POLYMER RESINS FOR TUNNELLING
Introduction / Applications POLYMER RESINS FOR HARD ROCK MINING AND TUNNELING: - Pre-injection and Post-injection - Injection / Rock Bolting - Mine Backfill
INJECTION FOR TUNNELING: - Water stopping. Water ingress reduction and ground consolidation - Rehabilitation of tunnel linings - Consolidation and cavity filling
THE NAME PRODUCTS, DESCRIPTION AND CHARACTERISTICS: “GLOBALFOAM-SP (Fire resistant)” CAVITY FILLING - silicon-mineral-organic formula with a high expansion capacity studied for waterproofing and consolidating friable rocks and earth, filling cracks and cavities, ducting water in water table areas. Non-toxic and self extinguishing, no production of harmful fumes.FIRE RESISTANT.
“GLOBALFOAM-WR” and “GLOBALFOAM-WR-NF (Fire resistant)” WATER SEALING - 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 “GLOBALFOAM-PU” and “GLOBALFOAM-PU-NF (Fire resistant)” WATER SEALING - polyurethane resin, self-estinguishing,, suited for sealing of cracks, joints, cavity filling, and for consolidation of crusche manufacture made of stone or cement, in presence of dampness. In contact with water starts a chimica reaction that forms a closed-cells consolidating foam, which is waterproof and has a good chimica stability. FIRE RESISTANT “GLOBALSTONE” and “GLOBALSONE-LV50 (Fire resistant)” SEALING AND STRUCTURAL BONDING OF FISSURES AND CRACKS (FLEX) - STRATA CONSOLIDATION – Organic-mineral two components resin, not expansible, characterized by low viscosity, excellent chimica stability, mechanical resi stance and flexibility. Ideal for water-proofing fractured rock, consolidation of loose land and rock, crack and cavity filling. Especially suitable for bonding injection drill bolts because the resins cure within just a few minutes and the bolt can be loaded in a very short time. FIRE RESISTANT.

Schematic representation of erroneus procedures sometimes adopted when crossing fault zone. The sketch illustrates a real case in a gneiss rock mass. Tunnel collapse: 1. The TBM is pulled back to remove the gneiss block; 2. the TBM starts and a first collapse occurs; 3. fast ground injections “GLOBALFOAM-SP” are carried out; 4. the TBM restarts and a second collapse occurs with a large water inrush; 5. the TBM is permanentkly stopped.

When the most important problem is water the basic principle of pre-ground treatment is to utilized the ground surrounnding the tunnel as a load bearing ring and make it an integral part of the primary support and lining. This conceprt can be reached by creating a tight ground ring around the lining so that the hydrostatic pressure inthe outer permeable ground would act on the grouted ring instead of on the lining.
