Key Features & Benefits

Exceptional Anti-Scour Resistance:

Maintains cohesion upon contact with water, resisting washout even under moderate currents (up to 3 knots).

Minimizes environmental turbidity and material loss.

Rapid Strength Development:

Achieves early strength for quick return-to-service.

High ultimate compressive strength ensures long-term load-bearing capacity.

Self-Leveling & Self-Consolidating:

Flows easily into complex geometries, voids, and narrow gaps without vibration.

Excellent penetration for sealing cracks and filling honeycombs.

Dimensional Stability & Low Shrinkage:

Minimizes cracking risk for durable repairs and foundations.

Excellent Bond Strength:

Adheres tenaciously to wet substrates (concrete, steel, rock).

Corrosion Protection:

Low permeability protects embedded steel reinforcement.

Easy Mixing & Placement:

Simple batching via conventional paddle mixers or grout pumps.

Suitable for tremie pipe, pump injection, or pre-placed aggregate methods.
