Newton 410 Geodrain is a two-core drainage sheet consisting of a non-woven geotextile filter layer thermally welded to a water impermeable HDPE (High Density Polyethylene) cavity drainage membrane. It can be used externally below ground in conjunction with a french drain, or land drain. Please note that Newton 410 Geodrain is not a waterproofing membrane. Primary waterproofing of the structure should be achieved first using LVM Damp Proofing Paint or Newton 402 or Newton 401.

Key benefits:

    • Prevents water pressure from bearing against the structure
    • Resistant to all chemicals normally found in the ground
    • Withstands stresses and movement acting as a slip membrane as the backfill settles
    • Allows for backfilling with excavated earth
    • Extremely strong material, minimising the risk of damage when backfilling even when no protection board is used
    • Very high compressive strength
    • Suspended soil particles (fines) are filtered out by the geotextile layer
    • Quick and easy to install with a range of ancillary fixing and installation products


Typical applications:

  • As the drainage layer of an externally applied waterproofing system, when used in conjunction with sheet applied, or liquid applied external tanking membrane to BS8102:2009
  • Protection of the structure from aggressive chemicals in the ground water
  • To prevent the build up of ground water to retaining wall


Installation tips:

  • Form a fillet where the basement wall meets the footing.
  • Walls should be damp-proofed with an LVM paint prior to installation 
  • Newton 410 Geodrain should be fixed in the top row of studs.
  • Place footing drain 200mm below basement floor level.
  • Use Newton capping strip at the top of the membrane at ground level.
  • Use perforated pipe for the land drain/french drain.
  • Use a well drained backfill.
  • Slope ground away from retaining wall where possible or drain well.
  • Always use 410 Geodrain in conjunction with a land drain/french drain.
