Why Basement Waterproofing Matters in Our Area

Asheville’s mix of mountain slopes, clay soil, and heavy rainfall means almost every basement faces moisture pressure at some point. Even minor leaks can cause mold growth, musty odors, and damage to stored belongings or finished walls.

Ignoring water issues doesn’t make them go away—it just gives them more time to spread. Our proven waterproofing systems are designed specifically for Western North Carolina basements, where hydrostatic pressure and poor exterior drainage are common. 

If your basement has ever leaked or flooded, then you need a quality basement waterproofing system. Without basement waterproofing, water problems never get better, they only get worse. Even if water leaks are uncommon, your home’s air quality can be impacted and your ability to finish your basement is restricted.

All kinds of activities contribute to polluting the indoor air we breathe. Surprisingly, mold spores & radon gases can be found in your own home, especially in your basement and crawlspace. In high enough concentrations, these pollutants can seriously harm you.

The Health Impact of Moisture

Moisture encourages mold, which can trigger allergies, asthma, and other respiratory issues. Because a large portion of your home’s air comes from your basement, waterproofing can significantly improve your overall air quality.

The average adult breathes over 3,000 gallons of air, 40%-50% of which comes from your basement or crawlspace every day. Children breathe in even more air per pound of body weight and are more susceptible to air pollution. Senior citizens are also more sensitive to air pollution because they often have heart or lung disease. People exposed to high enough levels of certain air pollutants may experience burning in their eyes, an irritated throat, or breathing difficulties. Long-term exposure to air pollution and radon gas can cause lung cancer.

Mold, fungus and other organic organisms can cause long-term damage to the human immune, neurological, reproductive, and respiratory systems.

Mold and mildew microorganisms are everywhere and will grow under certain conditions. An environment that has water (moisture) and organic material (food source) will accelerate the growth of mold. Mold will continue to grow if a moisture problem is left unaddressed and can emit toxic particles that travel through the air.

The best and most cost effective way to manage the growth of mold and mildew is to prevent water and moisture from getting into the basement and to control the humidity. Eliminating organic material (food source) or using mold resistant material will help, but the truth of the matter is that there are too many food sources in the basement to prevent mold from growing by eliminating just one. Mold will eventually grow on all surfaces. The only effective way to control mold is to control moisture and humidity. Basement & Radon Solutions installs and services a full line of self draining dehumidification products to handle all sizes of basements and crawl spaces.

Healthier for your family and your foundation.

The Basement & Radon Solutions Approach

At Basement & Radon solutions, we have spent years perfecting a closed drainage system that manages both water and air quality.  This system utilizes a wall vapor barrier to direct water down into the sub-floor drainage. Then, our powerful, patented sump pumps pump water out of the home.

Wall Vapor Barrier

A heavy-duty barrier covers the basement walls, sealing out moisture and directing it downward toward the drain system.

Sub-Floor Drainage Channel

Installed around the interior perimeter, our dual-chamber drainage system collects water from both the wall and the floor joint.

Sealed Sump Liner and Pump

Water flows into a sealed sump basin and is pumped safely outside—away from your foundation. You can add a battery backup for extra peace of mind during storms.

Together, these elements create a closed system that keeps your basement dry and your indoor air cleaner.

Why a Closed System is Better

Open drainage systems can release moisture and even increase radon levels. A closed system not only prevents water damage—it also helps protect your family’s health by reducing mold and gas infiltration. Radon testing is highly recommended after making waterproofing repairs to the foundation, slab or sealing/encapsulating a crawl space.

Signs You May Need Waterproofing

Damp Spots on Floors or Walls

Moisture seeping through your foundation can lead to mold, odors, and long-term damage. Stop dampness before it spreads with professional basement waterproofing.

Peeling Paint or Efflorescence

White, chalky residue or peeling paint means trapped moisture. Repainting won’t fix it—seal and waterproof your basement walls for lasting protection.

Musty Smells After Rain

That musty odor after it rains is a sign of hidden leaks or poor drainage. Eliminate moisture at the source for a fresh, dry basement.

Visible Mold or Mildew

Mold grows fast in damp basements and impacts air quality. Address the moisture problem now to protect your home and health.

Cracks Widening Over Time

Expanding foundation cracks let in water and weaken your structure. Seal and stabilize them before they cause major damage.

Rust on Appliances or Fixtures

Rust on pipes or appliances signals excess humidity. Waterproofing and dehumidification protect your home’s systems from costly corrosion.

If you notice any of these signs, schedule a free basement inspection right away.

Sump Pump Systems

Our sealed, airtight sump liner houses a high-performance pump with an optional battery backup to protect your basement during storms and power outages. The liner is installed to preserve your foundation’s integrity, and a dual float switch ensures the pump turns on exactly when it should—for reliable, automatic protection.

Your system also includes a properly sized exterior discharge line and drainage components that move water away from your foundation, working hand-in-hand with our interior drainage to keep your basement dry.
