In April 2014, Florida’s panhandle experienced a historic flooding event, which was highlighted by 20 in. of rainfall in just two days. For perspective, on average, the rainfall in this area is just more than 60 in. a year.
This once-a-century event caused numerous sinkholes, portions of Interstate-10 were closed and the soils of the entire region were completely saturated for an extended period of time. As the rain waters eventually receded, a large amount of voids were created in the soil, wreaking havoc on the affected areas public works and infrastructure systems.

Inflow and Infiltration Trenchless Repair
This new video highlights three projects where the URETEK polymer injection process is used to trenchlessly seal and repair lateral lines and manholes from inflow and infiltration (I/I). The application is quick and cost-effective and provides effective I/I mitigation.
Manhole Degradation Repair
The City of Florence, in Kentucky, recently called upon Ground Works Solutions to repair five, failing sanitary manholes in their system, mainly due to a high concentration of hydrogen sulfide, which was degrading the precast walls of the manholes. Since the City of Florence had never used this application before, they were interested in this test to see if the quality was acceptable for additional future repairs.
Ground Works Solutions sealed all leaks and installed a one-inch thick, structural, centrifugally cast, cement liner for the full depth of the five manholes. The liner also included ConShield, a concrete additive to resist hydrogen sulfide corrosion. Thiobacyllus bacteria forms on the walls of sanitary structures due to the presence of hydrogen sulfide. This bacteria produces sulfuric acid that…
Zero Excavation Inflow & Infiltration Restoration At the Naval Air Station in Pensacola after a High Water Event
Ever since the U.S. purchased Florida from Spain in 1821, the site where the Naval Air Station (NAS) in Pensacola currently stands has provided a base for military operations. In 1826, construction began on the Pensacola Navy Yard and it eventually became one of the “best-equipped naval stations” in the U.S. During this period, the Navy Yard was used for docking and repairing the warships of that period. When the Navy saw the advantages of aviation in combat, Pensacola became an aviation training station in 1914 and the station was built on the side of the old Navy Yard. In 2014, NAS Whiting Field celebrated 71 years in operation and is considered to be the “backbone of the Navy’s flight program” and is still one of the most important Navy bases in the U.S.
