Rawmat® Pre-hydrated Bentonite:
Product Description
BBA Certificate No. 97/3337 (148KB)
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.
How does bentonite work?
The natural sodium bentonite clay will absorb water and expand up to 16 times its dry volume when in contact with water. When confined, e.g. between the ground and the floor slab, this tendency to swell generates substantial swell pressures preventing the passage of water. When correctly installed, the Rawmat / Rawseal acts as an effective hydrostatic seal.
An important factor affecting the amount of swell achieved is the quality of water hydrating the bentonite. The significant advantage of the pre-hydrated system is that the initial hydration occurs under factory controlled conditions.
Unlike the dry systems, which are prone to shrinkage and cracking, the Rawmat pre-hydrated bentonite is highly resistant to the effects of water contaminants.
These contaminants induce cationic exchange in dry bentonite systems causing them to have a reduced swell, shrink and crack as the clay converts from sodium bentonite to the calcium form.
Why you should use Rawmat / Rawseal
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.
Additionally the Rawmat / Rawseal products:
- Can be installed on damp and uncured substrates, and in inclement weather
- Require no priming
- Can be nailed to the substrate
- Lose no bentonite when handling, folding or cutting
- Are highly resistant to chemicals and hydrocarbons
- Are natural products with an indefinite life
- Can be installed onto a variety of substrates including; concrete, rock-face, compacted sub-base, shutters etc. Also onto uncured or wet substrates, in any weather
- Self heal when cut or damaged
- Britisih Board of Agrément (BBA) Approved (Cert. No. 97/3337, 2nd Issue)
Installation Advantage
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.
