Real Drainage, Waterproofing & Foundation Repair Projects Throughout Southern California

 Explore real-world drainage, waterproofing, sump pump, crawlspace, retaining wall, and foundation repair projects completed throughout Los Angeles and surrounding Southern California communities. Our projects highlight complex water intrusion correction, hydrostatic pressure mitigation, groundwater management, and long-term structural protection solutions for hillside and below-grade properties.

Featured Water Intrusion Projects

ADU Waterproofing & Drainage Project – Brentwood

Brentwood ADU Waterproofing & Subsurface Drainage Project

Beverly Hills Basement Waterproofing & Hydrostatic Pressure Drainage System

Beverly Hills Basement Waterproofing & Hydrostatic Pressure Drainage System

 The ADU planter at this Brentwood property was allowing water intrusion into the unit during heavy rain conditions. Our team waterproofed the exterior foundation wall, sealed vulnerable areas and installed a subsurface drainage system designed to collect and divert water away from the structure to a safe discharge location. The project was completed to help reduce hydrostatic pressure and protect the ADU from future moisture and water intrusion issues.

 Our client contacted us regarding ongoing basement moisture, mold and fungal growth at this Beverly Hills property. After inspection, we discovered the front perimeter lacked proper waterproofing and drainage. Our team installed advanced waterproofing materials, a substantial drainage system and a sump pump pit to help mitigate hydrostatic pressure and future moisture intrusion.

Pasadena Interior Basement Drainage & Negative-Side Waterproofing Project

Los Angeles Hillside Foundation Waterproofing & Groundwater Drainage Project

Los Angeles Hillside Foundation Waterproofing & Groundwater Drainage Project

 This Pasadena basement experienced repeated flooding during heavy rain due to ongoing groundwater intrusion. Since exterior excavation was not feasible, our team installed a substantial interior drainage system, a sump pump pit and negative-side waterproofing to help redirect water away from the basement and mitigate future moisture intrusion issues.
