QUICSEAL 702 is a hydrophilic butyl rubber swellable waterstop which has the combined properties of a rubber-based sealant and butyl sealant. It swells in a controlled manner when exposed to moisture and forms a self-healing joint material around the substrate. However, the material does not expand prematurely and does not absorb water from the fresh concrete poured against it, and helps to minimise any pre-expansion when the joint comes in contact with water.
Unlike many other clay-based products, QUICSEAL 702 will not expand to a point that the hydration process leads to the possible disintegration of the waterstop. It is ideal for use in both horizontal and vertical construction joints.
Uses
- Preventing the passage of water through non-movement joints in new cast in-situ concrete and between new and existing concrete.
- Example: joints in potable water tanks, secant piled walls and diaphragm walled basements, pilecaps, etc.
- Civil Engineering works; tunnels, box culverts, sanitary and stormwater manholes, etc.
- Above and below grade precast panels
- Integral sealing for joints in cast in-situ concrete where conventional waterstops are impractical to use due to limited access.
- Wrapping around pipe penetrations.
