It can be placed on the extruded polystyrene insulation, whatever its thickness, or directly on the waterproofing by previously placing a separating layer using a geotextile. It is composed of limestone aggregate (also available with silica aggregate) with a 3 / 6mm grain size, cement, water and different additives to give consistency to the mixture; as long-acting superplasticizers, cohesives for concrete and stabilizers to facilitate pumping. Depending on the dosages of the mixture, compressive strengths can be achieved that allow from an occasional transit of the roof, to road traffic.

In this way the waterproofing is not damaged and its already excellent drainage capacity is improved. A minimum thickness of 5 cm is recommended.
