ROCKBOLT is an expanding, chloride-free dry mortar for rock bolts in tunnels. The product is available in bulk and large bags. The mortar expands up to 2% before setting. The expansion ensures good cavity filling and recasting around the bolt.
Rockbolt is based on environmental cement with reduced strength development at low temperatures (+5C). If you want faster firmness development at low temperature, you can add MAPECUBE 1 accelerator.
