About Us


Welcome to Petra Foundation Repair of Costa Mesa, CA. We are your local experts specializing in comprehensive structural stabilization for homeowners throughout Costa Mesa and Orange County. We deeply understand how the unique coastal climate and varying terrain ranging from the sandy bluffs near the Santa Ana River to the expansive inland clay soils make properties highly susceptible to differential settlement. Fluctuating moisture levels can exert massive hydrostatic pressure, leading to foundation settlement, bowing walls, and structural cracking. We are here to ensure that cosmetic hairline shrinkage cracks never turn into massive structural failures.

Our Mission & Commitment

Our mission is to provide accurate diagnosis, precise engineered specifications, and guaranteed long term foundation health for every property we service. We are fully committed to quality and safety, ensuring that our engineering backed methods meet strict California Building Code standards. Whether you are dealing with a failing slab on grade foundation or require raised foundation support, our focus is on delivering permanent stability and peace of mind through expert workmanship and dependable service.

We provide advanced, permanent solutions for active foundation movement and structural damage. Our specialized services include:

  • Advanced Underpinning: We deploy galvanized helical piers and push piers that are driven deep into load bearing strata to permanently stabilize settling foundations.


  • Structural Crack Mitigation: For structural cracks wider than 1/8 inch with vertical displacement, our expert technicians utilize high pressure epoxy injection to restore load transfer and polyurethane foam injection to stop active water intrusion through stem walls.


  • Seismic Retrofitting: To combat Southern Californias inherent earthquake risks, we provide crucial seismic retrofitting services designed to securely fasten your home to its foundation.
