Dimpled High Density Polyethylene Protection & Drainage Membrane with a Polyester Geotextile Layer.

abe.®drain G is a dimpled high density polyethylene protection and drainage membrane combined with a polyester geotextile layer which offers great resistance to all chemical agents usually found in soil and groundwater and to mechanical compression.

abe.®drain G is used to effectively drain water in roof gardens and planters in conjunction with a geotextile and protective membrane such as Index Defend H.

Other uses are: 

  • Tanking.
  • Retaining walls.
  • General purpose.
  • Good value.
  • Resistant to chemicals usually found in soil and groundwater.
  • Anti-root.
  • Protection of waterproofing membrane.
  • Excellent drainage capacity.
  • Thermal insulation.
  • Extra strength.
  • Secondary waterproofing system.
Cautionary Note

Horizontal Application

The surface area must be waterproofed according to a.b.e.® Construction Chemicals’ specifications. This is not a primary waterproofing membrane but is recommended for buried dual layer system applications. The first layer consisting of a 3mm torch-on will be abe® unigum followed by an antiriot bituminous membrane such as Index Defend H. Lay the abe.®drain G with the dimples upwards. Should it be necessary to overlap then 75mm would be sufficient (3 dimples). Apply super laykold waterproofing tape 100mm wide along the flat part of the product for this purpose. Spread out the soil according to the instructions of a qualified landscaper.

Vertical Application

For the Drainage and Protection of Walls:

The surface area must be waterproofed with Index Fidia P/ Indextene according to a.b.e.® Construction Chemicals’ specification. Ensure that the waterproofing membrane is completely covered with abe.®drain G for maximum protection. Measure the height of the wall including a flap which must be folded back and wrapped around the drainage pipe. Allow an additional 100mm above the finished ground level before cutting the sheet. Should it be necessary to overlap then 75mm would be sufficient (3 dimples). Apply super laykold waterproofing tape 100mm wide along the flat part of the product for this purpose. Install the sheet with the dimples and the geotextile towards the soil. To join the drainage pipe to the inside of the geotextile, detach the geotextile from the abe.®drain G up to 1 metro in height. Place the drainage pipe on the abe.®drain G after having first placed a layer of drainage material under the pipe. Wrap the detached geotextile under the pipe. Cover the pipe with some drainage material to keep everything in place before backfilling. Finish off the abe.®drain G at least 100 mm above the finished ground level and cover with a counter flashing


Install abe.®drain G as supplied using an overlap of 75mm between the sheets resulting in an overall coverage of 45m2 per roll.
