    Drainage membrane DELTA®-GEO DRAIN QUATTRO

    The unique four-layer protection and drainage system for installation depths of up to 10 m. With integrated self-adhesive edge.

    DELTA®-GEO DRAIN QUATTRO was already developed and used for permanent waterproofing in 1993 for the special use on pressure-sensitive surfaces, for example polymer-modified thick bituminous coatings (PMBC, formerly known as KMB) and guarantees a constant protection of the seal.

    Advantages

    • Unique compound of material
      DELTA®-GEO DRAIN QUATTRO consists of four different layers: perforated sliding film, drainage fleece, dimpled sheet and laminated geotextile. Thanks to the micro-perforated sliding film and drainage fleece, water standing between the membrane and the seal, which could exert considerable pressure on the seal, is reliably drained off.
    • Integrated self-adhesive edge
      The smooth overlap edge with integrated adhesive zone enables the strips to be easily connected to one another. This prevents backfill material from trickling in, so that the seal is additionally protected. This improves the stability of the individual strips as well.
    • 100 years of tested long-term resistance
      DELTA®-GEO DRAIN QUATTRO - with tested long-term resistance of up to 100 years - is free of recycling material in accordance with DIN EN 13252 and has passed tests for aging resistance by independent and accredited testing institutes. In this way, you can benefit from the permanent and sustainable protection of the whole building shell.
    • Ideal dimpled sheet
      The dimpled sheet has an optimal ratio of knob structure and weight per unit area. In this way and with a height of 9 mm it offers the perfect combination in terms of compressive strength, drainage performance and handling. The DELTA®-GEO DRAIN QUATTRO makes a drainage capacity of 2.4 l/s·m possible, even with an installation depth of 10 m.
    • Even load distribution
      Thanks to the sliding film, the contact area between the DELTA®-GEO DRAIN QUATTRO and the surface is 100%. So, the seal is optimally protected from punctiform loads from the filling material.
    • Protection against unavoidable subsidence
      Frequently occurring subsidence in the backfilled construction pit can lead to movements of the protective and drainage membrane but do not have a major effect on the waterproofing because the sliding film is loosely connected to the sealing membrane.
    • No silting up of the knob structure
      Thanks to its special structure and its characteristic opening width of 150 μm, the laminated geotextile is extremely filter-stable and prevents the dimpled sheet from silting up.
    • Conformity to standards and guidelines
      DELTA®-GEO DRAIN QUATTRO is CE-marked on base of DIN EN 13252 and meeting the requirements of DIN 4095 and DIN 18533 and the “Guideline for the planning and execution of polymer-modified bituminous thick coatings (PMBC)”.

    Application

    Due to its high compressive strength, the membrane can be used at installation depths of up to 10 m and thanks to its large drainage capacity it can handle even extremely high water loads.
    It can also be used as methane gas and radon drainage.

    The processing can be done either parallel or perpendicular to the top of the terrain. It must always be ensured that the printed geotextile faces the soil or backfill material.

    Overlaps of two membrane tracks on the long sides is done with the help of the self-adhesive edge. In case of transverse joints, the lower sheet must be laid at least 20 cm under the upper sheet.

    DELTA®-GEO-DRAIN QUATTRO can also be used for horizontal applications.
