The Rawmat Pre-hydrated Bentonite tanking system is designed for protection of concrete foundations and vertical walls from aggressive soil attack, dampness and vapour transmission.
The advantages of Rawmat is that it can be installed directly onto compacted sub-bases, concrete substrates or applied to sacrificial shutters and steel piles. It also self-heals when damaged and can be installed on wet substrates.
The Rawmat tanking system is the premier tanking system and used in challenging tanking applications.
Unlike dry bentonite systems the Rawmat membrane and Rawseal water stops are resistant to chemical degradation (cationic exchange), are easy to install and also have the ability to withstand minor movement in the structure.
Joining two sheets of Rawmat could not be more simple.
The nature of Rawmat enables a self sealing joint to form at all laps without the need for the addition of bentonite between the joints.
The membrane can be simply trimmed and cut with a utility knife to fit around pipes, inlets, posts and other protrusions. Rawmat has a unique solid form which can be cut without any loss of bentonite, ensuring a secure seal in all cases.
Furthermore, Rawmat can be installed on damp substrates.
