How to make a plinth on a pile foundation

- a set of piles of various types, on which the building rests. Piles protrude above ground level, therefore an open space is formed under the building.

Socle varieties

There are several ways to equip a pile base:

  • concreting;
  • brickwork;
  • the construction of a fence;
  • installation of plinth panels.

Concreting is carried out by pouring the concrete mixture into the formwork. A shallow trench is dug first.

It is possible to pour a reinforced concrete monolithic tape into the prepared trench, and then lay a brick on it (). This method is good because it does not require strengthening the formwork above ground level.

A fence is a stone or brick jumper, which is mounted between piles. This is usually done in the case of the construction of small light buildings.

Hinged panels are mounted on a crate made of boards or metal. They are often used as a decorative finish () on brickwork or concrete.

Advantages of a hinged plinth

If you are wondering how to make a plinth on a screw pile foundation quickly and inexpensively, pay attention to the advantages of a hinged structure ():

  • cost-effectiveness: installation costs of this design are almost 4 times lower compared to a monolith;
  • high installation speed: two people can complete the full scope of work in 10-12 hours;
  • a high level of protection of the building from dampness: hinged systems are ventilated, so mold does not form in the underground space in wet weather;
  • aesthetics: manufacturers of plinth panels have learned to imitate natural stone and wood in a very believable way.

I would especially like to note the combined panels - three-layer structures made of OSB boards, polyurethane foam insulation and decorative stone.

The latter serves as a decorative finish. The color range of the outer layer is quite extensive.

Technology for arranging a hinged plinth

The installation of the basement of the screw foundation begins with the waterproofing of the piles and the grillage (). It is not recommended to skip this stage, regardless of what material the foundation elements are made of.

Metal must be protected from corrosion, wood from decay. Appropriate mastics and antiseptics are used for processing.

  1. Guides made of metal or wood are fastened to the piles with self-tapping screws or welding. Experts advise using a 40x20x2 profiled pipe or a board impregnated with an antiseptic for this purpose.
  2. Sand filling is being carried out along the perimeter of the future base of the screw foundation. Its depth must be at least 40 mm.
  3. Panels are hung. If there are no combined panels, a phased mounting of sheet material (asbestos-cement boards, sheet slate, etc.), insulation and a decorative layer is carried out. As a heat insulator, you can use foam, polystyrene foam or polyurethane foam ().

At the final stage, the corners are reduced, additional elements, ebbs, drips and junctions are mounted.
