Bituminous Sealant — Rubber-Modified Bitumen Joint Sealant (Pour Grade)

Bituminous Sealant is a single-component, ready-to-use joint sealant based on a rubber-modified bitumen formulation. It is poured or applied directly into horizontal joints and cracks, where it flows, self-levels, and cures to form a tough, flexible, and fully waterproof seal that bonds tightly to concrete, asphalt, brickwork, and most common construction substrates.

Supplied in pails, it is non-sagging on vertical applications and compatible with backer rod — making it a versatile, cost-effective solution for low-movement joint sealing across civil, infrastructure, and building projects.

• Single-component, ready to use — no mixing required; simply pour or apply straight from the pail
• Self-levelling in horizontal joints — flows into the joint cavity and forms a smooth, even seal without tooling
• Excellent adhesion to concrete, asphalt, brickwork, stone, and metal substrates without priming under normal conditions
• Cures to a tough, flexible, and permanently waterproof seal — resists water, moisture ingress, and chemical exposure
• Non-asbestos fibre reinforced — provides thixotropic, slump-free performance on vertical and inclined joint faces
• Stable across a wide temperature range — remains flexible in cold and does not soften excessively in heat
• Cost-effective and long-lasting — low maintenance once cured, with a service life measured in decades
