Defects caused by dampness in buildings
In this construction article, you will be familiar with various causes of dampness in buildings.
Dampness happens because of the existence of moisture in buildings in various parts like a floor, wall, roof etc.
The dampness in the building results in creating distasteful and unhealthy conditions to inhabitants. To get rid of such circumstances, proper preventive measures for dampness in buildings should be undertaken.
The rain water, groundwater and leakages from pipes are some of the main contributors to dampness.
Rain water
Rain water may penetrate the building’s because the rooftop is not perfectly covered with waterproofing materials.
Faulty slopes to roof
In the flat roof, faulty roof slopes leads to the pooling of water and for this reason dampness occurs.
From wall top
If the top of the wall is not safeguarded with the impenetrable layers like concrete etc the water can penetrate the building with ease.
From exterior wall
The spattering of rain on the outside surface of the building also cause penetration of water to the wall. Besides, imperfect plastering on the outside surface may also cause dampness.
Fixing of drain pipes inappropriately
If the drain pipes from the roof top are not secured perfectly, water clogging happens adjacent to the mouth of the drain pipes and thus dampness is created.
Faulty construction of joints
Faulty slopes in sunshades, inappropriate wall joints as well as construction joints in roof etc leads to formation of dampness.
Groundwater
Normally the buildings are built upon the soil, because of capillary action or surge in the groundwater table, the water may hit the foundation. It results in development of dampness at the floor level.
In commercial or residential building, there are several water pipes, soil pipes etc. These pipes are attached to distribute the water or discharge the water. The network of the pipe is formed by connecting a number of pipes bends etc which often cause leakages of waters The leakage of water leads to the dampness in buildings.
