Gidrobeton SRG-1 — cement-based waterproofing repair mortar
Cementitious mix for repairing and waterproofing concrete, masonry, joints and screeds in tanks and treatment plants; compressive strength at least 50 MPa.

This is a cementitious rather than a polymer injection: the dry dispersed mix is mixed with water and pumped through packers into holes drilled in a staggered pattern. It is used for cut-off waterproofing of brick and rubble masonry and concrete, filling voids and static cracks, strengthening structures and injecting soils. The hardened mortar shows watertightness of at least W10, frost resistance of at least F1 200 and compressive strength after 28 days of at least 30 MPa.
