Add to my wish list

Colmatec is a micro-perforated, flexible PVC injection sheath used for watertightness of shrinkage joints and construction joints which are cast in place. The micro-perforated sheath then allows the injection of a polyurethane resin (Pur Protect) to completely clog any cracks or gaps present beside the construction joint.

The Colmatec system can be delivered as individual parts, or as 100 m reels.

  • Very low consumption of injection product
  • 100 m reel
  • Easy to place
  • If nailing is impossible, spider clip are available
  • With the foam plug, the sheath remains dust tight until the injection
  • The colour plugs on the injection heads identify the circuits
LEVIAT technical advice


Colmatec, when combined with another watertightness system, such as Cemflex for example, allows any fitting or concreting errors to be compensated for. The building can also be left to work, compact and allow natural cracks to appear and, in case of infiltration, only the zone concerned will be injected.
