Asheville homes face water problems from mountain runoff and clay soil. When it rains, water runs down from the mountains. Clay soil soaks up water and pushes against your foundation walls. This can crack your walls and flood your basement.
Exterior waterproofing stops water before it gets inside. We dig around your foundation and put waterproof coatings on the outside walls. Then we add drains that carry water away from your house. Most jobs take 3-5 days. We work all year to keep Asheville basements dry.
This method costs more than fixing leaks from inside. But it fixes the real problem. Water that never touches your foundation can’t crack it or leak through Learn more about waterproofing services in Asheville
What is exterior basement waterproofing in Asheville NC?
Exterior basement waterproofing keeps mountain rain and groundwater out of your basement. We dig around your foundation, put on waterproof coatings, and add drains before filling the dirt back in.
Here’s what we do:
- Dig around your foundation to expose the walls – We dig 6-8 feet deep so we can reach all the way down
- Put waterproof coating on the walls – We spray or roll on thick coatings that stop water from soaking into concrete
- Install drains to move water away – We put pipes in gravel beds that catch water and carry it away from your house
Mountain storms and clay soil in Asheville create lots of water. Outside waterproofing handles this water better than inside fixes.
Foundation Water Damage Starts Outside Your Asheville Home
Water rolls downhill toward homes in Asheville’s hilly areas. Heavy rains in the mountains send lots of water toward houses in Montford and West Asheville. Wet soil pushes hard against your basement walls.
This pushing causes cracks, bent walls, and leaks through concrete. Fixing leaks from inside only treats what you can see. Water still attacks your foundation from outside. Exterior waterproofing removes water before it causes trouble. This stops the real problem instead of just hiding damage.
Excavation Exposes Foundation Walls for Complete Protection
We mark where pipes and wires are before we dig. Asheville has rocky mountain soil. We use special digging machines that won’t hurt your foundation or break underground lines. We dig 6-8 feet deep holes around your whole foundation.
This lets us see all of your basement walls. We clean the walls and fix any cracks we find. The wide hole gives us space to add drains and fill dirt back in. People in Kenilworth and North Asheville worry about their yards. Digging around the whole foundation lets us check everything, add waterproof coatings, and put in drains that work.
Waterproof Membranes Block Water from Entering Foundation Walls
We spray or roll waterproof coatings on your clean walls. These rubber or plastic coatings seal up concrete and fill small holes. Asheville’s cold winters and hot summers need coatings that bend without breaking.
We put drain boards over the coatings. These boards help water flow down. We add several coating layers so there are no gaps. The materials stop tree roots and chemicals in dirt. This makes a wall that water can’t get through. The coating stops water from soaking into your foundation.
Footer Drains Redirect Mountain Runoff Away from Your Foundation
We put pipes with holes in them at the bottom of your foundation. These pipes catch water before it touches your walls. Gravel around the pipes lets water flow easily. Special fabric keeps dirt from blocking the holes.
The pipes tilt away from your house toward lower ground. Asheville’s mountain slopes let water flow downhill on its own. You don’t need pumps in most places. Homes in Biltmore Forest and South Asheville get puddles by their foundations when it storms. Our drains catch this water and move it away before it can push on your walls.
