Mataproof CEMflex Steel Plate Waterstop
CEMflex is a steel plate waterstop encapsulated in a patented, active coating which reacts with water and moisture when embedded in concrete to provide a watertight construction joint. It functions as both an active and passive barrier to the transmission of water through all non-movement construction joints (horizontal and vertical) in in-situ reinforced concrete. CEMflex may be used in both pressurized and non-pressurized water.
System Benefits:
- Active coating reacts with alkaline water and moisture to provide infinite sealing ability
- Excellent bond to concrete
- Only 3 cm of concrete cover on both sides are necessary to seal cold joints up to 8 bar (80 m water pressure)
- Bonding the overlaps is not required; overlap minimum of 5 cm held in place with provided clips
- Easy to install through reinforcing cage; or embed into freshly poured concrete, saving up to 80% of the time to install traditional PVC waterstop
- Rigid structure prevents collapse of waterstop from subsequent concrete pours
Applications:
- Construction joints in wall/floor areas in contact with pressurized and non-pressurized water
- Wall/wall and floor/floor construction joints or wall/celing areas
- Joints between prefabricated components: wall/floor, corner joints, and predetermined breaking points
