Water in a crawl space or basement is an alarming concern because it can indicate a bigger issue. Eventually, it can create structural problems like damage to the foundation walls. Most importantly, wet ground can lead to mold growth and wood rot – which is a health risk and no one wants that problem at home. The air quality in a home is significantly compromised if there is any water intrusion, mold or mildew growth or something else.

Crawl space waterproofing is the best option for keeping your home free of moisture problems and the damage caused by water leakage or humidity. Waterproofing makes buildings more energy-efficient, meaning lower energy costs, and protects against expensive work like foundation repair or new construction costs later down the road.

The best part? There’s nothing you need to do after it’s installed; just make sure there are no leaks or cracks around your home. That way, your house stays dry and protected for as long as possible.

How Do I Know If My Crawl Space Needs Waterproofing?

A few telltale signs indicate that your crawl space may require this type of protection. Here are some of the most common ones:

  • Standing water
  • Deteriorated insulation
  • Musty odors
  • Lack of vapor barrier
  • Uneven dirt floor
  • Freezing floors
  • Bumpy/soft floors
  • Moist foundation blocks

These conditions could be signs of crawl space water issues. If any of these problem exist in your home, it’s time to have your crawl space waterproofed. Call us today to schedule a consultation with the experts at DryTech Waterproofing.

Crawl Space Basement Waterproofing Solutions

If your crawl space needs waterproofing, DryTech Waterproofing can create a custom solution that meets all of your needs. Our crawl space waterproofing solutions include:

Perimeter Drainage System: A DryTech-installed perforated drain pipe along the perimeter of your crawl space will prevent rainwater from getting inside your home.

Sump Pumps: A sump pump placed near the lowest point in the crawl space can remove any standing water that accumulates. They can also help reduce the amount of moisture entering the crawl space floor.

Crawl Space Encapsulation Systems: Using a DryTech installed WhiteCap Encapsulation system, you can eliminate cold floors, reduce high utility bills, and create a moisture barrier between the crawl space and ceiling joists.

Drainage Matting: To help water flow away from your home’s foundation, we can install drainage mats under the slab. These mats create an air gap to let water accumulate and flow away.

Crawl Space Wood Repair: Wood destroying insects, like termites, feed on wood, causing the wood to rot and decay. To prevent this, we repair existing wood then add a protective coating.

Crawl Space Insulation: DryTech installed foam board and spray foam insulation help regulate the temperature within your home. Proper insulation in crawl space walls and floors will decrease the energy consumption of heating and cooling systems.

Dehumidifier: Dehumidifiers dry out a damp crawl space and automatically maintain a pre-set humidity level. By controlling crawl space humidity, you can create a hostile environment for mold and mildew. You can also alleviate allergy symptoms with a dehumidifier.

Mold Growth? Excessive Moisture? Bad Odors?

In the East Tennessee area, excessive moisture in a crawl space can lead to mold growth. Even when no standing water is present, a crawl space can still have excessive moisture due to a few different factors. One of these being that your crawl space has a dirt floor from which moisture is constantly escaping into the crawl space. Crawl space vents can also add unwanted moisture to the crawl space by allowing high humidity air from outdoors into your crawl space. Because the natural air flow process of all homes is from bottom to top (known as the stack effect) this unwanted moisture moves up into the structural components and eventually into the living areas of your home, bringing with it mold spores, dust mites, and bad odors. Contact DryTech today at (865) 410-1077 for professional help with your mold growth problem!

Foundation Repair

Ignoring foundation problems can result in expensive repairs or loss in home value in the future. DryTech uses warrantied products to repair foundations, ensuring the integrity and safety of your home.

Indicators of foundation problems can include:

  • Bowing, buckling, or cracking walls
  • Diagonal cracking of poured concrete foundation walls
  • Uneven floors and floor creaking
  • Sagging crawl space
  • Wet Basement or crawl space

DryTech will assess your foundation damage and recommend the best solution. Many times, water pressure is the cause of foundation issues. Freezing water in the ground, lack of waterproofing, tree roots, and aging can all contribute to bowing or cracking walls. Steel I-beams installed and bolted to floor joists are often the best option for bowing walls. I-beams prevent further foundation damage. Concrete leveling and crawl space jacks are frequently recommended as well. Whatever situation you find in your home, contact DryTech to stabilize your foundation. We have the expertise to fix it! Call (865) 410-1077 today!


The crawl space beneath your home is vulnerable to high humidity which can lead to mold problems, pest infestations, structural damage, and even allergy symptoms for you and your family. A dehumidifier is a great solution for controlling humidity in your crawl space or cellar and prevents excess moisture from entering your main living area. Let DryTech install a whole-home humidifier in your home and feel the effects of properly humidified air! (865) 410-1077.
