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:
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.
