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. Master Builders Solutions 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.
