Applications
- Filling gaps between reinforced concrete and precast elements
- Grouting of U-channels for glass balustrades
- Small-scale repairs of concrete honeycombing and bolt holes
- Structural concrete grouting repair
- Grouting of bridge bearings and machine baseplates
- Water-retaining/waterproof structures such as water tanks and swimming pools (non-toxic and safe)
- Underwater or tidal zone works
Advantages
- Non-shrink with micro-expansion — controlled early expansion, no drying shrinkage at 28 days, ensuring dense filling
- High strength — 28-day compressive strength of 70 N/mm² with excellent load-bearing capacity
- Multiple consistencies — adjustable by water dosage to plastic, flowable or fluid state
- Eco-friendly and safe — chloride, nitrate and sulphate free; no hydrogen gas expansion; non-toxic, suitable for drinking water structures
- High durability — low permeability, impermeability time > 250 s (Figg air permeability test); no bleeding, no segregation, stable placement for uniform filling
