Exterior Foundation Membranes

Does installing exterior foundation membranes during basement waterproofing require excavation around the home?

Yes, installing exterior foundation membranes during professional basement waterproofing does require excavation around the home. The membranes need to be applied directly to the outside surface of the foundation walls to create a watertight barrier.

The process starts with carefully digging a trench around the perimeter of your home, typically down to the foundation footing. This excavation allows the waterproofing team to access the foundation, clean the walls, repair cracks, and apply the exterior foundation membranes. Excavation is necessary because these membranes work by stopping water at its source—before it reaches the foundation.

While this may sound disruptive, professionals use small excavators or hand tools to minimize impact. Landscaping, patios, or other features close to the house may need to be temporarily removed and restored afterward.

Although the process requires time and effort, it’s worth it for the long-term benefits. Installing exterior membranes with proper excavation ensures your basement stays dry and your foundation remains protected from water damage for years to come.
