What Causes a Wet Basement?

There are several potential causes of a damp basement.

Identifying a wet basement is simple, as a musty smell, unusual wall stains, water seepage, and furniture damage accompany it. Our solution is to waterproof both walls and floors to prevent such issues.

Exterior Basement Waterproofing Methods

Basement waterproofing doesn’t happen exclusively indoors. We can also employ outdoor methods to ensure water stays outside and away from the house.

Waterproofing Foundation Walls

A common way to prevent dampness in a building is to apply asphalt to the exterior foundation wall using brushing, rolling, or spraying techniques.

Heavy rolls of impermeable material are glued to the structure’s exterior to waterproof a building. Seams are lapped to seal out moisture.

The material used for waterproofing foundations is sprayed on and has the same thickness as solid materials. It is an elastic coating similar to liquid rubber and requires several layers to achieve the desired thickness. This technique is effective in preventing expensive foundation repairs and damage to exterior walls.

Adding Downspouts and Gutters

To prevent water from collecting around the house and seeping into the cellar, downspouts are attached to gutters to carry water away from the house.

Rainwater saturation of the soil around the foundation can cause hydrostatic pressure, leading to water seeping through walls, floor joints, and cracks.

It’s important to manage rainwater runoff to prevent basement flooding by installing gutters and downspouts. Ensure water from the downspouts is directed at least six feet away from the building’s foundation to keep it from seeping into the basement.

Interior Basement Waterproofing Methods

One of the main components of basement waterproofing services is the use of various methods to waterproof the interior of the basement.

Installing Sump Pumps

The purpose of a sump pump is to prevent flooding and structural damage by removing water from a specific basin located at the lowest point in the basement floor.

Furthermore, they can be combined with other waterproofing techniques, like building a drainage system around the exterior of the basement, to provide unbeatable protection against water penetration.

It’s wise to consult with professional contractors specializing in basement waterproofing. At Capstone Waterproofing Solutions, we can assess your specific needs and provide you with guidance on what steps to take.

We’re experts in sump pumps and could advise you on what works best for your situation.

Adding Interior Foundation Coatings

Applying waterproof paint or epoxy coatings to the interior walls is effective to prevent water vapor from seeping through the walls of a basement. This is especially helpful in areas that experience high humidity or wetness.

Before installing interior coatings, it is crucial to fix any foundation cracks.

Other waterproofing techniques, such as installing a sump pump system and ensuring adequate drainage, can be used in tandem with internal foundation coatings to give the best possible defense against water intrusion.

Consulting with basement waterproofing contractors can help to determine the best course of action.

Frequently Asked Questions

The process of waterproofing a basement starts with a comprehensive inspection to identify any signs of seepage. This includes looking for water coming from the bottom of the wall, around the baseboards and in the cove area where the wall and floor meet.

Stains on the wall, especially higher up, can indicate issues with the window well or cracks in the foundation. The outside of the building is also inspected to determine the source of water pressure, such as incorrectly-installed downspouts.

To waterproof your basement, the first step is to remove the drywall around the affected areas.

We then carefully jackhammer the floor to reach the bottom of the footer, where the house is stabilized. We grade the footer to ensure a 1-inch drop every 10 feet and install filters to prevent water infiltration. We add gravel around the pipe to keep mud from the pipe and filters, them install drainboards on the walls.

Finally, we apply concrete to the floor to complete the waterproofing process. This process typically takes up to 5 days for a space of 200 linear feet, but most basements in Maryland are around 100 linear feet.

Yes, with the right tools and techniques, we can waterproof your basement effectively and efficiently, even if it has already been finished. In most cases, it requires tearing up the damaged portion of the drywall, usually 2 feet up from the floor line. This approach allows us to access the areas that need to be waterproofed while minimizing the disruption to your finished basement space.

Several factors may contribute to a basement waterproofing issue. Cracks in the foundation and water seepage are two of the most common causes of these problems. It only takes 24 hours for mold to develop on drywall and wood, so it’s important to address water seepage quickly.

Another cause can be poor insulation, as hot or cold air from outside meets the cold or hot air from the inside, causing condensation. Improper airflow in the basement can also contribute to mold and water damage. If you start to smell mold in your basement, it’s important to address the issue as soon as possible.

Waterproofing a basement from the inside is considered to be the better option. While the outside of the foundation may be waterproofed during the construction process, the soil can clog the waterproofing membrane, putting pressure against the wall and causing water to sit against the foundation and infiltrate the property.

By waterproofing the basement from the inside, we can catch water before it enters the property. We do this by installing a waterproofing system under the basement floor, which protects against water that is not visible.

The cost of waterproofing a basement can vary based on the size of the space, with smaller basements starting at $6,000 for 60 linear feet, medium-sized basements starting at $12,000 for 100 linear feet, and larger basements starting at $18,000 for 150 linear feet and up.
