North Beach, MD

Pump Station

Situation:

Sprayroq Certified Partner (SCP) Abel Recon undertook the rehabilitation of a pump station in North Beach, Maryland, which had suffered damage from H2S exposure, resulting in exposed aggregate and deteriorating concrete. The structure’s integrity was compromised, threatening its operational capacity and necessitating urgent intervention.

Solution:

To restore the pump station to full functionality while avoiding digging up the surrounding wetlands, Abel Recon implemented a trenchless rehabilitation approach. The team addressed low spots, spalls, and delaminations within the structure by filling them in and applying small amounts of concrete. The structural rehabilitation was completed using a 300-mil application of SprayWall. This method not only ensured comprehensive repair but also avoided the need for disruptive excavation, particularly crucial due to the presence of low-lying areas surrounding the structure.

Results:

The decision to utilize SprayWall for this job proved highly beneficial. Not only did it offer significant cost savings, with the lining process being approximately one-third of the cost of traditional excavation and replacement methods, but it also drastically reduced the timeline for completion. What potentially would have taken weeks of excavation and installation was achieved in just two days, minimizing disruption to the surrounding area and the community.

Additionally, SprayWall, with its 50-year design life, provides a long-term solution, offering peace of mind to asset owners and municipalities. With this extended lifespan, the pump station is now poised to operate efficiently for decades to come, alleviating concerns about future maintenance and ensuring continuous functionality.

Abel Recon’s utilization of SprayWall for the rehabilitation of the pump station not only restored the structure’s integrity, but also delivered significant cost savings, expedited completion, and provided long-term reliability, exemplifying the many benefits of Sprayroq’s solutions in addressing critical infrastructure challenges.
