Exterior waterproofing involves the application of a waterproof membrane, such as Blueskin or dimple membrane, and techniques to prevent water infiltration and damage to the foundation from the outside. This method focuses on addressing the root cause of water intrusion by creating a barrier between the exterior soil and the foundation walls. Typically, the process begins with excavation around the perimeter of the foundation to expose the exterior walls completely. Any existing cracks or deteriorated areas are repaired, and the surface is thoroughly cleaned and prepared. Waterproofing membrane is then applied to the exterior walls to create a watertight seal. Additionally, drainage systems, such as weeping tile and sump pump, may be installed to redirect water away from the foundation. By preventing water from reaching the foundation walls, exterior waterproofing helps to maintain the structural integrity of the basement and protect against moisture-related issues such as mold, mildew, musty smells, and foundation damage.
