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.
“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.

“GLOBALPOX-TAR”
Waterproofing and protective coating made of epoxy-bitmen for concrete and steel, as
internal and external coating for buried and submerged structures, e.g. sewage
systems, chemical industry, ect. Also suitable where application onto damp concrete
is inevitable.
“GLOBALCOAT-HR-90”
For waterproofing applications and anticorrosion applications on concrete and many
other substrate:
protective coatings, sewage and waste water treatment plants, bridge deck
waterproofing, truck bed lining, industrial and manufacturing facilities, ect.
“EPOX-EPW”
Superfine epoxy cement sealing mortar and temporary moisture barrier:
Waterproof yet permeable to water vapour, allows the substrate to breathe, good
adhesion after long-term water immersion, suitable for interior or exterior use, high
abrasion resistance, ectc.
Used on both vertical and orizontal surfaces of concrete, mortar or stone, the
thixotropic mortar can be applied as a thin layer coating, 0,5 – 2 mm thick.

"GELLING" THE RADIOACTIVE
WATER THROUGH A PARTICULAR
FORMULATION OF THE
"GLOBALFOM" LINE

A NUCLEAR MELTDOWN (CORE MELT ACCIDENT OR PARTIAL CORE MELT) IS A SEVERE NUCLEAR REACTOR
ACCIDENT THAT RESULTS IN CORE DAMAGE FROM OVERHEATING.
ONCE THE FUEL ELEMENTS OF A REACTOR BEGIN TO MELT, THE FUEL CLADDING HAS BEEN BREACHED, AND
THE NUCLEAR FUEL (SUCH AS URANIUM, PLUTONIUM, OR THORIUM) AND FISSION PRODUCTS (SUCH AS
CESIUM-137, KRYPTON-85, OR IODINE-131) WITHIN THE FUEL ELEMENTS CAN LEACH OUT INTO THE
COOLANT. SUBSEQUENT FAILURES CAN PERMIT THESE RADIOISOTOPES TO BREACH FURTHER LAYERS OF
CONTAINMENT.
SUPERHEATED STEAM AND HOT METAL INSIDE THE CORE CAN LEAD TO FUEL-COOLANT INTERACTIONS,
HYDROGEN EXPLOSIONS, OR WATER HAMMER, ANY OF WHICH COULD DESTROY PARTS OF THE
CONTAINMENT.
A MELTDOWN IS CONSIDERED VERY SERIOUS BECAUSE OF THE POTENTIAL FOR RADIOACTIVE MATERIALS TO
BREACH ALL CONTAINMENT AND ESCAPE (OR BE RELEASED) INTO THE ENVIRONMENT, RESULTING IN
RADIOACTIVE CONTAMINATION AND FALLOUT, AND POTENTIALLY LEADING TO RADIATION POISONING OF
PEOPLE AND ANIMALS NEARBY.

GROUND AND HISTORICALLY AS A MIDDEN) IS A SITE FOR THE DISPOSAL OF WASTE MATERIALS
BY BURIAL AND THE OLDEST FORM OF WASTE TREATMENT(ALTHOUGH THE BURIAL PART IS
MODERN; HISTORICALLY, REFUSE WAS JUST LEFT IN PILES OR THROWN INTO PITS).
HISTORICALLY, LANDFILLS HAVE BEEN THE MOST COMMON METHOD OF ORGANIZED WASTE
DISPOSAL AND REMAIN SO IN MANY PLACES AROUND THE WORLD.

PHYSICAL CAUSES OF CONCRETE DETERIORATION
ABRASION:
Dry attrition (wear on pavements and industrial floors by traffic).
EROSION:
Wear produced by abrasive action of fluids containing solid particles in
suspension (canal lining, spillways and pipes).
CAVITATION:
Loss of mass by formation of vapor bubbles and their subsequent collapse.
DETERIORATION BY FIRE:
Concrete is able to retain sufficient strength for a reasonably long time.
“EPOX-EPW”
Epoxy cement resurfacing mortar with high resistance against urban waste
water.
“EPOX-EPW” is a threepart, epoxy modified cementitious, thixotropic, fine
textured mortar for levelling and finishing of concrete, mortar or stone surfaces.

INJECTIONS / FILLING
2-component no-expanding polyurethane foam to stop water leakage and

“GLOBALFOAM-PU or NF”
Is a very low cost viscosity, elastic and solvent-free polyurethane injection resin.
In contact with water, a uniform, closed and therefore watertight pore structure
forms, which is elastic and flexible.
Is used for permanent watertight sealing with some flexibility to absorb limited
movement, in dry, damp or water-bearing cracks and joints in concrete, brickwork
and natural stone.
“GLOBALFOAM-WR”
Slow reacting injection resin with long pot life accelerated curing as soon as in
contact with water.
