Blocksil® is a revolutionary British made liquid waterproofing membrane that provides a high performance protective surface suitable for flat & contoured roofs in industrial, mass transportation and civic applications from hospitals and factories to docks and railway applications.
Blocksil® is a single-part liquid polymer compound and optional non-woven needled polyester fleece reinforcement, which combine to form a seamless membrane which adheres to all irregular contours and surfaces, bridging cracks and holes up to 50mm diameter, while maintaining excellent flexibility.
It won't shrink, it's solvent-free and you could drink the rainwater from it were you so inclined!
Very Technically Advanced
Blocksil® is so technically advanced that accelerated ageing tests have shown that it could have a lifespan of more than 100 years.
The specially formulated polymer is brushed on, or applied by roller or power roller. It is straightforward and safe to apply - only basic hand and eye protection are necessary - and dries to a "rain-free" stage in 3-4 hours (fully dry in 16 hours).
High Durability
This really is the ultimate coating. Unlike many other membrane coatings, Blocksil® is not affected by temperatures in the range from -60C up to +200C and remains completely flexible and supple whatever the conditions.
Blocksil® is unaffected by UV, has excellent resistance to dilute acids and alkalis and is designed to be perfect for dense industrial areas where the air can be heavily contaminated. It is ten times more vapour permeable than most other high tech membranes and 100 times more than bitumen based products - yet fully water repellent.
