Methods for Foundation Waterproofing and Stopping Foundation Leaks
Methods for Foundation Waterproofing – Prevent Foundation Leaks & Slab Leaks

Undeniably, one clear solution to a foundation leak under a house is foundation waterproofing.

However, it can be hard to find a way of successfully keeping underground water from finding its way through a foundation. In many North Carolina homes, these troublesome leaks pop up where a basement floor and a concrete foundation wall meet.

Foundation leaks lead to a variety of problems. The most common include mold, mildew, and effervescence on concrete in basements, undermining of foundation beams, and damage to the structure of the house if it settles.

Finding the actual problem where the water leak is coming from can be difficult. It’s important to realize, selecting the right contractor with plenty of experience in detecting water leaks. Additionally, a water leak specialist that is also knowledgeable in how to stop underground water leaks from damaging your home.

Successful Foundation Waterproofing

Each home is different when it comes to a foundation leak and the best foundation waterproofing method. An experienced contractor starts by carefully assessing the problem and then choosing repair methods and products to match the situation.

There are several strategies for keeping water out of a basement or from running under a house, including:

Grading the landscape to slope away from the building
Installing gutters, downspouts, and drainage pipes
Building a French drain
Installing window-well covers on basement windows
Coating the foundation interior or exterior with paint or a sealer product
Filling cracks and holes with a filler product
Installing a sump pump to remove groundwater

Grading

Obviously, proper grading around the exterior of the house is something the original builder should do. However, this doesn’t always happen. A resurfacing of the landscape around a home may be necessary to keep water away from the foundation.

When it’s not possible to fix grading problems around the house to redirect water, contractors often install a sump pump.

Gutters and Downspouts

A well-designed gutter and downspout system is crucial for keeping water from resulting in a foundation leak. It’s also essential to install buried drainage pipes connected to the ends of the downspouts, leading water away from the building.

French Drains and Exterior Foundation Sealing

French drains are placed on the outside of the foundation. First, a trench is dug along the side of the house down to the bottom of the footing.

A drainage pipe is then placed at the bottom of the trench, and the trench is backfilled with gravel. The drain pipe must lead water away from the house and deposit it into a storm drain or natural drainage.

While the concrete footing is exposed, contractors often seal it with a paint-on sealant product or a water-proof sheet membrane.

French drains as well as exterior foundation waterproofing are excellent prep work to stay one step ahead of possible concrete slab water leaks. A little prep could ultimately save you thousands. If your home or business has not yet had any foundation waterproofing services, it’s never too late to consider. Protect your investment as best you can from a dreaded concrete slab leak or basement wall or window leak. Water can seep in your foundation from just about anywhere if left unprotected.

Window-Well Covers

Window well covers come in all sorts of shapes and sizes. They cover the window well on basement windows, keeping rainwater from collecting in the well. Covers are see-through, so they don’t block much light.

Paint-On Foundation Sealing Products

There are dozens of latex and oil paints, primers, and foundation sealing products on the market. Most of these products must be applied to the bare concrete, and you need to remove any old paint first.

You can apply foundation sealing products to the exterior or interior of the concrete once it has been adequately cleaned and prepared. However, these products often fail eventually, unless you first solve drainage problems on the outside of the house.

Foundation Crack Sealers

Depending on the size and location of a crack or hole in a foundation, applying an epoxy or polyurethane filler can often fix the problem. Many polyurethane fillers expand when they come into contact with water, making them especially useful in wet areas.

Installing a Sump Pump

If the source of water on the outside of the house cannot be stopped, a solution is installing a sump pump. The pump sits in a concrete or plastic basin below the slab or foundation.

Water collects in the basin, and the pump comes on automatically when the basin starts to fill. A pipe then leads water out to the street or another suitable location.
