Foundations
We offer the construction of foundations.
-Plate, slab foundation from (leave a request) rubles / m2 (plate 200mm), insulated Finnish plate.
The pile-and-strip foundation from (leave a request) rubles / m. (Rostwerk 500X300). – The pile-and-strip foundation consists of a concrete reinforced grillage (tape) and monolithic bored piles on which it rests, so this foundation combines elements of a strip and pile foundation.
Pile foundation, consisting of bored piles or screw piles.
-Screw foundation. This foundation can be used for construction on water: lake, ocean, swamp, mountainside
-Block foundation.
-The pile-and-strip foundation.
Foundations on bored piles with strip combine the advantages of belt and recessed. Bored piles are installed in rows under all the walls of the future house in the corners of the house and in the intersections of the walls, as well as between them. The number of piles and, respectively, the distance between them depends on the weight of the building. To calculate the required number of piles, you need to know the weight of the whole house, and the bearing capacity of one pile. The strength of a bored pile depends on the brand of concrete from which it is made.
Screw metal piles.
Pile coating – 2 component composition based on epoxy resin and enamel. This compound is an anti-corrosion coating.

What is a Floating Foundation?
A foundation is laid on ground by excavating some amount of soil. After that, a structure is built on it. In case of floating foundation, the weight of structure built on the soil is nearly equal to the total weight of the soil (including water in the soil) excavated from the ground before the construction of structure.
Principle of Floating Foundation
The main principle of floating foundation is to balance the weight of removed soil by a structure of same weight which causes zero settlement to the structure. So, this foundation is also called as balancing raft foundation.
Let’s consider a ground with water table at the top as shown in the above picture. The ground is excavated up to certain depth which is below water table. Now in the next step, a building is constructed which is as same weight as of the removed soil and water.
Even the depth of excavation is below the table the total vertical pressure in the soil below the foundation is unchanged because of its balancing weight. But here one point is to be noted that we cannot build a structure immediately after the excavation.
During the time of construction, the effective vertical pressure under the depth of excavation may slightly increase because of unbalancing weight. So, this type of foundations can also be called as partly compensated foundations instead of fully floating or compensated foundations.
Suitability of Floating Foundations
Floating foundations are desirable for the following types of soils:
- Soils which are having good shear strength but having a problem of large settlements and differential settlements under heavy loads. In which case, floating foundation can reduce the settlement values to greater extent.
- Soils which are having low shear strength and there is no hard layer of soil at reasonable depth. Here also, floating foundation helps to reduce the shear stresses to satisfactory level and hence settlement is prevented.
