Exterior Basement Waterproofing: 5 Solutions Exterior Basement Waterproofing: 5 Solutions

Interior waterproofing solves many basement-related problems, but exterior basement waterproofing provides additional options for the homeowner. Since water usually causes problems from the outside, especially in the rainy season, it is important to consider the right type of exterior waterproofing for your home. Here are several solutions that will help you fight water from entering your home.

Sealing the Foundation Walls

Waterproofing your home foundation with waterproofing material is a good way to prevent water from entering the basement. Since the waterproof coating for basement foundations fades over time, ensure that you regularly inspect the exterior walls for areas in need of replacement.

Purchase exterior wall sealant and determine which water sealer is best for the foundation material. Hire a professional to apply the coating. Apply it yourself if you want to cut costs. Sealing the walls with waterproof material will prevent water from entering the basement.

Installing Downspouts and Gutters

The roof is a very important waterproofing system as it protects both the interior and the exterior walls. Directing water away from the home is a good exterior basement waterproofing solution.

Install the downspouts and gutters correctly, leading water to an efficient external drainage system to ensure that it does not penetrate the basement. If there is a roof drainage system already installed, check for damage and blockage. Gutters become clogged with leaves, dirt, and debris. Clean the gutter regularly or install gutter covers.

Installing External Drainage Systems

Installing an exterior drainage system requires digging the soil next to the basement walls and installing of boards and drainage pipes against the wall. Doing so will direct the water coming from the surface away from the walls. Although this system is quite an expensive solution, it is recommended for exterior walls that are below ground level.

Correcting Ground Slopes

An alternative to exterior drainage systems is correcting the ground slopes that surround the walls of the basement. The ground should slope at least 10-degrees and at a distance of 5-feet from the exterior basement walls.

This angle will reduce the chance of pooling water. Such water eventually seeps into the ground and enters the basement walls; it should be avoided at all costs.

Structural Repair

Cracks and other structural damage are potential problems when it comes to exterior basement waterproofing. In order to waterproof the area, it is necessary to fix cracks and other inconsistencies in the foundation walls. Before resealing the entire foundation wall or installing exterior drainage systems, repair all cracks and damages to the basement foundation. Inject cracks with epoxy or restructures using the same foundation material as for the basement walls.
