Generator Building Slab Lift Project Challenges
Client: California Water Services
Location: Bakersfield, CA
Project Summary: Pump Station Generator building had severe settlement due to a severed water line undermining the support soils.
A pump station building holding backup generators was experiencing severe settlement after an 8-inch water line severed and undermined the support soil. Publicly bid project that was initially designed to use helical piers, as bedrock was at -70′ and the piles would be able to support the structure at -40′.
Generator Building Slab Lift Solutions and Results
Based on the engineering report, EagleLIFT determined that up to -20′ consisted of weak soils and could be strengthened using a two-part chemical grout and a specialized injection method, referred to as Deep Injection. EagleLIFT provided an alternate bid and subsequently won the project. After a 4 day installation, EagleLIFT stabilized and lifted the slab to grade and repaired the cracks using carbon fiber staples and epoxy.
