Rockbond Underwater Mortars (RB UWMs)

Product Information Sheet:

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 an early strength, and can be used above or below the waterline. 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 2 years.

Special Properties

  • 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 an underwater environment.

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 stop and plug the flow of running water or grout through brick or concrete instantly.

Rockbond Underwater Super Accelerated Mortar (RB UWSAM)

Product Information Sheet:

The repair of concrete in tidal zones where time is limited. To stop and seal the flow of water or grout in brickwork or concrete. Caulking material for seals and joints, and for sealing shutters.

 

Description

ROCKBOND UNDERWATER SUPER ACCELERATED MORTAR (RB UWSAM) powder is a blend of special cement powders, high quality graded sands, water soluble polymers and an unique combination of accelerating agents. The powder, when mixed with water, produces a rapid early strength mortar for underwater void filling and concrete repairs at freezing temperatures, and to fast stop the flow of water through cementitious surfaces, masonry, brick and stone. The compound is ready to use, packaged in 25kg moisture proof durable bags and has a shelf life of 5 years.

Special Properties

  • Portland cement based, polymer modified and microsilica enhanced.
  • The mortar produces a rapid gain in high early strength at low ambient temperatures.
  • Strong, fast and permanent bond to stone, brick, masonry, steel and concrete.
  • Can be used above and below the waterline.
  • Will not disperse, wash-out or break up underwater.
  •  Impermeable, waterproof, weatherproof, damp proof, durable and permanent.
  • High yielding, economical, non flammable, non toxic, odour free, user friendly and safe to use in underwater environments.

Uses

  • For the fast filling and sealing of voids and quick repairs to concrete at freezing temperatures.
  • To instantly stop and plug the flow of running water or grout through brick or concrete.
  • The repair of sea walls in tidal and splash zones where time is limited.
  • Caulking material to instantly fill and seal voids, gaps and joints, and for sealing shutters.
  • In situations where a quick, early strength gain is required.
  •  For use above water, underwater, with running water and wet applications.
  • Designed for use during cold weather, low temperature applications and freezing conditions.

Rockbond Underwater Grout (RB UWG) and Concrete (RB UWC)

Product Information Sheet:

Description

ROCKBOND UNDERWATER GROUT (RB UWG) powder is a premixed cementitious grout powder specially formulated for underwater applications. The compound contains a blend of cement powders, high quality graded sands and a union of admixtures. The grout powder, when mixed with water, produces a material that is cohesive, mobile, self compacting and displays excellent resistance to washout when brought into contact with water. ROCKBOND UNDERWATER CONCRETE (RB UWC) has similar properties to the grout, but the material contains an aggregate and is applied to fill larger volume voids. The powders are packaged in 25kg moisture proof durable bags and have a shelf life of 2 years.

Special Properties

  • Incorporates a blend of several anti-wash-out agents
  • Will not “fog”, disperse or breakdown when placed or poured underwater.
  • Extremely stable, will not segregate or bleed under pressure, and is readily pumpable.
  • Self smoothing, self levelling and self compacting.
  • Excellent underwater bond to stone, brick, masonry, concrete and steel.
  • High ultimate compressive, tensile and mechanical strengths.
  • Weatherproof, waterproof, impermeable and resistant to chemical attack.
  • Can be used above and below the waterline.
  • High yielding, economical, non flammable, non toxic, odour free, user friendly and safe to use.

Uses

  • General underwater void filling applications.
  • Marine and fresh water underwater concrete repair and protection.
  • For use in hostile locations such as tidal and splash zones.
  • For the repair of seawalls, harbours, quays and jetties, ramps and slipways.
  • Fortification and repair of river and sea defences.
  • Repair and consolidation of water retaining structures, dams, pillars and bridge columns.
  • Waterlogged foundations, anchorages, pilings, conduits, pipes and sewers.
  • In situations where a quick, early strength gain is required.
