Structural solutions. Dependable performance.

Medora, ND

Located 130 miles west of Bismarck along I-94, Medora is a famous little Badlands town with a significant tourism population.

Problem:

A 90” corrugated steel plate culvert (commonly referenced as CMP) that runs for 700 linear feet directly under Interstate 94 near Medora was badly decomposed.

Solution:

The solution design called for a 500-mil application, and it was decided to spray only the first 130 feet, starting from the point of entry at the inlet end.

The Sprayroq Certified Partner (SCP) successfully installed Spraywall without disruption to the Medora tourist traffic and while minimizing construction capital costs but also maximizing on Spraywall’s long term return on investment (ROI).

Wormsley, PA

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.

Big Sky, MT

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.

Carmel, IN

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.

Problem:

There was another 220 linear feet of storm pipe from the replaced section to a drainage lake that could collapse at any time!

Solution:

Conco Spray Solutions provided the city with a structural liner that would hold infiltration back and provide a long-term structural solution with a 50-year design life.

By providing a quick application and not removing the existing structure, Conco Spray Solutions minimalized the disruption of traffic flow and preserved the natural landscape in Carmel, Indiana.

Lancaster, SC Clarifier

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.
