Bridges cracks and seals membrane-lap T-joints
Repeated external loading does not impair waterproofing performance
Develops full-surface bonding to the substrate and membrane
High solids allow the design thickness to be formed in one application
Resistant to acids, alkalis, chemical attack and low temperatures
Typical application areas
Where this product fits
Composite waterproofing systems
Class I and II underground works and non-exposed roofs
Class I waterproofing of planted roofs or roof slabs
Complex details, difficult workmanship and high-risk leakage areas
Transport and Storage
Packaged in lidded steel pails; store different product types separately and prevent cross-contamination.
Keep away from fire, sunlight and rain; prevent impact and maintain ventilation below 40°C.
