Verified by manufacturer 6 months ago

CETCO

A cementitious flexible waterproofing coating.

Jump to:
00 44 + (0) 7701315742 Website

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.
