The truth about basement waterproofing

The truth about basement waterproofing is that all homes can benefit from the added protection that basement waterproofing provides. Its also a solution for a leaking basement. Whether or not you have a block, stone, or concrete foundation, you can benefit from basement waterproofing. The only draw back when having a stone or block foundation is you cannot have a crack injection.

Crack injections are inexpensive way to waterproof cracked foundation walls; however only concrete can be injected. There are two types of crack injections, epoxy and polyurethane. Epoxy is the prefered choice for most home owners as the epoxy resin adds structural strength to the cracked foundation wall. The problem with epoxy that makes polyurethane more attractive is that epoxy has to be injected into a dry crack only while polyurethane can be injected into a wet crack. Both injections are basically the same price. It's just a question of desperation, patience, and necessity.

There are a few methods or repair and prevention that you should be aware of. One is the already mentioned concrete crack injection, second is the interior drainage system, and the third is the exterior excavation and basement waterproofing weeping tile system..

Interior drainage systems are the second most expensive basement waterproofing method used by experts in the field. This involves breaking up the concrete floor 6 inches from the wall alongside it and trenching until you get to the footing then place weeping tile alongside the footing. The weeping tile is installed and runs under the floor to the sump pump or floor drain. Black dimple board is installed on the wall beside the trench. Then the weeping tile is covered with gravel and concrete is repaved over top. This allows for water that penetrated the foundation to run into the weeping tile under the floor and into a sump pump or floor drain.

Exterior basement waterproofing weeping tile systems is the most expensive basement waterproofing solution and involves excavating the ground beside the foundation all the way to the footing. A wall treatment is used on the foundation to prevent water from penetrating. Then weeping tile is placed beside the footing and gravel poured on top. Then the excavation site is back filled. It is common to have high spots of ground after the job is done. This is because the ground needs to settle a bit.
