The Greenfield Lake Spillway Had Significant Cracking, Here’s How It Was Fixed

Major repairs to the Greenfield Lake spillway were completed earlier this year. The spillway serves as an outfall to the lake, where water from Greenfield Lake eventually flows into the Cape Fear River.

Over the years significant cracking developed in the spillway’s concrete structure due to settling.

The $1.1 million repair project included retrofitting the spillway’s foundation with 12, massive helical piers to stabilize it and prevent future cracking. Crews also added new concrete topping slabs, replaced the timber framing on the existing guardrails on the walkway, and re-tensioned the existing cables in the guardrails.

These improvements ensure that the spillway continues to serve as a reliable outfall to the lake for years to come.
