Testing of building structures

(piles, columns, slabs, walls, foundations and other structures)

  • determination of concrete strength in the construction with the help of non-destructive methods;
  • coring for testing in the laboratory;
  • determination of the presence of reinforcement with the description of its diameter, as well as the thickness of the protective layer;
  • selection of bricks and mortar from masonry structures, brick and mortar testing for compression, determination the brickwork strength.

Testing of construction materials

(concrete, expanded clay concrete, brick, mortar, stone, fixtures)

Determination of the concrete strength, brick, mortar and stone. Samples test of concrete in the cubes.

Concrete and stone testing

  • Determination of concrete strength;
  • Determination of water resistance of concrete;
  • Determination of frost resistance of concrete;
  • Determination of the density of concrete;
  • Determination of concrete moisture;
  • Determination of concrete porosity;
  • Determination of concrete class.

Bricks and mortar testing

  • Determination of the compressive strength;
  • Determination of the bending strength.

Soil, sand and gravel testing

(from the quarry, from the bases of roads, from buildings foundations and structures, from backfilling of foundations and pipelines, from ditches)

Construction laboratory conducts engineering-geological survey of soil pit foundation with the issuance of the Act.

Ultrasonic testing (testing of welds)

  • Visual measurement control of piping connections
  • Visual measurement control of metal compounds
  • Ultrasonic testing of welded joints of structures
  • Flaw detection of T-joints (unilateral, bilateral)
  • Flaw detection of joints
  • Flaw detection of corner joints
  • Ultrasonic testing of welded joints of pipelines

Laboratory supervision for property

In particular, the organization of the laboratory post according to the following activities.

1. Quality control of supplied concrete mix:

    • preparation of samples
    • verification of slump
    • temperature measurement in the days of pouring concrete
    • specimens testing for strength
    • checking the mobility of the concrete mix of one brand.
    • provides storage of samples in the chamber of normal hardening according to State Standard/GOST

2.Determining concrete strength by non-destructive methods;

3.Checking the quality of the supplied gravel, sand;

4.Determining the degree of compaction of the soil and sandy grounds;

5.Ultrasonic testing of welded joints of steel structures, pipelines;

6.Thermal survey.
