Sprayroq Structural Rehabilitation Case Studies

The city of Carmel, Indiana was in a dire situation when a rusted water pipe ruptured creating a massive sinkhole in the road at a major intersection. Fortunately, officers arrived at the scene and were able to secure the area surrounding the 12 by 18 feet hole before any accidents occurred.  The storm pipe was removed and replaced but the city was faced with another obstacle. There was another 220 linear feet of storm pipe from the replaced section to a drainage lake that could collapse at any time!

At a Sprayroq product installation demonstration in Lancaster, S.C., Public Works Director Mack McDonald observed the use of SprayWall polyurethane, which he believed could help restore an aging clarifier at the city's wastewater treatment plant. The structure was not only crumbling away daily, but due to an uneven substrate, was very difficult to clean and keep free of algae.

Roughly 15,000 lbs. of material was used for all four pipes. Because of the remarkably quick cure time, water flow could be restored within minutes of finishing the coating application and thickness testing.

Lake Heron’s water level was so low that it was impossible for the city of Liverpool, Pennsylvania, to allow any recreational use. Upon further review, the repair crew realized that the lake’s overflow pipe located on the edge of the lake had deteriorated to the point where many flow points were located along its length.

The Michelin Plant in Greenville, South Carolina, had a substantial infrastructure issue that required rehabilitation.

The Kelly Station, a 40+ year old brick construction lift station operated by the City of Seneca, South Carolina had significant evidence of infiltration, root intrusion and a high level of debris build-up on its walls. It was determined that a replacement should be scheduled within a years time.

On Route 23 in Alvada, Ohio, two side-by-side 13’-6”W x 8’-6”H x 90’L corrugated steel sheet plate culverts running underneath the roadway needed corrosion protection.

A trenchless rehabilitation project on 200 feet of an arch tunnel, in old town Guangzhou in Guangdong Province of the People’s Republic of China, an ideal opportunity to demonstrate Sprayroq products for the city’s utility departments.

Master Lift Station 13A in Manatee County, FL was in need of rehabilitation due to heavy deterioration of its walls and high levels of dA sanitary manhole at the intersection of North Lake Way and Mockingbird Trail in the Town of Palm Beach, Fla., was a heavily deteriorated brick structure exhibiting the presence of groundwater infiltration.

Master Lift Station 13A in Manatee County, FL was in need of rehabilitation due to heavy deterioration of its walls and high levels of debris that was causing the overuse of pumps.

The 52-inch storm sewer was installed in the early 1900s. The line takes in all of the storm water for the south side of the city. The sewer is 20 feet deep and runs along railroad tracks, then discharges into the Manistee River.

The existing sewer to be rehabilitated was approximately 80 years old and was located 20 ft. below ground in Evanston, Illinois, a northern suburb of Chicago. The sewer started at a river edge overflow chamber in a school parking lot.

The galvanized corrugated vertical inflow stand pipe on the golf course 6 acre pond was deteriorated badly.  The holes in the pipe were significant and caused the pond level to be over 3 feet below normal pond elevation.
