Project Summary

The Ammons Upper Lake Dam project was an emergency spillway modification that was completed by Aggregate Group in collaboration with Main Stream Earthwork, Inc. The project sits on a picturesque lake in the Greystone community of Raleigh, NC.

In partnership with Jarco Supply, Southern Concrete Pumping and Carolina Sunrock, Aggregate Group installed all the under-slab drainage system and steel reinforcement and then placed a large spread footing and cast-in-place concrete walls. The walls were formed using Aggregate Group's own Peri Duo forming system and delivered both a durable and architecturally pleasing dam that will provide the community with safe and reliable water management for years to come.

As with any project, Aggregate Group is committed to using best-in-class workmanship to deliver both small- and large-scale commercial concrete projects with precision and efficiency.
