LeakSeal® FibreSeal
Blue Waterproofing
A flexible, sprayable, fibre-reinforced hybrid polyurethane waterproofing coating for roofs, seams, penetrations, parapets and gutters — providing durable, seamless waterproofing and crack-bridging performance.
LEAKSEAL® FibreSeal BLUE Waterproofing is a high-viscosity, one-component, water-based hybrid polyurethane coating reinforced with glass fibres to deliver a flexible, seamless and highly durable waterproofing membrane. Designed for roof detail waterproofing and sealing, the system provides excellent adhesion, crack-bridging capability and long-term weather resistance without the need for a separate reinforcing membrane.
