The Steinodur PSN SD slab is used for foundations, basement walls and plinths, etc. On one side, the steinodur PSN slab has profiled drainage grooves for discharging groundwater into the drainage system. The other side of the board has embossed 2.0 x 2.0 mm grooves forming a fine square mesh for excellent plaster and adhesive adhesion. Each board has a rim on the periphery giving a reliable and tight connection without allowing thermal bridging.
