  1. Inspection: Our team of experts will inspect the foundation of your home to identify any cracks, holes or other areas where water may be able to penetrate.

  2. Exterior Basement Waterproofing steps starts with excavation; our team will carefully excavate around the foundation of your home to reveal the outside surface of the foundation walls. This step is essential to properly apply the waterproof membrane and to identify any potential problem areas that may require additional attention.
