Old Homes Need Your Care

Often we see dampness on the internal walls of Old, Aged houses and associate it to weakening of the strength and impermeability of plaster on the wall. While the reason is true there is no reason to believe that nothing much can be done about it by way of internal wall waterproofing.

There are many causes for the appearance of damp patches on the internal walls. It is very important to diagnose the source before an appropriate solution is found for the problem, or internal wall waterproofing services (repair & renovate) are sought. For old homes there may be projecting or overhanging Eaves or more commonly known as “Chajja” in Hindi, (more like an external Sun Shade, generally over the windows).

There are rainwater drip channels or edges on the underside of the “chajja’, on the outer edge. There are rainwater channels, also known as drip edges, normally present on windowsills, parapet, and edges of roofs and balconies of older buildings. In the pre-water repellant paint days, the obvious function of these rainwater drip channels or drip edges was to keep rainwater away from the walls.

Over a period of years, due to repeated painting of the exterior of the buildings, these channels or the groove along the drip edges loses its continuity, rendering it ineffective. As result rainwater flows along the wall and if the external wall is not painted using water repellant paints it tends to seep through towards the internal wall. This condition calls for engaging internal wall waterproofing services (repair & renovate) for internal wall waterproofing.

Old buildings are different from the modern, new buildings. New modern buildings are designed to keep moisture out using the self-protective barrier system, whereas older buildings have ventilators to allow circulation of air. There are times when there is condensation on the internal walls causing dampness due to improper ventilation.

There are times when the damp rises on the interior walls from below, in the ground level floor of the old house. There could be cracks and gaps in the exterior walls which causes damp to penetrate inside. At times there may be gaps between the window frame and the masonry work that leads to damp internal walls. All these, in the long run, causes heavy damage and thus it requires proper internal wall waterproofing and when the matter goes out of hand it demands internal wall waterproofing services (repair & renovate) to be taken up urgently.

Whatever be the cause there are appropriate internal wall waterproofing solutions like exterior wall coating, silicone materials being injected for rising damp, use of polymer modified pastes for sealing wall cracks or polymer-modified sealants for sealing gaps.
