Drying a Wet Crawl Space in Nashville After a Storm

SERVPRO Dries Out Crawl Spaces and Offers Encapsulation to Prevent Future Water Damage from Storms

Nashville homes are usually storm resistant. People here are used to the wind and rain and act accordingly to protect their roofs, walls, and floors. It is more challenging to protect basements and crawlspaces from the same water, however.
 
To dry out a Nashville home wet crawlspace, we first have to remove the water. That is not usually a problem, but since this is a storm, the ground is going to be very wet and possibly damaged. SERVPRO technicians understand that means multiple, water-filled low spots. It can be difficult to bring in hoses even in a large crawl space to syphon out the pooling water.
 
The next step is to lower the humidity as much as possible. Bringing in a dehumidifier is not usually an option, just like pump hoses. We can set up dehumidifiers with flexible plastic conduits to direct the moist air from the space to the exterior. We can also place containers with chemical desiccants in the crawlspace to absorb water from the air. If possible, we set up an air mover above the crawlspace and blow in warm, dry air to displace the damp air we attempt to draw out using an exhaust fan.
 
Now that we removed the water, SERVPRO technicians encapsulate the crawlspace once the moisture level and soil dampness have been reduced to normal levels. We cover the dirt floor with polyethylene sheets and a polyester mesh for reinforcement. This 12 mil plastic guard covering prevents moisture from leeching up from the ground.
 
Next, SERVPRO technicians check the walls for cracks or seeps caused by the storm. Technicians can fill weaknesses with hydraulic cement and then cover the walls with masonry cement. These two compounds form an excellent seal against further water intrusion. Now that the walls are secure, we seal the polyethylene sheets and polyester mesh floor to them with waterproof, foundation tape.
 
Finally, to protect against further storms, we recommend applying a thick coat of liquid rubber to the outside of the foundation. Once it sets, the only way stormwater can get through is for a storm to crack the foundation or shift it underneath the home.
