A family crew that pours like it's their own yard.
GM Outline Construction is a family-owned concrete, hardscape, and grading contractor based in Acworth, Georgia. We work on residential and commercial properties across North Atlanta — and every job is run by the same crew that's been pouring together for years.
Built on word of mouth.
GM Outline was started by a small group of finishers who got tired of seeing big-name companies sub the work out to crews they'd never trained. We do it the old way — the owner is on every job, the crew that quotes the work is the crew that pours it, and nothing leaves the site until it's right.
We pour driveways and patios for homeowners. We build retaining walls and stepping-stone paths for landscapers. We pour loading docks, ADA ramps, and sidewalks for property managers and shop owners. And we grade and drain the dirt before any of it gets touched.
Every job we've ever finished has earned a 5-star review. That's not luck — that's the standard we hold the work to.

Three rules. No exceptions.
Show up.
We arrive when we say. We start when we say. We finish when we say. Construction shouldn't be a mystery.
Build it right.
Proper base, proper reinforcement, proper joints, proper sealer. We pour to spec — not to the lowest bid.
Stand behind it.
If something goes wrong, we come back. Every job carries a written warranty and a phone number that actually answers.
North Atlanta. Built local.
