Steel Plate Waterstop BPA-CEMflex® / CEMflex® technology
Steel Plate Waterstop BPA-CEMflex® VB is a steel plate waterstop coated with a patented special coating, which actively reacts with water when embedded in concrete to provide a watertight construction joint.
Steel Plate Waterstop BPA-CEMflex® VB functions as both an active and passive barrier to the transmission of water through non-movement joint (both horizontal and vertical), in reinforced concrete structures.
BPA-CEMflex® VB has been proven, through independent testing, to be effective at up to 8 bar (80m) water pressure. BPA-CEMflex® VB’s unique design makes it the safest, most cost-effective, and reliable waterstop available on the world-market.
Steel Plate Waterstop BPA-CEMflex® VB
BPA-CEMflex® VB elements are provided with a special coating on both sides. It is an active joint waterstop which provides the ultimate protection from water ingress throughout the lifetime of the concrete structure. BPA-CEMflex® VB comprises of a galvanised steel plate encapsulated in a special patented coating which reacts with alkaline water to provide a watertight joint.
The steel plate creates a physical barrier whilst the BPA-CEMflex® active coating reacts with the alkalinity of any water in the concrete to form Calcium Hydroxide (Free Lime) which supports the natural self-healing (sintering) process of the concrete to seal cracks and eliminate water ingress.
Unlike conventional crystallisation waterproofing the CEMflex® active process is a form of crystallisation that does not create and aggressive salts which could potentially have an adverse effect on the reinforcing steel which supports the concrete structure.

BPA-CEMflex® VB actively seals and heals all construction joints. An unique mineralisation and deep crystallisation process seals the joint and the concrete itself.

Permanent stop end formwork BPA-CEMflex® A
Permanent stop end formwork BPA-CEMflex® A is a result of an ongoing development process of the well tested and proven CEMflex® VB steel plate waterstop. The CEMflex® Technology has been successfully used in the market for many years. The CEMflex® A permanent stop end formwork is a simple adjustable formwork element with an effective waterproofing sealing behavior.
Sacrificial adjustable formwork BPA-CEMflex® A is a revolutionary new dual-purpose stop end formwork which doubles as a waterbar in non-movement joints. The BPA-CEMflex® A sacrificial formwork profiles are fully coated with the patented active crystalline BPA-CEMflex® coating. These easily adjustable waterproof shuttering elements are suitable for use as both horizontal and vertical sacrificial stopend formwork. Due to the active BPA-CEMflex® coating additional waterbar installation is not necessary.
The BPA-CEMflex® A sacrificial stop end formwork has been developed with the intention to offer a simple, flexibel and cost-effective stop end formwork solution which includes the joint waterproofing function.
