A method of flood protection of buildings with three key components: hydrophobising impregnation 18 of the external walls 1using a water resistant chemical which retains the permeability of the substrate to which it is applied, without altering the appearance of the treated walls; installing a cavity drainage membrane 13 on the floor and internal walls of the building; installing a perimeter floor drainage system 4 with adjustable pivotally connected corners and T-pieces, and a deflector to aid water flow along channels. Additionally, the drain may be ventilated either by a mechanical fan or passive stack ventilation, to evaporate moisture and to aid in the removal of harmful gases such as radon. The extract ventilation may be linked to the sump pump. |
