- Above or below grade · interior or exterior · vertical or horizontal
Why this one
- Flexes instead of cracking
Bridges hairline cracks up to 0.75 mm as the structure moves - Holds under pressure
No leakage at 1.5 bar hydrostatic pressure after seven days - Bonds to almost anything
Porous and non-porous substrates alike, 1.5 N/mm² tensile adhesion - Brush, roller, or trowel
No torches, no specialist applicator crew - Solvent-free and odourless
Safe in enclosed spaces such as water tanks and bathrooms - Costs less than torch-on
More economical than hot-applied membranes over the same area
