AquaMast cold bituminous waterproofing mastic — for foundations and piles

Mastics and liquid membranes

AquaMast bituminous mastic is supplied ready to use and is intended for coating waterproofing of structures buried in the ground: foundations and piles made of concrete, reinforced concrete, metal and timber. Absorbent substrates are pre-treated with AquaMast bitumen primer, and an alkali-resistant mesh is laid into the wet coat if necessary. The coating resists naturally occurring aggressive substances, water absorption over 24 h does not exceed 2%, and heat resistance is not lower than +80 °C. The mastic is applied at −10…+40 °C; it is not used on roofs or inside residential premises.
