LASTRA 20mm by Atlas Concorde is the ideal solution for raised installation, in combination with polypropylene load-bearing supports. This application allows for the creation of an underfloor void of variable height between the footing plan and the substrate. This void space can house hydraulic pipes, cables and lighting systems. The spacers placed on the supports create an open joint of circa 3 mm between the slabs, therefore favouring the drainage of rainwater into the underlying gap.
