The condition of water and sewer collection systems can be assessed by scoping the lines and other structures. This process involves running a camera through lines and access points to identify potential issues. Once a comprehensive inspection is completed and a list of issues is compiled, the next step is remedying the problems. Traditional excavation and replacement is one option. This process involves digging trenches to expose the damaged pipeline or other buried structures so that they can be repaired or replaced. An alternative option is trenchless cured-in-place piping (CIPP) and cast-in-place repairs for vertical access points like manholes. These no-dig solutions involve accessing the damaged pipe or manhole from a single access point and installing a liner inside the existing pipe or manhole. Trenchless technologies have surged in popularity in recent years because they are less disruptive, quicker and more cost-effective.
Sprayroq®, Inc. develops specialized protective and structural lining systems for a variety of ever-increasing markets and applications worldwide. Their core product, SprayWall®, is a product we use in our infrastructure rehabilitation services. It uses the same delivery equipment, but are designed and furnished for different applications.
SprayWall® is a self-priming polyurethane lining that reinstates structural integrity, provides infiltration control and chemical resistance. It may be applied up to 500 mils (1/2”) thick in a single application. SprayWall® begins to gel in about 8 seconds, with a tack-free condition after 2 minutes. Within 60 minutes, the initial cure is complete and the structure is capable of accepting flow, while complete curing continues over the next 72 hours. SprayWall®’s quick curing time allows the newly protected structure to be returned to service shortly after the application is completed, making it ideal for use on potable water (NSF 61 approved), wastewater, and stormwater rehabilitation, when keeping flow and traffic disruption to a minimum is critical.
