Description

Keep water out and protect your structure with our high-performance Swellable Water Bar, a hydrophilic rubber seal engineered for concrete construction joints. This advanced water stop expands upon contact with water, forming a permanent watertight barrier that prevents leakage through joints, cracks, and penetrations in concrete.

Manufactured from high-quality hydrophilic rubber and bentonite composites, the water bar reacts quickly with moisture to increase its volume several times, tightly sealing gaps that ordinary PVC water stops can’t handle. It’s ideal for construction joints, precast elements, basements, retaining walls, tunnels, lift pits, water tanks, and foundations where reliable waterproofing is critical.

The Swellable Water Bar offers an easy and flexible installation process. Fix it to the surface using adhesive or nails before the second pour of concrete — no welding, heating, or complex equipment required. Once installed, it automatically self-seals when water pressure occurs, ensuring long-term protection even under fluctuating moisture conditions.

Unlike traditional water stops, this hydrophilic swell seal delivers active waterproofing performance, adapting to micro-movements and structural cracks over time. It’s durable, chemical-resistant, and tested for long-term elasticity, making it perfect for Kenya’s diverse construction environments.
