Exterior foundation waterproofing is a repair approach that addresses water intrusion at the outside surface of the foundation.
Instead of managing water after it enters, this method focuses on stopping it at the source by sealing and protecting the exterior wall.
It is often used when conditions outside the foundation are contributing to water intrusion and interior solutions alone are not sufficient.
Exterior foundation waterproofing is used to address water intrusion problems that develop along the outside of foundation walls where groundwater and surrounding soil place moisture against the structure.
Exterior waterproofing may be used to address issues such as:
In some cases, property owners choose exterior waterproofing as a preventative measure to add protection before water intrusion issues develop.

Water buildup around foundation walls is typically caused by saturated soil and poor drainage near the structure.
When soil becomes saturated from rain, snowmelt, or groundwater, pressure builds against the foundation. This pressure, known as hydrostatic pressure, can force water through cracks, joints, and porous materials.
Common causes include:
When water remains in contact with the foundation, the risk of intrusion increases.
Exterior foundation waterproofing addresses this by sealing and protecting the foundation at the point where pressure occurs.

Each project is tailored to the specific conditions at the property. Exterior waterproofing may be completed in targeted areas or around the full perimeter, depending on what is needed to properly address the issue.
When needed, drainage components such as drain tile, cleanouts, or tied-in systems may be included as part of the repair.
The process generally involves:
Permits are obtained when required, and all work is completed in accordance with local building codes.
At Suburban Basement, we focus on addressing the source of the problem, not just the symptoms, for a long-term solution.

Exterior foundation waterproofing can be applied across a wide range of structures when conditions at the exterior foundation require direct access. Repairs may be completed in targeted areas or as a full perimeter system, depending on the structure, site conditions, and your preferences.
Best for: Basement wall leaks caused by soil moisture and groundwater pressure
Examples include:
Best for: Multi-unit and occupied structures requiring controlled excavation and targeted repairs
Examples include:
Best for: Large or complex structures with groundwater exposure
Examples include:
Exterior foundation waterproofing is a flexible repair approach that can be adapted to different building types, helping address water intrusion conditions at the exterior foundation wall regardless of the size or complexity of the structure.

Exterior waterproofing is typically recommended when water intrusion is being caused by conditions outside the foundation that cannot be reliably addressed from inside the structure alone. Exterior waterproofing is typically recommended when water intrusion is being caused by conditions outside the foundation that cannot be reliably addressed from inside the structure alone. This may include groundwater pressure, deteriorated exterior materials, or situations where addressing the problem at the source provides a more reliable long-term solution.
Yes, exterior foundation waterproofing requires excavation along the affected portion of the foundation to access the area where water intrusion is occurring. Depending on the conditions, excavation may be limited to a targeted area or extended along the full perimeter of the structure.
Yes, exterior foundation waterproofing can be performed on a specific area of the foundation when water intrusion is isolated to one location. In other cases, a larger portion or full perimeter may be recommended based on the overall conditions and how water is interacting with the structure.
When properly installed, exterior foundation waterproofing is designed to provide long-term protection against water intrusion. At Suburban Basement, this service is backed by a full warranty, providing additional confidence in the durability and performance of the repair.
The cost of exterior foundation waterproofing can vary depending on factors such as the length of the foundation being excavated, site accessibility, soil conditions, and whether structural repairs are needed. Because each situation is different, the best way to determine cost is through an assessment of the specific conditions at the property.
Exterior waterproofing involves excavation, which can temporarily impact landscaping and access around the structure. Care is taken to limit disruption where possible and restore the area after the repair is completed, while also supporting proper drainage conditions around the foundation.
Exterior waterproofing is designed to stop water intrusion at the source along the foundation. However, additional factors such as interior drainage systems, plumbing issues, or surface water conditions may also need to be addressed depending on the situation. A full evaluation helps determine the most effective approach.
Not every situation requires exterior waterproofing. In some cases, interior systems or targeted repairs may be more appropriate depending on how and where water is entering. The most effective approach is determined by evaluating the conditions at the property and identifying the source of the problem before recommending a solution. A full evaluation helps determine the most effective approach.
Hydrostatic pressure is the force created when water builds up in the soil surrounding a foundation. As pressure increases, it can push moisture through cracks or porous areas of the foundation.
A waterproofing membrane is a protective material applied to the exterior surface of a foundation to create a barrier against groundwater and moisture intrusion.
Excavation is the process of removing soil around a foundation to expose the exterior so repairs and waterproofing can be performed.
A foundation crack is an opening in the foundation that can allow water to enter the structure. Cracks may form due to settlement, pressure, or changes in soil conditions.
Soil saturation occurs when the ground around a foundation becomes fully or heavily soaked with water, increasing pressure against the structure and the likelihood of moisture intrusion.
Exterior drainage conditions refer to how water flows and collects around a structure based on grading, soil type, and drainage systems. Poor drainage can lead to water buildup along the foundation.
Targeted waterproofing refers to applying exterior waterproofing to a specific section of the foundation where a problem has been identified, rather than addressing the entire structure.
Full perimeter waterproofing involves excavating and waterproofing the entire foundation. This approach may be recommended when conditions affect multiple areas or the full structure.
Groundwater is water that exists within the soil surrounding a foundation. When it comes into contact with the structure, it can contribute to water intrusion if not properly managed.
Foundation settlement is the movement of a structure caused by changes in the soil beneath or around it. This movement can affect drainage patterns and create conditions that allow water to collect near the foundation.
The examples below show exterior foundation waterproofing in progress, including coating, crack repair, drainage installation, membrane protection, and other steps used to help stop water before it reaches the structure.
