Interlocking concrete paving blocks can be laid on a crushed sand/gravel bed above a separation sheet and FLOORMATE™ 700-A boards. Up to a weight of 3.5 tons of cars, a load distribution slab is not required above the insulation. At low intensity traffic or limited grade loads FLOORMATE 500-A boards may also be sufficient. For intensive traffic and heavyweight vehicles a load distribution reinforced concrete slab must be installed on a min. 3 cm 4/8 mm crushed gravel bed above a separation sheet and the FLOORMATE 500-A or FLOORMATE 700-A insulation.
