EagleLIFT completes an incredible project in Brisbane, CA, where we lift a 45,000 sqft warehouse 15 inches from exterior to interior. The project is completed using a combination of Push Piers and Polyurethane Grout.
Caltrans had a problem with one of its Ferry loading docks in Rio Vista, CA – it was being undermined by a family of beavers that had made a home underneath the boat ramp! As strong as the ramp was built, the concrete would not be able to withstand the significant weight stess on its own, it would need adequate support soils to help support it.
The beavers had caused voids ranging from 6″ to 1′ throughout the 44’x24′ slab, and the voids needed to be filled and the weight-bearing capacity of the soil restored or there would be potential for service interruption. Caltrans contacted EagleLIFT to see if the problem could be solved.
The California Slab Lift Solution
Once the void locations were determined by use of Ground Penetrating Radar (GPR), EagleLIFT utilized the URETEK Method® to fill the voids and densify the remaining soil. The URETEK Method® is a unique application that allows for a high density structural polymer to be injected underneath a structure with only 1/2″ holes in the slab. Once injected, the polyurethane seeks out the voids in liquid form and then it begins to expand through the void and the adjacent soil, creating a subsurface weight-bearing monolith. URETEK’s 486STAR polymer was ideal for this application due to its hydro-insensitivity, quick set time and it being environmentally inert.
The loading ramp was stabilized in 3 shifts, minimizing the downtime of the dock and restoring service in one day. All of the voids were stabilized and the weight-bearing capacity of the concrete ramp was restored. All of this was done without harming one single Beaver!
Here’s a throwback for you all — this handcrafted original EagleLIFT sign (from about 6 years ago) is still up and standing in Pahrump, Nevada! We love it! Thanks for the memory, Ryan!
