X-Pruf KeyLok

Pre-applied mechanically bonded waterproofing membrane and liner

X-Pruf KeyLok is a continuously extruded sheet with a raised T profile that ‘locks’ into the concrete to produce a mechanical bond which is virtually impossible to destroy.  Since T profiles are cast into the concrete, it isolates the concrete from any harmful effects of corrosive chemicals.

 

Manufactured from plasticized polyvinylchloride (PVC-P), X-Pruf KeyLok can mainly be used as a waterproofing membrane for tunnels and concrete structures.  Standard thickness is 1.5mm and 2mm.

 

Advantages: -

  • T profile bonds integrally with concrete.

  • not affected by settlement.

  • provides a chemical resistant liner.

  • no primer required.

  • easy to weld overlaps.

  • not affected by ponded water.
