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

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.
