Finishing the base of the screw foundation

When building a house with a high grillage, the question will inevitably arise, which finish of the basement of the screw foundation will be most acceptable?

The space between the soil surface and the outside of the floor is best closed to reduce heat loss and give the building a finished look.

What are the options for finishing and what materials can be used, we will tell further.

Even if the heat and waterproofing are carried out with high quality, it is better to close the space under the floor in order to use it for household needs.

If thermal insulation measures have not been taken, the lining of the pile foundation is necessary. Depending on the materials chosen, it is possible to provide a significant reduction in heat loss and get rid of drafts.

It is worth noting that the wrong device for finishing the basement of a pile-screw foundation can have unpleasant consequences.

It is mandatory to leave ventilation vents around the entire perimeter of the cladding to avoid rotting of floor materials and corrosion of piles due to high humidity.

Cladding options

Having a house on piles in the initial data, you can arrange the lining of the basement in 2 ways:

  • hinged panels from various materials;
  • brickwork on a strip foundation.

Before finishing the basement, it should be insulated

In both cases, additional work can be done to insulate the basement of the house.

Commonly used extruded polystyrene foam or polystyrene foam.

The first is much more efficient, more durable and not subject to deformation.

Styrofoam is a cheap building material, does not support combustion and is hydrostatic.

Using heat-insulating panels for arranging a pile-screw foundation, you can immediately perform 2 tasks: insulate and.

Paneling

If it is decided to ennoble the basement on screw piles with hinged panels, first you need to take measurements and calculate the volume for the purchase of the necessary materials.

  1. Installation of lathing to screw piles. The crate can be wooden or metal profile. Fastening the elements of the crate to the piles is required carefully, as this is the basis for further finishing.
  2. Finishing panels are attached to the crate. If the panel has a finished look, then the installation should be done carefully, adjusting the corners.
  3. If necessary, seams are sealed, finishing is carried out, cornices for drainage are installed.

Hanging panel

Facing a columnar foundation with suspended panels is not a difficult process if the crate is done correctly. A few simple tips that will simplify the work of sheathing and increase the life of the finish:

  • when making a crate made of wood, it is worth treating the beam with impregnation to prevent rotting, damage by insects and a fire protection agent;
  • it is better to make a metal frame from a profile pipe 40 * 20 * 2 (it is better to treat the installed profile with an anti-corrosion coating);
  • in terms of the contact of the panels with the ground, it is better to choose natural soil and fill the trenches with sand 0.3-0.4 m deep;
  • with heaving soil, a gap should be left between the soil and the panels, in order to avoid the penetration of insects and snow sweeping, closing the gap with roofing material.

brick cladding

Pile foundation trimmed with bricks will gain additional strength

The brick plinth of a stilt house can be imitated with hinged panels, or it can be made of brick. How to make a plinth on a pile foundation brick? We'll have to build another foundation: a shallow foundation for brickwork. The finished pile foundation receives additional rigidity, increasing the reliability of the entire structure. In this case, the closed cycle of the tape is interrupted by the installed piles.

When performing work on arranging bricks on screw piles, you should:

  • dig a trench around the entire perimeter from pile to pile and carry out waterproofing;
  • lay reinforcement in trenches and pour concrete mortar;
  • perform work on waterproofing the outer part of the foundation tape;
  • lay out or any other laying material (foam block, cinder block), ventilation holes must be arranged in the walls;
  • between the house and the brick base, it is worth mounting a drainage eaves.

If the masonry was made of waterproof bricks, then the work is completed. For more information about brick finishing, see this video:

If ordinary red brick was used, the pile foundation plinth must be protected from moisture by installing plinth siding, finishing panels, or exterior and interior plaster.

Pros and cons of a brick plinth

As already mentioned, the construction of a shallow foundation for a brick base will add additional strength to the entire building. In addition, the plinth, made of brick, is easily combined with the blind area, gives the building a solid look and allows you to make a semi-basement for year-round storage. Foundation work can be done by hand. For details about the basement brick support unit and the cold bridge, see this video:

The main disadvantage of such a lining can be called its high cost. The remaining disadvantages are mainly associated with the unjustified use of such a base due to the natural specifics of the site, namely:

  • on heaving soil, the use of a shallow foundation does not make sense, the masonry is quickly deformed;
  • if the relief of the site has large differences, then the brickwork is too complicated.

Summary comparison table of cladding options

Any option for facing the basement of a house on screw piles is quite possible to do on your own. Everyone can decorate their house with basement siding. At the same time, the absence of a gap between the floor and the ground will give the building a finished look and make it warmer.
