a gate leaf.

Screw piles for fences - reviews

Screw piles are actively used for the construction of fences, so you can always find people who can give feedback. It must be said that opinions were divided. Some consider screw piles a waste of money and offer more traditional and cheaper support options. But there are other people who just erected a fence on such stilts.

Almost all owners of fences that use screw piles as supports are satisfied with the design. They point to durability such a fence, they say that you don’t have to remember about it, i.e. it serves perfectly without any additional maintenance.

The only negative that can be mentioned in this case is price. The option with screw piles cannot be called budget. However, durability and reliability, coupled with ease of installation, are worth it.

Appearance of the fence

Above, the article describes a fence made of corrugated sheets, for which supports in the form of screw piles were used. But corrugated board is not the only possible option. Let's look at various solutions and make sure that the appearance of the fence can be anything.

Fence from wooden picket fence, which is attached to metal guides. Since the picket fence has less weight and windage, there is no need for a central guide. The design becomes lighter and simpler. The picket fence can be fixed in one layer or in two: outside and inside.
