Why Water Intrusion Happens in Los Angeles Homes

 Heavy rain, hillside runoff, hydrostatic pressure and poor drainage conditions can cause serious water intrusion issues in basements, crawlspaces, garages and below-grade structures throughout Los Angeles. Our team specializes in identifying the source of groundwater intrusion and installing waterproofing and drainage systems designed to help protect foundations and structures from future moisture damage.

Get in Touch

Why Water Intrusion Happens

Hydrostatic Pressure

 Groundwater pressure can build against below-grade walls and foundations, leading to cracks, seepage and moisture intrusion.

Hillside Drainage

 Slope runoff and saturated soil conditions can overwhelm older drainage systems and increase water intrusion risks.

Failed Waterproofing

 Older waterproofing systems can deteriorate over time, allowing groundwater to penetrate foundations and retaining walls.

Subsurface Drainage

 Proper subsurface drainage systems help collect and divert groundwater away from structures during heavy rain conditions.

Foundation, Drainage & Waterproofing Specialists

Studio City Crawlspace Water Intrusion & Foundation Drainage Repair

This Studio City home experienced severe crawlspace water intrusion during heavy rain. After excavation, we discovered missing foundation footing sections that allowed groundwater to move directly toward the structure. Our team installed new structural footings, foundation waterproofing, subsurface drainage, and a sump pump basin to collect and discharge groundwater away from the property.

Eagle Rock ADU Waterproofing, Drainage & Concrete Walkway Project

 This Eagle Rock ADU was experiencing water intrusion during rain due to poor drainage around the structure. Our team excavated and waterproofed the foundation footing area, installed a subsurface drainage system, added surface drainage, and completed a properly graded concrete walkway to help redirect water away from the ADU and protect the structure long-term.

Calabasas Crawlspace Flood Prevention & Groundwater Drainage System

This Calabasas property experienced severe yard and crawlspace flooding caused by hillside runoff and underground groundwater movement. Our team designed and installed a substantial drainage system with groundwater collection, subsurface drainage, and a sump pump basin to safely discharge water away from the property and help mitigate future flooding and moisture intrusion.
