Kalmatron — penetrating waterproofing for concrete

Penetrating waterproofing

Kalmatron is the basic product of the penetrating range: a dry mix based on Portland cement with a complex of chemically active reagents, applied to concrete moistened to full saturation. The material is used for foundations and basements, tanks, swimming pools, hydraulic structures and dams. The watertightness grade of concrete rises by at least 4 steps and frost resistance by at least 100 cycles; the coating is resistant to sulphates and petroleum products and works from −60 to +130 °C.
