Treatment of Basements
To ensure the dryness, the overall of the structure below ground level should be given with a continuous membrane of asphalt (i.e. DPC) either mastic asphalt or bituminous felt supported on the inside. This is achieved through spreading a layer of an impervious material (i.e. DPC) over the all area of the floor and continuing the similar by the horizontal walls extending vertically up, creating a sort of water proof tank as display in Figure.
