Gidrobeton SRG-1 — cement-based waterproofing repair mortar

Thixotropic repair mortars

Gidrobeton SRG-1 is a dry repair mix based on Portland cement with aggregate up to 5 mm and chemically active reagents, applied with a trowel or mason’s trowel to moistened concrete, reinforced concrete, brick and rubble masonry. It is used to waterproof joints, junctions and screeds, including in tanks and treatment plants. At 28 days it reaches at least 50 MPa in compression and 1.5 MPa bond to concrete; watertightness is at least 12 atmospheres, frost resistance 200 cycles.
