A formulated blend of sodium bentonite and butyl rubber, designed to be used as an active waterstop which reacts with water to seal construction joints within concrete. The seal resists hydrostatic pressure, in excess of 6 bar (60 m), by swelling up tp 270% if needed, stopping the passage of water through the joint.

Due to the sodium bentonite content, on contact with water, TT Waterstop will swell within its confinement, self injecting into localized honeycombing and minor fissures.

Features and benefits:

Non-dimensional swell allows complete injection to surrounding voids.
Conformable – can be applied to a range of irregular substrates.
Resists in excess of 6 bar hydrostatic pressure.
Simple butt-jointing on site application.
Reproducible swell after wet-dry cycle.
Unaffected by freeze/ thaw cycle.
The product is resistant to normal construction site activities, is unaffected by extremes of temperature and humidity and does not require any form of protection.
The swelling capacity provides the capability of the product to seal minor cracks and voids.
The product does not prejudice the fire-resistant properties of the building and will not contribute to the development stages of a fire or present a smoke or toxic hazard.
The gelling of sodium bentonite is adversely affected by the presence of electrolytes (particularly trivalent ions) and may also be affected by the presence of soluble cations as those found in chalk or lime soils. In such cases please seek advice from Triton’s technical team. The product is not affected by organic contaminants.

Limitations:

TT Waterstop is not designed to function in movement/ expansion joints.
TT Waterstop is designed for minimum 20 N/mm² reinforced concrete and requires confinement and a minimum 75 mm cover to all sides.
TT Waterstop should not be subjected to submersion or remain in contact with water prior to concrete pour.
If the product exhibits any considerable swell prior to concrete pour it must be replaced.
If sea water is present or ground water contamination exists or is expected, please consult the Triton technical team.
