2-component resins
Soil Stabilisation
• Improving load bearing capacities of loose soils• Bonding and consolidating strata• Anchoring self-drilling anchors and cable heads• Umbrella injections
• Coagulation of loose soils• Umbrella injections• Tunnels: void filling, consolidation of fragmented rock,
pre-injections• Low polymerisation temperature• Organosol XP FR is M1 fire rated• 30-35 V expansion
• Rock consolidation• Grouting of injection anchors• Fixing of rock bolts• Injections into rough sands and gravel• Filling of large voids/cracks/crevasses• Fast reacting• High strength
