Foundation waterproofing is a proactive rather than a reactive way to ensure that you have a dry basement. Ideally it is done while a house is being built, but exterior foundation waterproofing can be undertaken with any basement, whether it is a basement of poured concrete or one of masonry block walls. The experts at Dryworx can guide you through the process your specific basement needs.
Why Would Exterior Foundation Waterproofing Be Needed?
Wet basements happen because of water in the surrounding soil finding its way through cracks and porous parts of the basement wall. Concrete walls can have spots that allow water to seep through due to problems when the concrete walls were poured, and masonry block walls can develop cracks along mortar joints.
The type of soil also affects water getting through to your basement, too. Soil absorbs moisture and expands; the degree of that expansion differs with the kind of soil. The soil that is common in much of the area absorbs a lot of water, expands a great deal, and drains poorly. All this expansion and swelling creates pressure around the foundation and that pressure can force water through any small opening.
What Is Exterior Foundation Waterproofing?
Exterior basement waterproofing can deal with all of these issues. The basic method involves excavating the soil away from the external basement wall, installing the appropriate waterproofing membrane, installing a drainage system and filling the surrounding area with gravel. A sump pump may or may not be be necessary. The basement wall may need some prep work, and the waterproofing membrane can differ; the certified experts at Dryworx will be able to tell you precisely which elastomeric waterproofing membrane will work best for your basement. The gravel fill is especially important given the kind of soil in our area.
What Are the Benefits of Exterior Foundation Waterproofing?
The benefits of exterior foundation waterproofing are significant. It prevents water from entering your basement rather than managing water that has already gotten in. It directs water to the exterior drainage system, away from your foundation. The gravel relieves the hydrostatic pressure that can otherwise build up. Most importantly, it gives you a dry basement. Having an exterior foundation waterproofing system means the elimination not only of seepage or wet spots, but of nasty musty odors as well, so your basement becomes usable living space.
