Basement waterproofing is the process by which the experts at Strong Basements protect basements and home foundations from water damage. Utilizing a variety of techniques and materials to ensure a fully waterproofed basement, our experts rely on the application of sealants, and the installation of drains and pumps to effectively remove and direct water away from your home. 

Purpose of Basement Waterproofing

Basement waterproofing is one of the most important elements of home protection and is often considered a requirement for any buildings that rest directly against or below ground level. In regions where there is a high water content within the soil, or where the soil has the potential to rise, as a result of rain and snow, waterproofing is of the utmost importance. High water content in the soil surrounding a building’s foundation applies constant and forceful pressure against foundational walls. This pressure is referred to as hydrostatic pressure, and can force water through unprotected cracks and openings. Overtime, hydrostatic pressure has the potential to seriously damage the structural integrity of basements and foundations while contributing to the development of mold and moisture-related problems.

 Interior Basement Waterproofing

 Interior waterproofing can be an effective solution to problems associated with minor water damage such as dampness and condensation. In such instances, coatings of sealants may be used to cover and protect the source of the moisture. Unfortunately not all water damage is such an easy fix. Other options for interior waterproofing include the installation of drain and pump systems such as sump pumps, which work to drain and expel water away from the building’s interior.

Exterior Basement Waterproofing

In contrast to internal waterproofing, which aims to solve issues related to minor water damage; exterior waterproofing works to prevent water from entering the foundation of a building. Exterior waterproofing is currently the only means of preventing structural water damage that is recognized by the International Building Code (IBC). While exterior basement waterproofing can often prove to be a time-consuming and costly venture, it is undisputedly the best option when seeking to protect your home’s basement from wet conditions. Exterior waterproofing requires the excavation of soil surrounding a structure’s foundational walls in order to install a drainage system.


Water damage tends to occur over long periods of time, and can thus go undetected for several years without notice. Often caused by a variety of factors such as seepage and leaks, long-term water damage may be further exacerbated as a result of:

  • • Poor construction
    i.e. Concrete that has not cured properly, leaving it susceptible to cracks.
  • • Soil erosion and subsidence
    i.e. Soil erosion and subsidence may alter and weaken foundational structures.
  • • Broken or compromised drains and downspouts
    i.e. Most waterproofing systems rely on drains to transport water away from the foundation. When such systems become damaged or clogged, the build-up of excess water increases hydrostatic pressure on the foundation thus aggravating any existing complications.

Signs of Water Damage:

Signs of water damage may not be immediately apparent and require a keen eye to catch early on. If you suspect your home may have water damage, look for cracks in the foundation, bowed or buckling walls which may be struggling under hydrostatic pressure, efflorescence, a white, powder-like substance often found on foundational walls, and mold.
