CarboStop

For the coagulation, hardening and waterproofing in tunnelling, underground, Hydraulic, Maritime and Off-Shore Constructions

Description

CarboStop 102 is a water-reactive one-component polyurethane resin. CarboStop 102 is CFC and solvent free. The reaction begins when the mix comes in contact with water.

  • Stopping of water inflow under high pressure and speed ( salt water)
  • Coagulation and water sealing of loose rock.
  • Grouting of fine to grained sands.
  • Fixing of anchors, self drilling anchors and cable bolts in sand under water transit
  • Deep injection
  • Injection of cracks, honeycombs, cold joints and non-moving joints.
  • Injections of man-accessible sewer lines and tubes
  • Injection in simultaneous or sequential stages during the cement grouting,

(Carbo-Grouting System), and or for the automated compounded grouting, i.e., resin mixture + reactive, or non-reactive fillers for the filling of large voids under high water transit and pressure (Carbo-Block)

Instructions

CarboStop 102 ACC must be added for a controlled start of the reaction. Before the start of the pumping, the CarboStop 102 ACC is added in predestined quantity to the resin CarboStop 102. Herewith the reactivity of the grout can be adjusted to the given situation. Both components have to be mixed thoroughly. The prepared grout mixture can be stored for at least 48 hours without significant increase in viscosity under the condition that the grout mix is efficiently protected from moisture and water. However, a skin may form on surface of the liquid surface, due to reaction with the moisture in the air. This has gen- erally no further effect on the resin underneath, but we recommend to skim this skin and also prevent obstructions in the pump.

The mix of CarboStop 102/CarboStop 102 ACC is injected as a one-component grout that reacts strongly and hard- ens after the contact and interaction with a sufficient quantity of water. Should the area to be sealed contain an insuf- ficient quantity of water to trigger all the elements of the resin, then a complete reaction of the CarboStop 102 can be achieved by pre-, simultaneous-, or post injection with water.

When compared to two-component systems, the CarboStop 102 contained in the high-pressure hose does not hard- en out. However, please assure yourself that the valves are closed so that no water can enter the hose and trigger the reaction of the grout. Nevertheless we always advise to flush the pump with the cleaner CarboSolv D in order to prevent the pump and valves from sludging. Should the interruption exceed one day, we’ll always advise to lubricate the internal parts of the pumps and the hoses with CarboSolv S as well.

Shelf Life

CarboStop 102 and CarboStop 102 ACC are a moisture-reactive systems and very sensitive to contact with moisture and humidity, and are therefore filled under a protective blanket of dry nitrogen. The components can be stored for at least 12 months when kept dry and in closed original package. Once opened, the components should be used as soon as possible.
