Kontract mesh - Cavity drainage membrane with a mesh lathing suitable for plasters/screeds

Description

Kontract Mesh is a high density polyethylene membrane incorporating 8 mm studs which allows the isolation of wet walls above and below ground. Incorporates a tough HDPE mesh lathing welded to the front face to allow the direct application of various plaster finishes or adhesive ‘dabs' and plasterboard. Also suitable for use on floors above ground to be screeded or in conjunction with Kontract 8 below ground.

Note: in basements where the walls are particularly wet (running water) we recommend the use of Kontract 8 on walls and floors (see separate data sheet).

• Stud height 8 mm, drainage volume 5.5 litres/m2
• Sheet thickness 600 _m, density 0.7 kg/m2
• Excellent low and high temperature stability
• 150 kN/m2 load bearing capacity
• High durability and water resistance

Kontract Mesh is suitable for use in accordance with BS 8102:1990 to provide Type ‘C' drained protection to structures below ground giving a Grade 3 or 4 dry environment suitable for domestic or commercial use. In basements it is essential that Kontract Mesh is used in conjunction with a suitable sump and pump facility (unless passive drainage is available on one side of the building) and that this is maintained throughout the lifetime of the installation. To control the risk of condensation it is recommended that all basements should be provided with mechanical ventilation to ensure adequate air circulation in accordance with the guidelines in Approved Document F (Building Regulations 2005).
