Description
Rockbond 4.04 Underwater Concrete contains a blend of cement powders, high quality graded sands, an aggregate and a union of admixtures.
The micro concrete, 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.
This product has similar properties to Rockbond 4.03 Underwater Grout, but the material contains a rock aggregate and is applied to fill larger volume voids and horizontal/angled surfaces that require a layer that is 60mm or greater.
Supplied in 25kg tri-wall plastic lined paper bags.
Uses of 4.04 Underwater Concrete:
- General underwater void filling applications.
- Marine and fresh water concrete repair and protection.
- For use in hostile locations such as tidal and splash zones.
- For the repair of Seawalls, harbours, quays, 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.
Special Properties:
- Incorporates several anti-wash-out agents.
- Extremely high wash-out resistance.
- No “fog” or dispersion when placed or poured underwater.
- Extremely stable and will not segregate or bleed.
- Readily pumpable and stable under pressure.
- Self-levelling and self-compacting.
- Excellent underwater bond to brick, steel, and concrete surfaces.
- High ultimate compressive, tensile and mechanical strengths.
- Weather proof, very low permeability and resistant to chemical attack.
- Can be used above or below the waterline.
- Non-flammable, non toxic, user friendly and safe to use.
