  2. 2. 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-M” 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.

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.
