Whether the rain water enters into the walls?
Normally, the water coming from outside comes through the capillaries, created over a period of time and these capillaries will again bring water during rains. But, since in Negative Water Proofing system, the capillary is sealed, water will not be able to penetrate in the walls and where the weather is hot and it not rainy; the capillary is again emptied of water through evaporation. Some times, people ask, if there is a heavy rain, then weather the water will go. This can be better understood by giving an example of any object, like a Handkerchief. If there is water and we put the Handkerchief, then to an extent this will be absorbed. But excess water will flow. Similarly, in case of walls, excess water will flow over the walls in normal course and go to the drains. To explain it in a still simple way, every porous object has moisture taking capacity depending on the porosity of the mass and once the pores are filled up, then excess water will flow out.
