ARDEX WPM 1500 is normally used as a single layer membrane in horizontal or vertical applications for waterproofing in below ground applications. It is primarily applied to the outside of a sub-structure of a building, such as a foundation or basement, to prevent water ingress or as a gas barrier to prevent the ingress of toxic gases.

ARDEX WPM 1500 can also be used in other applications including: 

• Under floor slabs
• Behind masonry walls
• The lining of substrates of in-situ or precast concrete
• Retaining walls
• Lift shafts
• Tunnels

ARDEX WPM 1500 can also be used in combination with other ARDEX WeldTec products. ARDEX WPM 1500 may be used in various combinations to produce a variety of specifications tailored to suit the individual waterproofing needs.

• ARDEX WPM 1500 must be protected from UV once installed. Maximum exposure should not exceed 60 days
• Not suitable as a trafficable surface
• Must be installed to the ARDEX technical literature
• Must be installed by an ARDEX approved installer
• Construction joints must be adequately detailed
• Top edge must be terminated mechanically and sealed

• B2 DURABILITY: Performance B2.3.1(a) Not less than 50 Years ARDEX WPM 1500 is a suitable material for tanking (Butyl) and is expected to have a minimum life of 50 years provided it is installed in accordance with the technical literature.
• E2 EXTERNAL MOISTURE: Performance E2.3.3 Walls, floors, and structural elements in contact with, or in close proximity to, the ground must not absorb or transmit moisture in quantities that could cause undue dampness, damage to building elements, or both.
  ARDEX WPM 1500 is considered impervious and has been independently verified to have a vapour flow resistance greater than 1700 MN s/g NZS 3604:2011 and NZS 4229:2013 require DPMs to have a vapour flow resistance of no less than 90 MN s/g

• F2 HAZARDOUS BUILDING MATERIALS: Performance F2.3.1 Materials must not present a health risk to people. ARDEX WPM 1500 is inert and meets this requirement. Note: Basement designs solutions must be considered and alternative solutions- they are not covered by NZBC E2/AS1
