Mechanised digging of tunnels, wells, mines.
Tunnelling and rock digging sector requires formulations able to waterproof and consolidate rocks before and after the digging, fill cracks and natural rock cavities, seal cracks, consolidate crushed rock, concrete structures, stones or wood.
Products For Tunneling And Rock Digging
Polyurethane, silicone and epoxy resins are suitable to be used in this sector (applicable through injection). Resins for stabilising ground/rock before and after conventional digging or with TBM through injections.
Low viscosity epoxy systems that reticulate also at low temperatures and in the presence of damp. Suitable for consolidating structures in concrete, stone, wood etc...Application: applicable by low pressure injection.
Silicon-mineral-organic non-toxic and self-extinguishing formula with a high expansion capacity. Suitable for waterproofing and consolidating friable rocks and ground, filling cracks and cavities, ducting water in water table areas.
Two-component silicon-mineral-organic non-toxic and non-polluting formula, does not expand. Characterized by high mechanical strength and low viscosity. Ideal for consolidating land and rocks subject to landslide, waterproofing broken rocks, filling cracks and cavities, for waterproofing the walls of tanks and aqueducts.
KEMIEFOAM WR 140
Two-component polyurethane-polyurea protective elastomer free from solvents, plasticising, bituminous materials. Polyurethane resin extremely reactive on contact with water, suitable for sealing cracks, joints, empty spaces, as well as consolidating crushed rock or concrete areas, provided that there is humidity. After hardening the product has excellent chemical and mechanical resistance, abrasion resistance, waterproof but permeable to steam.
Non toxic and biodegradable sealant that can be used in tunnels dug with full-section mechanical cutter to prevent backfilling grout, water and mortar from penetrating the shield and reaching the digging face.
Non toxic and biodegradable sealant that can be used in tunnels dug with mechanical cutter, stable at considerable pressures and high lubricating power. Excellent resistance to mud, water and dust. Easily pumped, can be used on all rotary parts at the cutter head.
Poolkemie products are simple to use, technically innovative and provided with high mechanical characteristics.
