The appearance in the market of technological materials leads to the use of completely new types of fencing. Thus, the foundation for the fence begins to play an increasing role, because from it in the future will depend the strength of the entire structure. Correctly arranged basis is a guarantee that the fence will last several decades. The economical option does not assume an underground part, but the service life of such a structure is several times less. In addition, some building materials from which the fence is made, initially provide for the presence of any foundation.
One of the most popular today is the ribbon foundation for the fence in the form of a continuous tape of concrete. He proved himself from the best side in the construction of any structures and structures. Its excellent performance and resistance to heavy loads help to protect objects from distortion. The only obstacle may be marshy soils that do not allow the use of such bases. The final parameters will depend on the depth of freezing and the structural features of the structure being erected. Today, both monolithic and prefabricated strip foundation is used, consisting of factory reinforced concrete blocks. Its service life can reach sixty years.
On stable soils, the foundation for the fence can be columnar when the base is arranged under bearing supports. However, in this case, the depth of the deposit is determined by the freezing of the soil. For the construction of columnar analogues at the point of installation of the supports, openings are made for metal pipes that act as the main pillars. Additionally, the reinforcement is made using a wire frame. At the last stage, the holes are poured with concrete.
Also, in some cases, the foundation for the fence is combined, if it consists of heavy materials. That is, with a conventional ribbon base, special column supports are added. For the basement part, a formwork is mandatory. The entire structure is poured with concrete so that no voids are formed in it. The combined elements of the two types of foundations give the structure a high strength and stability. In this regard, the horizontal movements of the soil can not have a destructive effect on the base as a whole.
Reduce the construction time will largely help the foundation for the fence on the screw piles. These elements resemble metal round tubes with blades and a special tip, which allows you to screw the poles into the ground by hand or with the help of mechanical devices. Piles are introduced into the ground until they are at a depth of one and a half meters. After that, the cavity is poured with concrete to ensure good stability. The main advantages of such a basis can be considered economical, high construction speed, the possibility of using screw elements on problem soils.
