Parchem Hydrotite Dss0220 Ad 25m Roll

Hydrotite DSS0220 AD is a co-extruded hydrophilic waterstop designed for concrete construction joints where watertight integrity is critical. It features a unique dual-action profile, combining a non-swelling EPDM rubber core with a hydrophilic outer layer that expands upon contact with water, creating a durable and reliable barrier against water ingress.

The AD version includes a factory-applied self-adhesive backing for quick and secure installation, reducing the need for separate adhesives on site.

Key Features:

• Dual swelling action – ensures rapid and controlled expansion when exposed to water

• Self-adhesive backing (AD) – simplifies installation and enhances bond to substrate

• Controlled expansion – prevents damage to fresh concrete while ensuring tight sealing

• Flexible and easy to apply – conforms to irregular surfaces and tight spaces

• Durable and chemically resistant – suitable for long-term use in harsh environments

• Re-swells repeatedly – maintains performance over multiple wet-dry cycles

• Non-toxic and environmentally safe

Typical Uses:

• Construction joints in water tanks, basements, tunnels, retaining walls, and culverts

• Pipe penetrations, kicker joints, and concrete-to-concrete interfaces

• Suitable for both vertical and horizontal joint applications

• Ideal for water-retaining and water-excluding structures

Dimensions:

• Profile size: 22mm x 5mm

• Supplied in 25m rolls

Installation Notes:
Ensure clean, dry concrete surfaces. Peel off the protective film and press firmly into place. Additional mechanical fixing may be used in vertical or overhead applications. Protect from moisture until concrete placement.
