Chris-Hill has the employees and equipment to perform most any civil construction project. Here are a few of our more interesting miscellaneous projects performed over the past few years.
White River Dam #2 Repairs
Grout was pumped into bags to create grout columns to reinforce an old set of stairs on a leaky dam.
Earthen Dam Repair with Grout Injection
A grout injection method was used to fill voids in a dam surrounding a pond at Chris-Hill's main office. Water continually leaked through the dam before the voids were plugged with grout.
Cargill Roadway Grout Injection
A Beretta drill rig was used to drill through existing pavement and fill a sinkhole with grout that had been discovered under a roadway at Cargill's Memphis plant.
Ductile Iron Pile Tension Load Test
Chris-Hill installed and performed a static tensile capacity load test to 50 kips on a production ductile iron pile for a project in Dickson, TN.
Little Rock Air Force Base Foundation Lifting
Chris-Hill lifted three façades that were settling away from a building at the Little Rock Airforce Base. Helical piers with a lifting bracket connected to the footings and hydraulic jacks were used to raise the building entrances.
Poplar Avenue Bridge Jacking
Chris-Hill raised an existing bridge on Poplar Ave in Memphis, TN to create more headroom under the bridge for traffic on Interstate 240.
