MASTERSTOP SK profiles are always installed inside the reinforcement. In doing so, sufficient concrete cover must be ensured.
The concrete cover should be at least 6 cm as otherwise the high swelling pressure of the bentonite may damage the concrete.
Pull off silicone paper and affix 2 rings of MASTERSTOP SK around the pipe to be waterproofed.
The rings must be at least 5 cm apart.
Butt joint ends, no overlaps.
The surface of the pipes must be rigid.
MASTERSTOP SK adheres to metal, plastic, PVC and stone.
Secure MASTERSTOP SK with binding wire if necessary.
MASTERSTOP bentonite swelling tape must only be processed when dry in dry weather conditions.
The geometry described must not be modified. Swelling tapes must not be installed if their rectangular geometry has been modified, or if they have become soiled or damaged!
Swelling tapes that have already expanded must not be installed!
Swelling tapes that have been installed and have expanded before placement of the concrete must be replaced!
