Description:

ROCKBOND UNDERWATER ACCELERATED MORTAR (RB UWAM) is used at low temperatures, or when a rapid gain in early strength is required at 20oC. The mortar powders are ready to use, packaged in 25kg moisture proof durable bags, and have a shelf life of 5 years.

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.

• 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.
