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.

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…
Aged Infrastructure Causes Parking Lot Collapse at Mississippi IHOP
Could you imagine, for a moment, enjoying your blueberry pancakes at your local IHOP and suddenly seeing half of the cars get swallowed up by the parking lot? This is exactly what happened at a local IHOP in Meridian, Mississippi on Monday, November 9th, where 12 cars were swallowed up by a 30ft wide by 600ft long trench.
The parking lot collapse appears to have been caused by the failure of an old culvert that existed below the parking lot and located in front of the restaurant, making those upfront parking spaces not as much of a luxury as they might have appeared!
Below is a video by CNN discussing the event with Patrick Abbott, Professor of Geology at San Diego State University. Professor Abbott speculates that the failure was likely caused by an old drainage culvert or pipe that had failed due to age, loose support soils and excessive weight on top…
