Tanking is referring to the use of a bonding substance that when applied correctly adheres to the exterior walls of your basement. This treatment is best when applied during the construction phase of building. When Tanking is properly applied, it will keep the basement dry permanently. Unfortunately, in many cases a home’s basement does leak after the Tanking process is applied. If the Tanking does not hold, this will cause the need for another type of sealant or process to keep water and dampness out of the basement.

Another choice for waterproofing a basement is called a cavity drainage system. During construction a plastic membrane is installed on the basement floor and walls. The floors are deliberately sloped during construction, allowing water to drain into a sump pump that is installed. A cavity drainage is an electrically operated system. Any power outages and the system stops working because of the electric sump pump. Another disadvantage with this type of waterproofing is that after a period of time the membrane itself may mold and mildew. At this point the membrane will need to be removed and another waterproofing system applied.

An exterior foundation drain, or sometimes referred to as a French drain, is the third type of a basement waterproofing system. Some builders and homeowners prefer this system and rate it as the best waterproofing choice of the three. This system operates by using a ground drainage system. When installed correctly, the drainage pipes divert water away from the foundation and basement walls keeping the interior of the basement dry.

Basement leaks and dampness can cause serious damage to a house. A wet basement devalues your home and can turn a potential buyer away when trying to sell. Many do-it-yourself people can tackle a wet basement with great success. Most home improvement stores also offer seminars for information and step by step instructions for waterproofing a basement without hiring a private contractor. When making a choice about the best waterproofing basement system make the best decision by being informed.
