December 26, 2022

Sharing is caring!

It can be a nightmare to discover flooding in your basement. Water and moisture can enter through various channels, including improperly sealed window sills. It can also enter the basement via cracks in the walls or floor. In addition, moisture issues can cause extensive damage to items stored in your basement and to carpet, drywall, wood, and other materials.

Waterproofing a basement refers to the methods and supplies used to stop water from entering the basement of your property. Applying sealant materials, setting up drains and sump pumps, and other tasks may be necessary to waterproof a basement below ground level.

Why are Basements Prone to Moisture and Water Damage

Basements are particularly prone to the development of moisture and dampness. Under the basement floor and walls, hydrostatic pressure is generated by water in the soil. This hydrostatic pressure has the potential to push water through fractures, leading to severe structural damage, mold growth, wood rot, and other moisture-related issues.

The major contributors are improper soil and drainage system, poorly installed and maintained gutters, unsuitable slopes, hydrostatic pressure, condensation, and other drainage systems. The purpose of installing basement waterproofing is to prevent all of these.

What Is the Best Basement Waterproofing Method?

Depending on the severity of the problem, most homeowners choose a temporary solution, but they frequently have to install a drainage system to effectively solve their basement water problem. In addition, exterior waterproofing is often far more expensive than interior waterproofing since it necessitates heavy equipment, more human resources, and takes longer to finish.

However, if cost is not a consideration, exterior waterproofing is the most effective basement waterproofing method. Professional waterproofing companies frequently utilize a variety of strategies. A multilayered approach to basement waterproofing is often the best method.

Three Basement Waterproofing Methods That Protect Your Home from Damage

There are several strategies for preventing basement flooding. However, discussed in this article are three methods of basement waterproofing;

  • Interior basement waterproofing
  • Exterior basement waterproofing
  • Drainage systems

Interior Waterproofing

The most straightforward and economical waterproofing techniques are usually those used inside. To start, ensure that any gaps or breaches in your basement walls, floors, and the areas surrounding its windows and doors are adequately sealed and watertight.

The first step in ensuring your basement stays dry is to seal the areas where water most frequently enters correctly. These cracks can be sealed on the basement with special sealants to stop additional moisture from entering. These sealants have extensive warranties that guarantee their efficacy and are pretty compelling.

Condensation is avoided by using interior waterproofing techniques like waterproof sealants, which also effectively control humidity levels. Basement walls and flooring can be coated with these coatings to create a waterproof barrier. Despite being a crucial stage in the overall waterproofing procedure, these interior sealants must deal with the underlying issues producing moisture. More significant problems are typically discovered outside.

Exterior Basement Waterproofing

Wet basements usually have an external cause. When waterproofing your basement, look beyond the walls. Exterior waterproofing is more involved than interior sealing. When waterproofing the exterior, seek an expert.

Exterior waterproofing entails excavating the home’s foundation, a labor-intensive operation requiring heavy equipment. Once all the earth surrounding the foundation has been removed, a waterproof sealer is applied to the external walls. This polymer-based sealant should last the building’s lifetime. Exterior waterproofing should happen during construction. Exterior approaches should also include gutters. Gutters direct rainwater away from your home’s foundation when appropriately installed. However, these systems can backfire if not properly installed or maintained. Clogged gutters that drain too close to your foundation deposit water along your home’s base. Keep your gutters clean to ensure good function. Ensure downspouts direct water far away from your home as possible.

Drainage Systems

Drainage issues generate most basement dampness. Proper drainage is needed to keep your basement dry. These drainage systems direct water away from your home’s foundation.

Drainage systems assist in regulating water around your home. First, inspect your home’s soil. Soils drain differently. Make sure your home is surrounded by well-draining soil.

Each home’s drainage is different, so check it thoroughly. Check your foundation’s slope. Depending on your situation, you may need a French drain or sump pump to remove the inside water. These interior drainage systems move moisture away from your basement. These systems should be power-outage-ready. Fixing a sump pump or internal drainage system can be difficult. When considering this waterproofing method, consult a professional.
