Weplus 251

Vapour Release Mesh

Brief Description

Weplus 251 Vapour Release Mesh is a prefabricated, compression-resistant mesh for use on cementitious substrates. The mesh is bonded to the substrate. The special design of the mesh, featuring an even cavity structure, allows it to absorb the water vapour released by the substructure and remove this safely via outlets at the edges. When used as part of a system consisting of WestWood waterproofing products, it allows a high-quality, load-bearing and reliable waterproofing layer to be installed.


Composite material based on polymethyl methacrylate (PMMA)

RAL colours

Weplus 251
is available in the following standard colours:

RAL 7032 pebble grey


Weplus 251 Vapour Release Mesh is used on mineral substrates. The system is designed to avoid problems associated with vapour pressure and moisture, such as blistering and osmotic damage in the surfacing / waterproofing. The complete removal of the moist substructure can be avoided by installing the Weplus 251 system. This load-bearing system is used predominantly for balconies and terraces.

Properties and advantages

  • Refurbishment of concrete substrates
  • Decoupling and stress relief between the substrate and the build-up
  • A fully functioning waterproofing system is produced in conjunction with other, subsequently applied system components
  • Improved solid-borne sound insulation
  • Existing layers do not have to be removed completely
  • Reduced build-up height (complete build-up approx. 8 mm)
  • Water vapour generated is reliably removed
  • Rapid completion
  • High compressive strength
