Design requirements
ARDEX WPM 3000X (Shelterseal 3000X) waterproofing membrane can be used over various substrates including:
- concretes, renders, screeds
- fibre cement sheets
- structural or marine plywood
- polystyrene blocks
Typical applications of ARDEX WPM 3000X include, but are not limited to, planter boxes, foundations, below-ground applications and retaining walls.
Installation requirements
Surfaces to which the ARDEX WPM 3000X (Shelterseal 3000X) systems are installed must be properly prepared prior to installation. All surfaces must be clean, dry, smooth, free of sharp edges, loose or foreign materials, oil, grease, and other materials that may damage the membrane. If concrete has moisture on surface use gas torch to dry and warm before priming.
Prior to the application of the membrane all prepared surfaces (except polystyrene blocks) should be primed with ARDEX WPM 240 (shelter Primer) at a rate of 5-6m² per litre and allowed to dry.
Maintenance requirements
Starting at the lowest point, the membrane must be installed in accordance with the Technical Literature.
Sheet edges must be overlapped a minimum of 60mm as marked on the sheets. End laps must be a minimum of 100mm, with upper sheets lapped over lower sheets. Internal and external corners of single layer systems must be reinforced with an extra layer of membrane 300mm wide. Where two layer systems are specified lap joints must be staggered. Protection material must be installed before backfilling. Backfilling must commence immediately after the membrane is installed to ensure the membrane is not left exposed to sunlight or UV radiation.
Installation of the membranes must be completed by tradespersons who have experience in the application of self-adhesive membranes.
