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.
