TamPur RBG (Rock Bolt Grout) is an injectable, two-component, silicate modified, solvent-free, polyurethane grout. RBG 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).
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.
