A fence made from corrugated boarding on a strip foundation is expensive, but reliable
A country house, as a rule, means the presence of some, even a small, piece of land that must be fenced both from neighbors and from the street. And it is desirable that the fence was impenetrable for views, because you, like those who live next to you, have the right to a personal life without looking at it from others. The first thought that arises in many people is a brick wall two people high. But this is nothing more than wastefulness, since it is possible to achieve the reliability of a fence without such radical means, it is enough only to install a fence of profiled sheeting on a ribbon foundation. By the way, this kind of foundation is divided into two types: monolithic and prefabricated, which means that you have a choice.
When speed and price do not matter in priority, it is possible to use the services of contractors and install reinforced concrete blocks with a crane, thus obtaining a prefabricated strip foundation. Such building blocks are produced at the factory, and the life of the fence base obtained with their help rarely exceeds 65 years. The bulk of the work falls on digging a trench to immerse blocks in it. Next, the poles are fixed, fixed with reinforcement belts, covered with blocks and poured with concrete. Cheaper, but requiring much more time - a monolithic tape foundation. It can be obtained by pouring gravel, brick fragments and cobblestones with cement-sand mortar( all this mixture is cobbled together by the armature).However, the technology of manufacturing the foundation for the fence requires a more detailed description.
The foundation for the fence from the profiled sheeting with a one-and-a-half-year guarantee
If the site has already been built, then you already have basic data on the ground, otherwise they need to be obtained: the depth of groundwater, the structure of the soil. After that, making sure that everything is in order and in this place it is possible to install a structure with high sails, the marking begins under the trench for the foundation. The next stage is earthwork itself, we go deep into the earth by 40 centimeters, the width of the trench is not less than 20 centimeters, where the pillars are provided, in the trench the pits are dug to a depth of 40 centimeters. The distance between the poles of the fence from the corrugated board is about 2-2.5 meters .Next - the installation of supports that drop into the pits prepared for them( a roofing felt can be lowered into the recesses in advance), and another 20 centimeters are pushed into the ground. It remains only to tie the poles with belts from the armature, about 10-15 centimeters below the edge of the trench, it is possible to start the reinforcing cage on the whole foundation to increase the strength of the base, the thickness of the rod can vary from 5 to 10 millimeters.
Now, depending on what type of foundation is chosen, monoblocks are laid in the trench, or it is filled with a bit more than half of the gravel interspersed with the crushed brick and broken cobblestone. The backfill is watered and tamped. Two armatures are horizontally welded to previously prepared reinforcement belts so that they do not reach the walls of the moat and its filling by 5 centimeters. Then comes the last stage of preparation of the foundation for the casting - installation of formwork. It is best to use a prefabricated metal, it is easier to work with and remove it is not an example easier. The height of the basement basement can be different, depending on your desire, but as far as possible not lower than 20 centimeters. Accordingly, the height of the formwork should be the same, and even better than 5 centimeters above the planned height of the socle. Pouring of cement-sand mixture is carried out layer by layer, in order to avoid occurrence of voids .When the formwork is filled, we leave our construction for 2 weeks to build strength, watering the surface of the cement on hot days.
The foundation is ready, we remove the formwork and mount the corrugated board
It is not at all necessary to wait for the complete hardening of the foundation, it is enough that the cement hardens slightly to remove the formwork. In its place, between the strip of cement and earthen walls, sand is poured, its granularity does not matter. The supporting structure for the corrugated board is assembled on the supports already when the cement reaches its maximum strength. It is logical that on the site of the installation of the gate with the wicket the basement of the basement should be interrupted, although the underground part has a right to exist. Frame for corrugated board is made by welding from profile pipes with a section of 40x20 mm, then it is fixed to the supports by the same method or bolted connection. Holes for mounting the corrugated board are made simultaneously in the rolled metal product and the lintels so that they coincide.
Determine in advance whether you will use self-tapping screws or rivets for the corrugated board, but it's better to choose the latter, this option will exclude the possibility of dismantling the fence site without your knowledge.
The number of fixing points for the corrugated board, whether it is screws, bolts or rivets, should be sufficient so that each individual section of the fence can withstand gusts of even heavy wind. By the way, for rivets you will need a special tool, self-tapping screws require only a Phillips screwdriver.since the sheets of corrugated board are installed vertically in the enclosure, they need to be lapped over one wave. It is recommended to fasten the fence of the fence closely to the base of the foundation, without a gap, so as to completely protect your site from prying eyes. Above, to smooth the line of the fence, you can install a fence, but, this is at your discretion( you can also pull the barbed wire).
