"They did a real good job. They were real professional. We can now open the garage door from the inside of the house and now it is so smooth that we have to check to see if we hit the button to open it or close it.  Before we used to know when it was opening or closing because it used to make a noise. It helps when you move to a city where you are new. "

Basement Waterproofing questions, answered by experts

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.

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

French drains and yard grading systems are two highly effective ways to fix standing water around the foundation. Since the French drain uses a perforated pipe covered by gravel, you won’t have to worry about water taking the soil away from your foundation. Meanwhile, yard grading levels out the ground to prevent water from gathering around your foundation.
