BELOW GRADE WATERPROOFING
Water intrusion below ground level can lead to leaks, efflorescence, deterioration, mold, and damage to concrete foundations and retaining walls. Architectural Restoration & Waterproofing provides below grade waterproofing services throughout San Francisco, Marin, and the greater Bay Area, with systems designed to stop water intrusion and manage groundwater around residential and commercial structures.
BELOW GRADE WATERPROOFING
Water intrusion below ground level can lead to leaks, efflorescence, deterioration, mold, and damage to concrete foundations and retaining walls. Architectural Restoration & Waterproofing provides below grade waterproofing services throughout San Francisco, Marin, and the greater Bay Area, with systems designed to stop water intrusion and manage groundwater around residential and commercial structures.
Our below grade waterproofing solutions include cementitious waterproofing systems, rubber membrane systems, sump pumps, and French drains. The appropriate system depends on the source of the water intrusion, accessibility of the exterior foundation, existing construction, and drainage conditions around the building.
Cementitious Waterproofing & Sump Systems
When the exterior side of a leaking below grade wall cannot be accessed, a cementitious waterproofing system can provide an effective solution from the interior side of the structure.
Crystalline cementitious products penetrate the capillary voids within concrete and help create a waterproof barrier against moisture intrusion. Existing coatings and deteriorated material are removed, cracks and joints are repaired as necessary, and waterproofing compounds such as Xypex and Thoroseal can be applied to properly prepared concrete surfaces.
Where groundwater cannot be removed through gravity drainage, sump pump systems can also be installed to collect and redirect water away from the structure.

Rubber Waterproofing Systems
Liquid-applied rubber waterproofing systems provide a durable, flexible barrier against water penetration and can be used on foundations, basements, sidewalks, and other areas exposed to moisture.
Products such as CIM waterproofing membranes cure to form a tough elastomeric coating that adheres to a variety of substrates while providing resistance to water, abrasion, and environmental exposure.
These systems can be particularly useful where a continuous waterproof membrane is needed around below grade concrete and other building components.

French Drain Systems
A French drain helps control groundwater before it can accumulate against a building foundation.
French drains typically use perforated drainage pipe installed within a gravel-filled trench alongside or near the foundation. Water entering the system is collected and redirected away from the building through gravity drainage or to a sump pump when gravity drainage is not possible.
Proper drainage can reduce hydrostatic pressure against below grade walls and form an important part of a comprehensive foundation and basement waterproofing system.
