Technical Specifications

Screen or vapour barrier
Lay down STIFERITE’s Class B panel
(alternative: STIFERITE’s Class S – STIFERITE’s GT4)
Installation of waterproofing mantle made of two bituminous membranes minimum 4mm thick with reinforcement in TNT polyester in continuous strands. The second membrane must be made of an anti-root blend
Protective layer, drainage and filtering, small geo-composite mattress of ≥ 20mm thick.
Topsoil

Instructions and Guidelines
In order to guarantee a secure waterproofing seal and eventual maintenance to the finished package, it is of great importance to carefully design and install a perfect package.

For the purpose of identifying areas of accidental breakage of the waterproofing mantle, it is recommended that the roof is subdivided using small relief pads.
