Water discharge or additional unconditionally wet ingress in buildings results in damp, uncomfortable internal environments; deterioration of internal finishes (including mold growth); unpleasant damp areas on wall and ceiling surfaces and multiplied concentrations of harmful pollutants moving occupant's health. The exclusion of wet from buildings is thus not solely fascinating however conjointly AN utmost concern to the residents of the buildings.

Water seepage through external walls

Building envelopes should, therefore, be adequately designed and made to stop the ingress of water.

General reasons for water seepage through external walls:

1.Joints and cracks in the walls
2.Absorption and permeation of the materials
3.Construction joints in the walls
4.Penetrating dampness
5.Rising dampness due to capillary action
6.Poor construction practices
7.Honeycomb structures in concrete or plaster.
8.Separation gaps

Waterproofing Systems & Materials

Water tightness of external walls is typically achieved by providing adequate wall thickness, correct coming up with at construction joints, and surface rendering and finishes that function as barrier against water ingress. Generally, no consideration is paid towards significant regions like partition holes, honeycomb zones, sodden verification courses at the platform level, etc. This results in serious leakages through external walls and damages to high-priced internal paints & finishing.
