Laboratorial proportioning of effective working mixture:
 | collection of samples from repair or construction objects before beginning of works |
| identification of sources of local building materials and industrial wastes |
| proportioning of mixture contents and consumption of stabilizing additives |
| optimization of granulometric composition of working mixture, if required |
| laboratory tests of strength properties of optimal working mixture |
| approval of an optimal working mixture formula |
| working mixture quality control in the working process (every shift) |
Research has shown that strengthening of clayey soils with the POLYBOND® stabilizer increases ultimate compression strength of the specimens at 28 days by 1.5-2 times if compared with reference specimens; and the water resistance index increases up to 0.8. The elasticity modulus of a soil layer strengthened with Polybond reaches 600 MPa and more.
