What Is Exterior Waterproofing?
Exterior waterproofing involves excavating the soil around your foundation down to the footing level, then applying heavy-duty waterproof membranes, coatings, and drainage systems directly to the outside of your foundation walls. This approach addresses the root cause of water intrusion rather than managing the symptoms — making it the most comprehensive and permanent waterproofing solution available.
It is particularly recommended for properties with persistent water problems, significant foundation cracks, or buildings where interior solutions alone are not sufficient.
