Pakol Inektsionny V (high-strength microcement) — class B65 injection grout

Other concrete repair materials

The high-strength version of the microcement: at a water/solids ratio of 0.3 the grout reaches 85.0 MPa in compression (B65) and 10.0 MPa in flexure (Btb8.0) after 28 days. It is injected to strengthen foundations, consolidate internal damage in concrete, brick and stone structures and stabilise bases and soils, including in tunnels and metro. The mix is prepared at W/S 0.3, 0.4 or 0.5, with workability retention of 40, 60 or 80 min respectively; particles are no larger than 0.05 mm.
