    Product Name

    CarboStop R 102 is a fast water-reactive, one-component resin that contains no solvents. To accelerate the reaction, CarboStop 102 ACC is added. The reaction begins upon contact with water. Once cured, the material forms a rigid-elastic polyurethane foam with a high percentage of closed cells in its compacted state.

    Applications

    ► Stopping water ingress (including saltwater) under high pressure and high flow conditions
    ► Stabilization and waterproofing of fractured or deteriorated rock formations
    ► Injection into fine to medium-grained sands and soils
    ► Anchoring and fixation of anchors, self-drilling anchors, and cable anchors in water-bearing sand
    ► Injection during cement grouting, either simultaneously or alternately (Carbo-Grouting method)
    ► Automatic combined injection, i.e., a mixture of resin with reactive or non-reactive fillers, for filling large voids under conditions of high water inflow and pressure (Carbo-Grouting)

    Component Description

    CarboStop R 102 is a resin composed of modified isocyanates and additives.

    CarboStop R 102 ACC is a catalyst blend used to adjust and control the reaction rate.

    Key Advantages

    ► Upon contact with water, the resin components react to form a rigid-elastic foam, effectively stopping water ingress.

    ► Excellent adhesion to all types of surfaces.

    ► The prepared reaction mixture can be stored for at least 48 hours without a noticeable increase in viscosity, provided that exposure to humid air is prevented.

    Operating Principle

    Before use, a sufficient amount of CarboStop 102 ACC is added to CarboStop 102 resin to adjust the reactivity of the injection mixture according to site conditions. The recommended application temperature range is from +5°C to +30°C.

    CarboStop 102 / CarboStop 102 ACC is injected into water-bearing areas through a packer (injector) as a single-component material using a manual, electric, or pneumatic pump. Upon contact with water, the reaction mixture expands significantly and cures into a solid foam.

    Packaging

    CarboStop R 102 – 20 kg canister.
    CarboStop R 102 ACC – 1 kg plastic bottle.

    Storage

    Store in a dry place in the original tightly sealed packaging at temperatures between +5°C and +30°C. Shelf life is 12 months from the date of manufacture.

    Recommendations

    Before use, the resin must be conditioned for at least 24 hours at a temperature of no less than +20°C.
    Localized overheating of the canister walls must be avoided.
    If the area to be sealed contains insufficient water, complete curing of the resin can be achieved through pre-injection or post-injection of water.

    Equipment

    Compact single-component injection pumps with manual, pneumatic, or electric drive, along with injection accessories such as packers and sealing packers.
