Underpinning is the process of strengthening and supporting a foundation. With proper design and installation, underpinning can be used to lift structures to an acceptable elevation and provides vertical support to prevent the area from experiencing additional settling.
Before you trust your commercial foundation repair needs to just anyone, see the projects below for a sample of what Power Lift can do for you.
The home offices of the Louisiana National Guard in Bossier City, Louisiana began to show signs of settlement over time. Accordingly, state officials prepared a preliminary plan of repair. Upon work start, Power Lift identified major variations between the perceived foundation construction and the actual foundation construction. Accordingly, Power Lift teamed with Smith Engineering, Inc., of Bossier City, Louisiana, to develop an appropriate repair plan.
In March of 2008, Power Lift was contacted by college personnel reporting interior distress of the interior slab and interior load bearing walls. The distress observed posed life safety issues such as doors that would not open and close properly and trip hazards in the floor slab. Power Lift’s synchronized lifting system was utilized to simultaneously raise 99 piles that had been installed to support the walls and slab.
The wood floor framing system of this historic hotel had settled more than 8.5” over the years. Power Lift worked with Key Construction and the EOR to design and install a new steel support system to carry each floor load. Power Lift’s unified lifting system was used to simultaneously raise new steel basement support columns 6.5” to remedy the existing settlement.
Interior foundation walls at this Wichita, KS elementary school had settled over 5” causing life safety concerns due to inoperable doors and excessive floor slopes. Power Lift worked with MKEC Engineering Consultants, Inc. to design an underpinning and lifting system to remedy the problem. Power Lift’s synchronized hydraulic lifting system raised the foundation more than 5”, back to near its original position where it was permanently secured.
In the summer of 2006, settlement was observed by library personnel. The settlement intensified into the fall necessitating emergency repairs to halt the ongoing settlement. Power Lift’s piles were driven more than 20’ and founded in the underlying shale stratum to permanently secure the building’s foundation.
The building’s ornate entrance began experiencing settlement shortly after construction. Poorly compacted basement backfill was allowing settlement of the shallow entrance foundations. Power Lift worked with Ross Builders, Inc., to develop an underpinning and lifting system to raise and permanently support the structure.
Shortly after removal of underground fuel storage tanks and contaminated soils, the Raytown fire station began to experience excessive foundation settlement along the north wall. Power Lift installed 36 driven steel piles and raised the structure more than 4” to correct the problem.
Power Lift was contacted by the Yantis Company regarding elevating of two newly constructed twin box culverts. It was determined an error had occurred when establishing the benchmark for the subdivision development. One culvert needed to be raised 3’ and the other 3’-6”. Power Lift teamed with the San Antonio, Texas engineering firm of Cutler Gallaway Services, Inc., to develop a unique solution to elevate and salvage these culverts utilizing Power Lift’s synchronized lifting system.
Poor surface drainage conditions and water infiltration caused excessive settlement of the exterior and interior southwest corner of this two-story office building. Power Lift worked with a local engineer to design an underpinning system to raise and re-support the distressed area of the building. Utilizing Power Lift’s unified, synchronized lifting system, the perimeter and interior foundations and slab were raised back to their original elevation and secured.
