Sprayroq Structural Rehabilitation Case Studies

A federal facility built during WWII for the manufacturing of military grade explosives and converted into a Veterans Association Hospital Campus after the war. A freshwater treatment facility was built on the campus in the early 1950’s to provide potable water for the entire self-sufficient campus.

Rehabilitation of eighteen manholes. Approximately 200 vertical feet and two large vault structures approx. 10,000 sq./ft.

The job also dealt with below freezing temperatures and extremely narrow one-way roads for access.

Located 130 miles west of Bismarck along I-94,Medora is a famous little Badlands town with a significant tourism population. Medora offers convenient access as the gateway to the south unit of to the Teddy Roosevelt National Park, serving as a basecamp to the park with multiple history, education, and entertainment venues to enhance the tourism experience and become a destination location. Medora also serves as a famous stopping point for tourists on their way to Yellowstone National Park. Medora is one of the most popular tourist attractions in the state of North Dakota.

Reinforcement of PVC piping for freshwater skimming system. The current stainless-steel piping is expensive, and the industry was moving away from metallic components. This skimmer pipe is designed with slots to remove debris floating on the top of the water. Since the pipe is floating on the surface and is, mostly empty, the upward force is about 400 pounds. This caused a 10-inch PVC pipe to deflect and not skim equally across its length.

Bulging and sagging of the culvert’s panels were noted in 2006 and recommended for remedial action in May 2013. Maximum deflection within areas of deformation was roughly estimated to be six inches located in the upper plates of the pipe. The purpose of the rehabilitation effort is to improve the structural capacity of the pipe to reduce the chance of a culvert failure that would impact the I-90 roadway.

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 only problem was that the work needed to be done over the Christmas holiday shutdown, and neither of the structures to be rehabilitated could be taken out of service for pre-bid inspections.

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.
