    Field of application

    • For use indoors and outdoors
    • Strengthening hollow and loose masonry (according to WTA Code of Practice 4-3)
    • Filling joints and boreholes
    • Preliminary injection of boreholes in multi-stage injection


    • Low viscosity (very good flow properties)
    • Low shrinkage
    • High sulphate resistance and low active alkali content (SR/NA)
    • Preparation
      • Substrate requirements

        Drilling channel must be free of drill dust.

      • Preparations

        Subsequent horizontal waterproofing of masonry

        Production of drill holes:
        Single row, diameter 18 - 30 mm, distance 10 - 12.5 cm, angle of inclination approx. 45°, drill hole depth up to approx. 5 cm before end of wall.

        For walls > 0.6 m thick, it is recommended to make the series of drill holes on both sides.


        Strengthening hollow masonry

        Creation of drill holes: diameter 18 - 30 mm, angle of inclination approx. 45°, hole depth up to max. 5 cm from end of wall.

    • Application
      • Application temperature: min. 5 °C max. 30 °C
      • Bore hole saturation / Pressure injection
      • Application requirements

        Temperature of material, environment and substrate: min. +5 °C up to max. +30 °C

      • Filling voids

        Pressureless, via funnel.

        Low pressure filling via suitable injection equipment and injection packers.


        Subsequent horizontal barrier - multi-level injection -

        Pre-inject/fill hollow masonry via drill holes.

        Pierce filled holes with a lance/pin after stiffening.


    • Application instructions
      • Once it has hardened, mortar must not be made workable again by adding either water or more wet mortar.

        Protect wet mortar surfaces against frost, rain and drying out too quickly for at least 4 days.

        Please contact Remmers Technical Service (phone +49 5432 83900) before applying with machine processing.

    • Working tools / cleaning
      • Bore hole saturation / Pressure injection
      • Mixing tools, hopper, injection packers, suitable injection pumps (e.g. Desoi)

      • Clean tools with water while the material is still fresh.

    • Storage / shelf life
      • Protect form moisture
      • Shelf-life 12 months
      • If stored in an unopened container and in a dry place, the product will keep for approx. 12 months.

    • Usage
      • 1.2 kg / l void
      • Approx. 1.2 kg/l void

      • Apply to a large enough trial area to determine the precise amount required.

    • General information
      • May contain traces of pyrite (iron sulphide).

        Do not use on gypsum-based substrates.

        The mixing water must be of drinking water quality.

        Low chromate content in accordance with Directive 2003/53/EC.

        Always set up a trial area/trial areas first.

        The characteristic data of the product were calculated under laboratory conditions at 20°C and 65% relative humidity.

        Current regulations and legal requirements must be taken into account and deviations from these must be agreed separately.

        The relevant test certificates must be observed when planning and carrying out work.
