In Whitsett, North Carolina, the Lochmere Homeowners Association encountered a critical challenge with their 4-acre pond, which was failing to retain water due to a compromised concrete spillway. Recognizing the need for expert intervention, they turned to Triangle Concrete Solutions, a company known for its innovative and effective solutions in construction and repair.

The issue at hand was severe: water was seeping underneath the spillway, saturating the soil beneath and continuously filling a nearby creek, which should have remained dry except during heavy rains. Triangle Concrete Solutions quickly devised a two-phased strategy to address the problem decisively.

In the first phase, Triangle Concrete Solutions applied NCFI Terra-Lok 24-120, a single-component polyurethane, to create a grout curtain wall under the spillway. This innovative spillway polyurethane repair approach transformed the problematic soil into a solid, impervious barrier, effectively stopping water from escaping. Within hours of application, the creek’s flow reduced from a steady stream to a mere trickle, a clear indicator of the immediate success of the intervention.

Building on this success, the second phase focused on reinforcing the structural integrity of the spillway itself. The team used NCFI Strata-Fill™ 24-039 polyurethane, injected beneath the spillway slabs to fill the voids caused by erosion and reconnect the soil layers. This spillway polyurethane repair method not only stabilized the spillway but also prevented future water infiltration by sealing the joints.

The entire project was executed swiftly over three days, causing minimal disruption to the community. The effectiveness of the solutions provided by Triangle Concrete Solutions was evident as, for the first time in seven years, water flowed correctly over the spillway, filling the pond as originally designed.

The intervention by Triangle Concrete Solutions saved the Lochmere community over $160,000, money that would have otherwise been spent on a complete replacement of the spillway. More importantly, it restored the pond’s functionality and ensured the longevity of the spillway. This spillway polyurethane repair project stands as a testament to Triangle Concrete Solutions’ expertise in delivering efficient and innovative solutions that directly address the complex needs of their clients.

Through strategic planning, advanced technology, and a clear focus on sustainable outcomes, Triangle Concrete Solutions not only resolved a significant infrastructure problem but also reinforced their reputation as leaders in the construction industry. Their ability to quickly assess, plan, and remedy such a complex issue underscores their central role as a reliable and innovative contractor.
