Cold-applied, single-component polyurethane waterproofing membrane with exceptional flexibility, adhesion, and durability.
HIGHSEAL PU is a single-component, solvent-based polyurethane waterproofing membrane designed for superior flexibility, durability, and crack-bridging capabilities. It offers excellent adhesion on multiple surfaces and is perfect for both new construction and refurbishment waterproofing projects, including metal, concrete, and wet areas.
HIGHSEAL PU are pre-mixed and ready to use.
Easy application by squeegee, brush, roller or airless spray.
Resistance to UV lights and weather conditions.
Crack-bridging up to 2mm.
Bonds effectively to various substrates like concrete, brickwork, asphalt, and metal, ensuring reliable and long-term protection.
HIGHSEAL PU are known for their long-term performance and resistance to weathering, aging, and chemical attack.
HIGHSEAL PU provide strong adhesion to metal, excellent durability against harsh weather, and its ability to withstand expansion and contraction of the metal without cracking.
HIGHSEAL PU are widely used for waterproofing bridge decks, providing a protective coating against water ingress, corrosion, and wear.
It can be applied to concrete, metal, asbestos roofs, old bitumen felts, PVC membranes, and more.
In many cases, priming enhances adhesion, especially on porous or chalky surfaces. Check substrate condition before skipping this step.
Final curing is achieved in 7 days. However, it becomes touch-dry in a few hours depending on ambient conditions.
