Aussie Swell Red 940 Waterstop 16.4' per Roll

Aussie Swell Red is a high-performance hydrophilic strip waterstop made from a proprietary blend of sodium bentonite and butyl rubber. Engineered for use in concrete construction joints, this active waterstop expands upon contact with water, forming a durable, impenetrable seal that blocks water intrusion and resists hydrostatic pressure.

Unlike traditional PVC or rubber water bars, Aussie Swell Red does not require split forming, seam welding, or pre-formed intersections. Its self-swelling action allows it to inject into small voids and cracks, delivering superior waterproofing performance.

Key Features:

• Expands to form a watertight gel that seals joints and voids

• Conforms easily to irregular surfaces

• Resists up to 6 bar (60m) of hydrostatic pressure

• Withstands wet-dry and freeze-thaw cycles without performance loss

• Easy on-site installation with simple butt joints

• Effective on concrete, steel, and PVC pipe surfaces

Applications:
Ideal for use in construction joints, pipe penetrations, wall-to-floor joints, and irregular concrete surfaces. Suitable for both vertical and horizontal installations.
