Cementitious flexible waterproofing coating. VOLSEAL 250 is a highly elastic waterproof coating consisting of aggregates, cement-based binders and acrylic polymers. Once cured, it forms an an impervious and elastomeric barrier with crack-bridging properties of up to 0.8 mm in width. VOLSEAL 250 has excellent adhesion properties to : concrete, masonry block and brickwork, and can be applied to green concrete.
Applications:
VOLSEAL 250 is suitable for waterproofing structures that are subjected to negative hydrostatic pressure and typically constructed of reinforced concrete, masonry block and brickwork. Typical waterproofing applications include lift pits, tanks, existing cellars and basements. VOLSEAL 250 is not designed for use as waterproofing membrane for plaza / podium decks or green roofs.
Packaging:
VOLSEAL 250 is packaged in 25 kg bags (Part A Powder) and 10 kg pails (Part B Liquid).
