OPR2 Applications
Aquacrete® OPR2 can be used in a range of scenarios, including:
- Rated ventilation seals and stoppings
- Strata stabilisation
- Roadway containment
- Support structures
OPR2 Performance
Aquacrete® OPR2 consistently exceeds industry overpressure performance standards, achieving up to 24 MPa in 28 days. It can be engineered to meet site-specific overpressures in excess of 100 psi. Its performance has been verified by full-scale blast testing in an underground mine, with results certified by independent engineering consultants.
