VOLSEAL® 250 - Elastic waterproof coating
Verified by manufacturer 1 month ago
A cementitious flexible waterproofing coating.
Application
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.
- Basements.
VOLSEAL 250 is not designed for use as waterproofing membrane for plaza/ podium decks or green roofs.
Description
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.
Features and benefits:
- Excellent adhesion properties to concrete, masonry block and brickwork, and can be applied to green concrete.
- VOLSEAL 250 is a two component material with a mixing ratio of 2.5 parts powder (Part A) to 1 part liquid (Part B).
- Not designed for waterproofing structures subject to positive hydrostatic pressure.
- Not designed for use as waterproofing membrane for plaza/ podium decks or green roofs.
- Do not apply more than 4 mm total thickness.
- Do not apply VOLSEAL 250 to bitumen or asphalt.
