Aquacrete Wet-Repel™ is a water-resistant, high strength product that is effective in water containment, strata consolidation, backfill containment and ventilation control. Along with other important properties, such as it’s high early strength and long term structural integrity, Aquacrete Wet-Repel™ typically absorbs less than 18% water whilst achieving a compressive strength of up to 25MPa. Aquacrete Wet-Repel™ is used in underground coal and metal mines for a range of applications that include:
  • Water-retaining bulkheads
  • Dam walls
  • Explosion-rated ventilation seals
  • Backfill barricades

Aquacrete OPR2 is a rapid-setting product that provides explosion-rated ventilation control, geology consolidation and sealing in underground mines. Developed almost 20 years ago, OPR2 pioneered the use of non-concrete materials in shotblast technology. In 1998, it became the first product in its category to undergo explosion-testing in a live underground mine. The results formed the basis of an engineering system that allowed mines to effectively predict the performance of a structural device exposed to a range of geotechnical and ventilation conditions. OPR2 is used in more than 80% of underground coal mines and a growing number of metal mines. It remains a product of choice for many of the world’s leading mining companies.

OPR2 is a versatile product that is trusted for a wide range of applications,including:

  • Rated ventilation seals and stop pings
  • Strata stabilisation
  • Roadway containment
  • Support structures

Mine Mesh

Aquacrete Mine Mesh is manufactured from 4mm wire and is hot dip galvanized. Made up of 160mm squares, mine mesh sheets provide the ideal backing surface for the application of Aquacrete shotblast solutions. Sized to suit a range of roadway dimensions, Mine Mesh is also suitable for a range of rib support and strata control applications.
