Seepage of water from the roof or through the wall can cause damage to the building. Apart from this, the seepage of water can affect the aesthetic beauty of the building, and it can also affect the overall hygienic environment. Obviously, as soon as the seepage is noticed every effort should be made to plug the seepage. This can be effectively done by an innovative product namely the waterproofing membrane.
As experts point out, the concept of water proofing can be applied both to buildings and the cloth. But, the concept is normally deemed to be related to the construction industry. As the very name indicates, this technology of waterproofing involves covering the anticipated source of leakage with a thin cover also called as membrane.
The process of waterproofing has two main stages. In the first stage, an adhesive similar to tar is applied on the hard surface namely the roof. The second stage involves overlapping of the membrane on the adhesive. While spreading the membrane over the adhesive, it is appropriately heated using a gas burner.
Involves considerable labor:
According to construction engineers, installation of waterproofing membrane is a specialized job, and it involves a considerable amount of labor. On the other hand, they also point out that effectiveness of waterproofing is dependent on the choice of the membrane. A brief discussion on these and related issues is made here:
· The membrane you choose should be resistant to the UV rays of the sun. Experts point out that the waterproofing membrane should have elongation capability of up to 150%. In fact, there are membranes with more than 200% elongation capability. Experts suggest higher the elongation, higher will be efficiency of the membrane. This is because the membrane with higher elongation will be able to stretch over the cracks that may develop in the course of time.
· The membrane should be tear resistant. There are instances that membranes with higher elongation are prone to tear. Such membranes will not have good water resistant capability.
· Similarly, the membrane should be resistant to oil, petroleum and also to microbes. Further, the membrane should have good load bearing capability. Experts further suggest that the membrane should be resistant to punctures and should have anti slip properties. It should have a high-tensile strength so as to withstand foot traffic.
Application over cloth:
As far as waterproofing of cloth is concerned, the adhesive is first applied over the cloth. Thereafter, over the adhesive a very thin layer of membrane is fixed. Over this membrane, another coat of adhesive is applied and over it another layer of cloth is fixed. Thereby the membrane gets sandwiched between two layers of cloth.
There are exclusive waterproofing processes for both interior and exterior walls with varying procedures. Construction experts suggest that waterproofing procedure could be adopted for basements, retaining walls, shower recess, ponds and swimming pools and in such other places. Naturally, a good quality waterproofing will enhance the life of the building. The membranes are available in several colors, shades and thickness. They are available at an affordable price tag. Experts are of the opinion this waterproofing procedure can be applied to both old and new constructions.
