The unidentified man was working in a ditch Tuesday when the wall collapsed, pinning him face down against a concrete wall, Capt. Tommy Rutledge of the Gwinnett County fire department, said.
During the hour-long rescue, the man was able to talk to fire department personnel through a two-foot hole while up to his waist in dirt and concrete, The Atlanta Journal-Constitution reported.
Firefighters were concerned about internal injuries to the victim, due to the weight of the concrete, Rutledge said.
He was transported to a hospital after he was freed, the newspaper said.
