Wet-Repel™
Aquacrete Wet-Repel™ is a water-resistant, single component, high-strength product that provides ventilation control and geology consolidation in underground mines. Developed specifically for applications where conditions may result in erosion from water, Aquacrete Wet-Repel™ achieves a new benchmark in ventilation control performance.
Product Features
Safer
- Low toxicity
- Fire resistant
- Anti-static
- Creates an explosion-rated ventilation control device
- Cures to off-white colour
Faster
- Aquacrete Wet-Repel™ can be applied to any desired thickness in a single application
- Aquacrete Wet-Repel™ is rapid-setting and achieves the specified rating within 24 hours and a compressive strength of 17 MPa in as little as 48 hours and up to 25 MPa in 28 days
- Aquacrete Wet-Repel™ does not slump
Stronger
- Aquacrete Wet-Repel™ complies with mining industry over-pressure and thickness requirements for ventilation control devices (Queensland Department of Mines & Energy)
- Product certification has been issued by an accredited National Association of Testing Authorities (NATA) laboratory for over-pressure performance in a live underground blast test
Product Applications
In addition to addressing more severe gas and water ingress concerns, Aquacrete Wet-Repel™ is increasingly specified by underground mines throughout Australia for a wide range of applications.
These include:
- Rated ventilation stoppings
- Rated ventilation seals
- Non-rated segregation stoppings
- Dam walls
- Bulkheads
- Overcasts and overcast wings
- Rib consolidation and longwall rib consolidation
- Stopping and seal repairs
Product Testing & Certification
To ensure that Aquacrete Wet-Repel™ conforms to the most stringent industry standards, testing and certification is undertaken by laboratories approved by the National Association of Testing Authority (NATA). These include Western Geotechnics Group.
