How to Waterproof a Basement

An important task that has to be completed before the rainy season starts, is basement waterproofing. Accumulation of water is a common problem found in many households. The process of basement waterproofing employs different techniques to stop water from entering the basement. The activity of waterproofing includes various tasks such as sealing the leaks, closing the cracks, repairing holes, packing floor joints, etc.

Basement Waterproofing

Waterproofing the basement is the task of utmost importance in any household and especially in regions where there is a possibility of the water table rising. A rise in the water table leads to an increase in the hydrostatic pressure, thereby allowing water to enter through the cracks present in the foundation walls. The cracks develop due to the constant contraction and expansion of the wall joints of footing-foundation. Along with the above mentioned problems, decay, mold and other problems are also caused. Spalling is the process of deterioration of masonry surfaces, due to high levels of humidity and moisture.

The tasks to be carried out in the waterproofing other than applying paint and sealants, include installing gutters, drainage pipes, spouts, etc. Cleaning the debris surrounding these channels is also necessary in order to prevent clogging.

How to Waterproof a Basement

To prevent the entry of water into the basement, waterproofing should be done using the following methods.

Interior Water Drainage
It is the technique by which the negative effects of basement water are mitigated. The process is also called a basement waterproofing system. Basement waterproofing systems are implemented in the form of interior drainage systems. Most of these systems are patented by the Building Officials and Code Administrators (B.O.C.A). The main function of these systems is to drain the underground water along the foundation footers. The water is channeled through PVC pipes or a 'French Drain'. The sump pump system then removes the water from the basement.

Exterior Waterproofing
In the above mentioned interior water drainage, the water already present in the basement is removed. However, in exterior basement waterproofing, the water is prevented from entering the foundation walls of the basement. This technique stops the process of molding or wicking. Earlier, the process of waterproofing was not as effective and was all about damp-proofing the basement. Asphalt-based products were used as waterproofing materials. Nowadays, polymer products such as 'Tremco's Paraseal membrane' are used for the same. Polymer products last longer than the asphalt ones.

Other than the above mentioned solutions, one should also think about simple measures such as keeping the basement window open to reduce moisture. The increase in moisture is often marked with the presence of radon gas. To detect this gas, one can use an activated charcoal canister. Following the aforementioned techniques and procedures will definitely help in basement waterproofing.
