MasterLife 300D crystalline capillary waterproofing admixture used in shotcrete for damp areas

Location: Hard Rock Mines, South Australia

Project completed: Ongoing

Market sector: Waterproofing & Infrastructure

Products used:

  • MasterLife 300D
  • MasterLife SF 100

Shotcrete is widely used in Hard Rock mines for ground support, allowing the customer a safe and efficient mining operation.

In damp and wet areas, shotcrete may be difficult to apply where fall out can occur due to the shotcrete not bonding to the wet substrate. Additionally, when shotcrete is applied over damp or wet areas water usually penetrates through the shotcrete and then onto the roads. The water damage on the roads can get very costly for the
maintenance spent on the road as well as the damage caused to the equipment.

BASF proposed the addition of MasterLife 300D, a crystalline capillary waterproofing admixture, to the shotcrete mix in conjunction with MasterLife SF100, a dry powdered silica fume. MasterLife 300D admixture is an integral crystalline capillary waterproofing admixture for concrete. It is designed for use in above- and below-grade applications, and reduces concrete permeability effectively allowing the shotcrete to breathe.
