CEMflex VB is a waterstop consisting of a galvanised steel plate covered in a coating which reacts with alkalis to provide a watertight joint for use in all non-movement construction joints in concrete.

Approvals:

  • BBA Certificated
  • Drinking Water Approval Reg 31 (4) (b)
  • Animal Manure Resistance

CEMflex VB is an active waterstop that enables concrete to self-heal.

When fresh concrete is placed around the waterstop, the alkalinity of the concrete activates the coating producing a chemical reaction. This causes the coating to soften and penetrate any cracks in the concrete. It then crystallises and seals the concrete. Once installed the coating has infinite sealing ability, should alkaline water come into contact with the coating at any time, it will reactivate and repeat the sealing process.

Benefits:

  • A highly effective waterstop, suitable foruse in all non-movement joints in in-situ reinforced concrete
  • Watertight joints independently tested at 5 bar pressure
  • The coating crystallises and seals any cracks in the concrete
  • May be installed in all weather conditions
  • Will remain effective as a waterstop for the life of the structure
  • May be installed before the concrete is poured or placed into fresh concrete
  • Requires only 30mm of concrete cover either side of the joint to function correctly
  • Suitable for vertical and horizontal applications
  • Product is supplied ready to use
  • Offers strength and agility
  • Simple and quick to fit (no special tools or skills)
