Test of soil when backfilling

the Type and composition of the soil is one of the key components of successful construction. Therefore, thorough soil investigation according to numerous criteria and characteristics is a prerequisite before beginning the building process.

Test of soil when backfilling

Soils differ in composition. Identify several basic types – clay, sandy, loamy, rocky. Each of these varieties has its own characteristics. Some of them are ideal for construction, others require individual selection of type of Foundation, and others generally are not suitable for the construction of reliable, large-scale structures.

As already mentioned, geodetic works carried out in different directions. For example, we investigate the composition of soil and its chemical characteristics. But one of the main directions should be an examination of the degree of compaction. To calculate this ratio, you need to hold a testing ground. Testing procedures are performed and at the construction site and in the laboratory.

In the field can perform the sensing of soil static and dynamic ways. But in the laboratory using special instruments studied the density of the soil, its moisture content, degree of filtration, particle size.

a Large part of the testing procedures performed at the initial, pre-project stage. And on the basis of the results already selected options and construction methods, the materials are prepared. However, the tests required during excavation – backfilling of the pit. Naturally, the main and most of the pit reserved for the Foundation, reinforced and poured concrete. However, at the edges of the concrete base is empty space, which in the professional sphere is called the sinuses.

Test soil during backfilling is an actual procedure. Of particular importance acquires the analysis of the degree of density. After all, when filling the aforementioned sinuses filled with soil must be every inch. Otherwise, the presence of voids can lead to deformation and destruction of structures and grounds.

To backfilling was correct, and the tests were performed in accordance with the norms, it is necessary to hold it after flooded basement is well poised and well established, and casts were removed.

One of the issues that arises in the course of the process is choosing the type of soil for backfill. Particularly relevant similar study of the case at the initial stage of surveying work was carried out. You need to study the composition of the soil that is available and was obtained during the excavation of the pit. But if the composition of the soil is not suitable for backfill need to use imported foreign soil.

Also, as already noted, the emphasis on this figure as the density. Need to pick this soil for backfill, which would be good utrambovyvaya and tightly lay without forming voids. In this case no ground shrinkage and deformation of the Foundation.

of Course, each client focuses on practical construction is very good team, and construction materials. But do not forget about quality geological tests. They guarantee successful completion of the construction and long-term usage of facilities. To do this, please contact the engineers-geologists of the company  “the Guild of Engineering”, which will hold a soil testing when filling how to pre-stage and stage backfill.
