Tape for the flexible waterproofing of expansion joints and cracks.

MAPEBAND FLEX ROLL is a Thermo Plastic Elastic (TPE) bandage that exhibits excellent flexibility and elasticity, offering distinct advantages to the user.

MAPEBAND FLEX ROLL can be easily joined using a hot air gun welding process as used in PVC and TPO membrane joining practices. This provides the installer the versatility of on-site joining and production of junctions and corners etc.

MAPEBAND FLEX ROLL is fixed to the concrete using Adesilex PG 4 which forms part of the potable water certified system. The bandage is firmly bedded into a layer of Adesilex PG 4 on either side of the joint or crack and the edges are then also encapsulated on the top side to provide a perfect bond and seal.

MAPEBAND FLEX ROLL provides excellent chemical resistance and is resistant to UV in exposed applications.
