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.

TBM
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.

THEY CONSIST OF A ROD AND MECHANICAL OF GROUTED ANCHORAGE (RESIN INJECTION) COUPLED WITH SOME MEANS OF APPLYING AND RETAINING THE ROD TENSION. MECHANICAL FIXING ARE SUITABLE FOR HARD ROCK, WHEREAS GROUTED, FIXED LENGTH BOLTS CAN BE USED IN MOST ROCK TYPES. THE LENGTH VARIES BETWEEN 2 TO 8 M FOR RESIN INJECTION BARS, AND 3 TO 20 M FOR AN EXPANDING SHELL FIXING ON A BAR.
