"The owner (Michel Bervaldi) was very informative and forthcoming re the project. Unfortunately, financial priorities did not allow us to follow though without the project. We did speak with other contractors and Michel would have been our first choice if we were to proceed as originally planned."

Basement Waterproofing FAQs, answered by experts

No, you don’t want your crawl space to be wet because water and even moisture in the air under your home can attract insects and rodents, decrease your indoor air quality, increase your energy bills, promote mold growth, and even lead to structural damage. If you notice any signs of water or humidity in your crawl space, you should get the issues addressed immediately by contacting a professional. They can remove moisture and will know how to waterproof your basement to prevent ongoing problems.

Yes, engineers assess soil load-bearing capacity and provide construction guidelines.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.
