Exterior basement waterproofing stands as a frontline defense against the forces of nature, aimed at preventing water from ever reaching the interior spaces of a home. It involves the excavation around the property to the foundation’s footing, allowing for the application of waterproof coatings and membranes directly to the exterior walls.

This method addresses root causes by managing water away from the foundation through well-designed drainage systems and landscape modifications. Key strategies include the installation of French drains, sump pumps, and specialized waterproof coatings that form an impenetrable barrier against moisture:

  • Excavation to foundation level to expose basement walls
  • Application of waterproof coatings and membranes to exterior walls
  • Installation of drainage systems like French drains and sump pumps
  • Landscape modifications to direct water away from the foundation


Interior basement waterproofing tackles moisture issues from inside the home, acting as a secondary but equally vital line of defense. WG Basement Waterproofing in Washington DC specializes in this approach, using sealants, epoxy coatings, and efficient sump pump systems to manage and expel accumulated water, effectively keeping the basement environment dry and preventing water damage.

The process includes the strategic application of waterproofing sealants and the adept installation of sump pumps and vapor barriers, aimed at controlling indoor humidity levels and preventing the seepage of external moisture through cracks and joints in the basement structure. This tailored approach ensures the longevity of the foundation and enhances the indoor air quality, safeguarding the health of the inhabitants and the structure of the space.

Frequently Asked Questions

Common causes of basement water damage stem primarily from flawed drainage systems and cracks in foundation walls. Factors like heavy rainfall, poor landscape grading, and faulty plumbing can also significantly contribute to the problem.

Basement waterproofing creates an impenetrable barrier against moisture, drastically reducing the dampness that mold and mildew thrive on. By keeping the basement dry, it denies these harmful fungi the environment they need to grow. 

The typical cost of basement waterproofing solutions varies greatly, largely depending on the extent of the waterproofing needs, type of solution implemented, and property specifics. Costs can range anywhere from a few hundred dollars for minor fixes to upwards of $10,000 or more for comprehensive systems involving exterior waterproofing and structural repairs.

A sump pump plays a pivotal role in keeping a basement dry by actively removing accumulated water from the basement’s lowest point and expelling it away from the home’s foundation. This mechanism not only prevents flooding but also reduces humidity levels, which can lead to mold and mildew growth.

Exterior basement waterproofing methods offer significant benefits by preventing water from entering the basement, thereby reducing the risk of mold and mildew growth. These methods tackle water issues at the source, ensuring a dry and healthy living space while also potentially increasing the property’s value.
