Description:

ROCKBOND UNDERWATER MORTAR (RB UWM) powder is a blend of special cement powders, high quality graded sands and an unique combination of polymers and admixtures. The powder, when mixed with water, produces a mortar which is wash-out resistant and waterproof. The material develops a high early strength, and can be used above or below the waterline.

Features & Benefits:

• Portland cement based, polymer modified and microsilica enhanced.
• The mortars develop an excellent putty consistency for ease of application.
• Can be used above and below the waterline.
• Will not disperse, wash-out or break up underwater.
• Strong, impermeable bond to brick, stone, masonry, steel and concrete.
• Mortars can be built up to a level of existing profiles in one operation.
• The mortar can be finished to produce a smooth and attractive surface.
• The material will not contaminate canals, rivers, reservoirs or lakes.
• The powder contains no iron, high alumina cement, chlorides or deleterious substances.
• High yielding, economical, non flammable, non toxic, odour free, user friendly and safe to use in underwater environments.

Uses:

• Offshore locations and underwater applications.
• To repair and waterproof precast concrete, tunnels, culverts, sewers and pipes.
• To point and repair bricks, blocks and masonry above and below the waterline.
• The repair of concrete in tidal zones where time is limited.
• The protection of marine structures above and below the waterline.
• The consolidation of sea defences, harbours, jetties, docks and locks.
• Caulking material for gaps and joints, and for sealing shutters.
• In situations where a quick, early strength gain is required.
• To instantly stop and plug the flow of running water or grout through brick or concrete.
