Revolutionary NEW development in waterstop technology
Improving choice, quality and service
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

Steel plate waterstop
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.
n Place directly into fresh concrete
n Fix with clips prior to pouring concrete
CEMflex VB makes an extremely good connection to the surrounding concrete. Minimum of 30mm of concrete cover needed either side of the joint
Water is stopped in the cold joint. Any water coming in contact with CEMflex VB will activate the crystallisation process
Prior to pourn Install by fixing to the reinforcement using the CEMflex
Omega Holder
n The overlapping of the lengths should be a minimum of 150mm and held at the joint by the Omega Holder
n Ensure at least 30mm of plate is covered by each pour
Post pourn Install by pushing the plate into freshly poured concrete to an
embedment depth of at least 30mm
n Lap the plates with a minimum of 150mm & fix with a CEMflex Clip
