    Field of application

    • For use on floors/walls indoors and outdoors
    • Crack injection in concrete according to DIN EN 1504-5
    • Classification: U(D1) W(1/2/3) (4*) (5/30) *Temporary waterproofing only!
    • Moisture level: WF
    • Pre-injection in water-bearing cracks (WF)
    • Tested according to ZTV-ING (RISS), (BASt List)
    • Tested according to DIN V 18028
    • Filling voids in masonry/concrete after water ingress
    • Curtain injection


    • Temporary waterproofing effect
    • Expands rapidly and strongly
    • High chemical resistance
    • High flank adhesion
    • Preparation
      • Substrate requirements

        The flanks of the crack must be dimensionally stable and free from loose parts, sintered layers, oils, grease and other separating substances.

      • Preparations

        Plug the path of the crack if necessary.

        Use a suitable packer.

    • Preparation
      • Mixing ratio comp. A 1 : comp. B 1
      • Mixing time 3 min
      • Combination container

        Add the entire quantity of the hardener (component B) to the base compound (component A).

        Mix thoroughly with a slow-speed electric mixer
        (approx. 300 - 400 rpm).

        Mix for at least 3 minutes.

        Insufficient mixing is indicated by streaks forming.

        Pour the mixture into a separate container and mix again thoroughly.

    • Application
      • Application temperature: min. 5 °C
      • Working time 2 h
      • Application requirements

        Temperature of the material, air and substrate: min. 5 °C

      • Using suitable injection technology, inject the material from bottom to top.

        Remove packer, seal boreholes if necessary.

    • Application instructions
      • Conduct an analysis of the structural condition prior to injection.

        Adjust the injection pressure according to the properties of the building component.

        Additional injection with IR PUR 2K 150 using separate packer series

        Remove the skin that forms as a result of reaction with humidity and do not mix in.

        As a general principle, higher temperatures will reduce and lower temperatures will increase the times stated.

    • Working tools / cleaning
      • Injection device, hand-lever press, suitable mixing equipment, hammer drill

      • More detailed information can be found in the Remmers Tool Programme.

        Clean tools, equipment and splashed material immediately while fresh with V 101 Thinner.

        Take suitable protective and waste disposal measures when cleaning.

    • Storage / shelf life
      • Store frost-free and cool / protect for moisture / close containers
      • Shelf-life 24 months
      • If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 24 months.

    • Usage
      • - To be determined on a case-by-case basis
        - Dependent on the moisture level in the structure, crack width and component thickness
        - Approx. 0.1 kg/l void
        - Approx. 0.3-0.5 kg/running metre
        - Volume increase approx. 40x

    • General information
      • Unless otherwise specified, all of the values and application rates given above have been determined under laboratory conditions (20 °C). Slight deviations from these values may arise if the product is worked with on site.

        The actual amount of material needed depends on the size of the void. Proceed based on the results of the building condition analysis.
        Remember that surplus material may be needed depending on the application method.

        Do not allow condensation to form in the injection device.

        Once the work is finished, thoroughly empty and clean the injection device.

        The current technical regulations must be observed.

    • Disposal instructions
      • Larger quantities of leftover product should be disposed of in the original containers in accordance with the applicable regulations. Completely empty, clean containers should be recycled. Do not dispose of together with household waste. Do not allow to enter the sewage system. Do not empty into drains.

    • Safety / regulations
      • For professional users only!
