Waterproof Retaining Wall Liquid Membrane :  

ARDEX WPM 320 (Sheltercoat Retaining Wall - 1 Part) Bitumen emulsion waterproofing membrane. Contains root inhibitors that repel most root growth without killing the plant. Excellent adhesion - can be applied to damp or dry substrates. Compatible with Ardex bitumen torch applied membranes.   


Ardex WPM 320 (Sheltercoat Retaining Wall) is a one component liquid applied, latex modified, bituminous elastomeric waterproofing membrane. When cured it forms a permanently flexible waterproof lining to most building surfaces. It is tough, economical and easy to use. Specially formulated Ardex WPM 320 contains a premium root inhibitor that repels root growth without killing the root. Designed primarily for areas covered or exposed to soil, it has excellent adhesion properties, can be applied to damp substrates. Ardex WPM 320 is waterbased, has almost no odour and is safe to use. Where used externally, Ardex WPM 320 should be protected from Ultra Violet light.   


  • Water based: safe, low odour.
  • Easily applied: single pack, high build, long pot life.
  • Tough/durable: provides long term protection.
  • Contains an effective root inhibitor that repels most root growth that may damage the membrane without killing the plant.
  • Excellent adhesion: can be applied to damp or dry substrates.
  • Compatible with Ardex bitumen torch applied membranes.  


Concrete, screeds/renders - cured for a min 28 days and 14 days respectively. Alternatively apply a barrier coat of Ardex WPM 300 (HydrEpoxy 300) as a barrier coating to fresh or wet substrates).

Masonry and concrete blocks - voids filled, sharp edges and protrusions should be removed to give flush finish.


  • Below ground tanking (not hydrostatic situations).
  • Planter boxes.
  • Retaining walls.
  • Lapping Ardex acrylic facade membrane to Ardex bitumen torch applied membranes.  

The product should not be used under tiles. Membranes containing bitumen can cause discolouration and debonding of tiled surfaces over time.   


Ardex WPM 320 will not resist root growth from large trees or other plants placed in close proximity. ARDEX WPM 320 coated surfaces must not be backfilled until the coating is totally dry and cured, as the coating will fail to cure altogether. Do not apply Ardex WPM 320 if the surface temperature is below 10oC or above 35oC. Do not apply if rain is imminent. Do not leave membrane exposed to direct UV rays for more than 3 weeks. Do not use solvent-based adhesive or sealers on top of membrane.   


Surface preparation

The surface to be coated should be clean, sound and free from oils, greases and flaking paint. New concrete should be cured for 28 days (or a barrier coat of Ardex WPM 300 (HydrEpoxy 300) applied) prior to application of membrane and the surface pores must be open. All cracks or holes exceeding 2mm are to be repaired before application commences. Surface may be slightly damp but must be free from seeping moisture. Surface to which the coating is to be applied should be smooth with no sharp edges to ensure a uniform film thickness is acheived.   


Ardex WPM 320 is self-priming on most surfaces. Wet or freshly placed concrete surfaces should be sealed with Ardex WPM 300 (HydrEpoxy 300) in one coat at a coverage rate of 3.0 square metres per litre. Porous substrates such as aerated concrete should be primed with Ardex WPM 320 mixed with 50% water.   


Apply a bead of elastomeric sealant to all expansion joints, corners, wall to floor/footing junctions and where movement will occur.   

Apply 2 coats of Ardex WPM 320 at a total rate of 2.0 litres per m2, and ensure full coverage with brush or roller. A reinforcing fabric should be used between coats in all vertical and horizontal corners or other possible movement joints. Ardex WPM 320 may be fully reinforced if required such as over concrete block walls. When dry, check for pinholes and rectify if necessary.   


Once the membrane has cured, and prior to backfilling a suitable protection material must be applied over the membrane. Ardex Protection Boards or Geotextile Fabric covered drainage cell are recommended. The protection boards should be installed using duct tape or other suitable means without puncturing the membrane.   

COVERAGE 1 x 20 litre unit will cover approximately 10m2 after two coats (recommended total dry film thickness minimum 1.0mm).   


Allow 1-2 hours between coats, unless a reinforcement material is used between coats. In this case, the second coat can be applied immediately after the mat has been installed in the wet first coat. The membrane is fully dry in 24 hours, after which it should be protected with ARDEX Protection Boards or Geotextile Fabric coated drainage cell. Backfilling should not be carried out until full cure is achieved after 7 days.   


Ardex WPM 320 is non-hazardous and non-dangerous. Do not breathe gas/fumes/vapour/spray. Avoid contact with skin, wear eye/face protection. Use only in well ventilated areas. Keep container tightly closed and in a well ventilated place. In case of contact with eyes, rinse with plenty of water.In event of irritation seek medical advice.   


STORAGE Ardex WPM 320 is sold in 20 litre plastic Pails. Shelf life is 12 months when stored in the original unopened container, in a dry place at 25oC. Do not store in direct sunlight. Replace lid tightly after use.   


Clean all equipment in fresh water immediately after use. Remove cured material with mineral turpentine or white spirits. Dispose of containers in compliance with all relevant local authorities, state, and federal regulations.
