For the correct raised installation of LASTRA 20mm, in case of flat surfaces, it is recommended to follow the instructions below:
1. PREPARATION OF THE SUBSTRATE AND INSTALLATION BED
Prepare a screed with inclination of 2% above the floor and apply a water-proofing layer to it. Spread a draining sheath allowing for the correct drainage of rain water checking its steadiness to bear loads and stresses undergone by the floor.
2. INSTALLATION OF POLYPROPYLENE SUPPORTS
Place the supports directly onto the draining layer
The joint between tiles is defined by the thickness of spacers at the top of the supports and is equal to 3mm.
VERTICAL EDGE CLIP
The vertical edge clip is a fixing system for outdoor raised floors that solves the problem of buffering of edges when there is no perimeter wall.
It consists of a couple of stainless steel clips that, thanks to a locking device, are anchored to the top and bottom part of supports. In this way a space is created to enable a section of LASTRA 20mm, duly cut to the correct size, to be inserted, obtaining a continuous surface between the edge and the foot plan.
