Bitumen-based waterproofing applied by machine and by hand
How to carry out structural waterproofing to protect against ground dampness and non-accumulating seepage water is regulated in part 4 of DIN 18195. Since any type of soil can absorb and store moisture, ground dampness must always be regarded as the minimum load scenario. The ground below grade and the fill material must be pervious to such a degree (water permeability coefficient k≥ 10-4 m/s) that any water occurring in liquid form can trickle from the ground grade edge right down to the free groundwater without a problem.
Even after heavy downpours no water must accumulate near the waterproofing.
However, if in the case of less pervious grounds (Water permeability coefficient k < 10-4 m/s) a drainage is installed in accordance with DIN 4095, the waterproofing may also be carried out in accordance with load scenario 4. However, in this case, too, water must never accumulate near the waterproofing and exert pressure onto it.
