The pile foundation is fundamentally different from a monolithic or tape structure. Its peculiarity lies in the fact that the pile heads are not recessed into the ground, but are the above-ground part of the foundation. And no matter what type of piles was used - the essence of this does not change. To give the facade a pleasant appearance, the space that forms between the ground surface and the base of the house must be closed. We will tell you about how the lining of the pile foundation is done with our own hands in this article.
If the house is built of brick or block, the pile field is usually crowned with a reinforced concrete grillage. The basis for wooden and frame-panel houses is a steel channel, or timber. So:
This kind of foundation is chosen if the soil on which it is planned to put the house is heaving, or, conversely, too dense. Or the area is subject to seasonal flooding from time to time.
But the main selection criterion is the price of the structure, which significantly saves the construction budget. Indeed, in this case, you can save not only on the foundation itself (see), but also on the construction of basement walls by arranging the so-called false base.
Its essence lies in the fact that the basement space is masked by some kind of sheet material. Facing the foundation should close not only the opening between the house and the ground, but also the visible part of the grillage.
Cladding types
If we take into account that not only residential buildings, but also various outbuildings are built on screw piles: baths, sheds, temporary huts, then closing the space under them can be done in the simplest and cheapest way. So:
For example, asbestos-cement sheets, or as we used to call them “flat slate”, are used for the device of a false base. Fasten it with special bolts and slate nails. Of course, the appearance of such a "base" will be unpresentable, which, in principle, is normal for a barn.
But the facing of the pile-screw foundation of a residential building should be beautiful, and flat slate can also help us with this. After all, it is an excellent basis for mounting tiles. And you can take a tile even cement-sand, even clinker, even from natural stone.
In this way, you will get an excellent appearance of the basement of the house. A similar finish can be made on the surface of cement-bonded particle boards. This material is even stronger than slate, lighter and easier to install. DSP can be cut and sawn, drilled, fastened with nails and screws.
They do not have such a property as fragility inherent in asbestos-cement sheets. In the photo below, we show a diagram of the device of the false base and. And if you still watch the video, then you can easily cope with the task.
OSB boards can also be used as a base for tiles. Unlike DSP, the binder in the production of this material is polymer resins. This fact makes the tiles impervious to moisture, they do not even need to be primed before tiling. OSB boards are so durable that they are also used structurally, for example, in frame-panel houses.
If you want to simplify the process of facing a pile foundation as much as possible, while obtaining a high-quality imitation of stone or brick, it is easiest to use fiber cement or polypropylene basement panels. And in general, you can use any kind of siding and composite panels.
Alternatively, you can use to create a decorative basement wall. Half-brick laying is quite enough for this.
In cases where the above-ground part of the pile foundation is only 30-40 cm, this type of cladding is practically not used. Whether it's a matter when in the space between the base of the house and the ground, you can equip a full-fledged basement.
In this case, brick walls are made not decorative, but ordinary, one and a half bricks, and even with insulation. There is comprehensive information on this topic on our website, and now we are talking about the device of a false base.
Paneling
Since any panels are mounted on a frame, it is necessary to start with its installation. In the simplest version, a 40 * 100 board, or 40 * 40 bars, is used for its installation. The size of the elements of the crate, and the number of its belts will depend on the height of the plinth and the weight of the panels:
First, the board is laid out along the base of the future basement, and markup is applied to them with a marker opposite each pile. According to these marks, drilling for fasteners will be carried out.
The elements of the crate will be fixed with bolts 8 * 55 mm, it can be a little longer. To make the fixation as strong as possible, it is necessary to use metal perforated tape during installation.
The bolts are inserted into the holes, a tape is put on one of them, and a washer on top. Then the nut is baited. The length of the piece of tape must correspond to the pitch of the fasteners.
The board is pressed against the pile, the free end of the tape is brought in, and put on the second bolt. Full tightening of the nuts is made after the position of the elements of the crate is adjusted according to the level.
Protruding corner boards are cut flush with the end of the adjacent board, and connected using metal corners. Further everything is simple.
All panels are equipped with a special fastening edge. They can even be attached to a wooden crate with nails. For free air circulation, it is necessary to make air holes in the casing.
Well, each type of panels is fixed to each other in different ways. It depends on their design. Usually, when buying a product, an instruction is also attached, and no one has problems with installation.
