VersiDrain 6P

VersiDrain 6P is a perforated interlocking plastic drainage sheet designed for use between the structural slab and sand or mortar screeds.

VersiDrain 6P under-screed drainage sheet is used in the construction of pedestrian walkways, plaza decks, balconies and verandas.

VersiDrain 6P creates a drainage and ventilation cavity that allows trapped water in the screed to escape via perforations and drainage channels in the sheet. This ensures that water and salts in the screed are prevented from migrating upward, to the surface to form unsightly efflorescence and algae.

VersiDrain 6P also acts as a separation layer and reduces tile and paver cracking caused by expansion of trapped water and movement of the structural slab.



VersiDrain 6P drainage sheets are used between the structural slab and sand or mortar screeds for:

  • Balconies and patios
  • Driveways and courtyards
  • Internal wet areas
  • Pool surrounds


Under-screed drainage sheets offers benefits including: Efficient under-screed drainage of tiles and paved areas Reduced surface cracking of tiles Minimised efflorescence and algae Protection of waterproofing membranes Support US LEEDS™ credits


VersiDrain 6P offers several unique features incorporating:

  • Interlocking panels that ensure stability and reduce product wastage
  • High compressive strength sheets (filled > 1,500 t/m²) that permit use under trafficable areas
  • Snap-on joining of large sheets that may be pre-assembled off-site
  • Sheets that enable simple and rapid installation with minimal operator training and tools required
  • Sheets that efficiently stack maximising transport economies


VersiDrain 6P is easy to install and minimises efflorescence and algae on tiles and pavers
