Pile foundation with piles - evaluate
This type of foundation is suitable for constructing structures on weak soils, such as peat soils or swampy terrain, that is, it is used when a layer of incompressible soil is at a depth not suitable for other types of foundation.
Pile-and-tape foundation
To the advantages of include the possibility of its use in areas with a strong slope and weak ground. A relatively small number of necessary materials and their low cost also distinguish this type of foundation among others. When using it, you can use a concrete mixture prepared independently.
Belt foundation with piles has its .First, its arrangement requires complicated calculations. Error in them is expensive, because the building can simply crack. Secondly, such a foundation can not be laid for structures with heavy walls and large overall weight. Thirdly, the technology of constructing this foundation does not provide for the creation of a basement or a basement floor.

Pile foundation - varieties of structures
This building element has several varieties: a strip foundation on screw and on bored piles. A screw pile is a metal pipe with blades of screw thread. In fact, this is a huge screw that is screwed into the ground.
Screw thread increases the bearing area and rigidity of the attachment in the ground. You can screw such a pile both with the use of special equipment, and manually. Before installation, it must be carefully painted to extend its service life.
Tape foundation on bored piles requires already drilled wells. The concrete mix is poured directly into the well, when the earth is solid and does not crumble. If the well is drilled in loose ground or in soil with high humidity, then it is necessary to cope with it.
For this purpose, an asbestos-cement, steel or cardboard pipe, which in combination will play the role of waterproofing, is suitable. It is inserted into the well, and already concrete is poured into it. This type of foundation is most suitable for construction on its own.
Tape foundation on stilts - how to make this design yourself?
By equipping the with the self-pile foundation, it is more advisable to use circular piles, because with a common construction drill only a round bore can be made. Supports of rectangular cross section will require the use of special equipment.
Scheme of pile foundation
The wells are drilled both at the corners of the tape and along the perimeter at a distance of 1.5-2 m from each other. The depth of the wells can be from 1.5 to 3 m. The role of the sand pillow can not be overestimated, because it protects the entire structure from mechanical impact. A sand pillow 30 cm high falls asleep under each pile.
After that, the formwork must be installed on both sides of the tape. It should be properly reinforced, so that it is not squeezed out by the concrete mixture being poured. After the formwork is completed, complete reinforcement of the piles and tape should be carried out in a single structure. If possible, the rods of the armature must be integral. They are tied together with a wire or welded.
After the reinforcement, it is possible to fill a strip foundation on piles. First piles are poured themselves, and then the tape, and between these procedures should pass as little as possible. The device of such a foundation must be approached with all seriousness, since an unprofessional approach to this work will bring some losses.
