Globalchimica produces chemical products for construction, mining, and tunneling. It has a research lab and quality control processes. Key products include: - Fire resistant foams for cavity filling, waterproofing cracks, and consolidating rocks. - Low viscosity resins for sealing cracks, bonding bolts, and consolidating unstable rock and soil. The resins cure quickly to load bolts. - Technical and commercial support is provided through a partnership for tunneling and mining projects.

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.

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.
