Foundation Waterproofing

foundation waterproofing - External Foundation WaterproofingThere are two types of foundation waterproofing: internal and external. Internal waterproofing is a solution that’s installed inside the home’s crawl space or basement. On the other hand, external waterproofing involves installing a barrier on the foundation’s exterior.

External waterproofing typically occurs while the home is being built. Furthermore, this falls into two categories: damp proofing and waterproofing.

Foundation Waterproofing – Damp Proofing vs. Waterproofing

Damp Proofing

In general, damp proofing is a spray that’s applied to the foundation. It doesn’t waterproof the foundation, but it helps limit the water that soaks through the foundation. Damp proofing a foundation is now common practice when a home is being built, but isn’t enough to prevent water problems.

 

Waterproofing

Waterproofing involves installing a layer or membrane over the foundation, which prevents water from entering the foundation. This is typically followed with the installation of an exterior drain tile, also known as an exterior footing drain, to help move water away from the foundation.

Installing an external waterproofing system, after a home has been built, can damage the foundation. Also, costs can rise up to 50% more than an interior system.

Excavation runs the risk of damaging the foundation, and once the soil is removed, so is the extra support it provides. Cracks and other structural problems could form, which can lead to expensive repairs. If you’re experiencing water problems, the safest option is to install an interior waterproofing system.

Crawl Space Waterproofing vs. Basement Waterproofing

In particular, the type of waterproofing you need is dependent upon the type of foundation your home is built on. Crawl spaces are encapsulated, which involves completely separating the crawl space from outside elements and the dirt floor.

Basement Waterproofing Solutions:

Basement waterproofing can involve a below-floor drainage system, coupled with a sump pump and wall system. For example, if the waterproofing problem is caused by a foundation crack, a foundation repair expert will need to be consulted. Surprisingly, many homeowners wait to contact an expert until the damage becomes substantial.
