TamPur RBG


TamPur RBG A (Rock Bolt Grout) is an injectable, two-component solvent-free, polyurea-silicate grout. TamPur RBG A has been formulated for securing and sealing rock bolts in mining and tunnelling applications. It is designed to instantly thicken after injection retaining a thixotropic nature within the rock bolt hole to avoid reflux and allow sufficient time for installing solid rock bolts. It is especially effective in vertical bolting applications and can also be injected through SDA’s (Self-Drilling Anchors). Low in peak exotherm reaction and heat development compared to polyurethane.

There are three versions of TamPur RBG available, Slow, Standard and Fast set, in order to meet the requirement for different application conditions and processes.
