PRODUCTS FOR TUNNELLING, MINING AND UNDERGROUND EXCAVATION
GLOBALFOAM and GLOBALSTONE, mono-component or two-component foams and resins, expanding and not expanding, rigid and flexible, elastic and plastic.
For their application we suggest the use of expansion injectors equipped with packers.
Main fields of application of GLOBALFOAM and GLOBALSTONE:
- dams and hydraulic works
- fissures and cavities
- friable and loose soils/rocks
- Stabilization of rocks using anchor rods (fiberglass or steel)
- Waterproof of fractured rocks
- water conveyance in water bearing stratum
- Rock Bolts and anchors
- coating and waterproofing of walls of reservoirs and aqueducts
- sealing cracks of the concrete and /or gas and liquids.
GLOBALFOAM HF hydrophilic foam for injection, it reacts with water without any hardener.
GLOBALFOAM HG thanks to its lubrication properties, it helps reducing grip between soil and digging equipment. It can be used with GLOBALCRIL 46.
- soil conditioning during mechanical dig with EPB machines.
GLOBALSPERSE – high performance liquid dispersing agent.
- Dispersion/breaking up of highly cohesive clayey land with consequent decrease in viscosity, during TBM excavation work.
- Dispersion, breaking up and stabilisation of fine compact and cohesive land in general (bentonite, kaolin, etc.).
- Facilitate the resumption of excavations with milling cutters after long pauses.
GLOBALSEAL sealants for underground excavation with TBM (tunnel boring machine) .
