Hydrophilic Expanding Waterstop Tape
Pronil ACR is a new generation, high performance acrylic polymer based expanding tape. In a totally dry state it shrinks to its original installation dimension, then re-expands on contact with water — used in concrete construction to seal construction joints including wall-to-base connections, pipe entry systems, and interface sections between existing and new concrete.
- Concrete construction joints
- Wall-to-base connections
- Pipe entry systems
- Interface sections between existing & new concrete
Application & Performance
How It's Applied
Conformable across a variety of irregular substrates, ACR 300 forms an impermeable barrier against water once embedded in concrete. It requires no welding and no hardening time — installed with a simple overlap joint on site, stored in its original moisture-proof wrap in cool, dry conditions away from sunlight until use.
- InstallationOverlap joint, no welding
- Available Sizes5×20mm, 10×20mm, 20×25mm rolls
- ColourRed
