JPM Construction Services pours residential and light commercial garage slabs across Marietta, GA and the surrounding Cobb County area. Whether you’re building a new attached garage, adding a detached workshop, replacing a failing slab, or pouring a foundation for an RV or storage building — every slab is built with proper base prep, reinforcement, and finish work to handle vehicle weight and Georgia weather long-term.
We handle the whole job in-house. No subcontractors juggling schedules, no quality drift between phases, and no surprise costs mid-project. From the first measurement to the final broom finish, the same crew is on site.
Every JPM garage slab project includes:
Site review and layout planning: measurements, slope evaluation, and drainage planning before any work starts
Excavation and ground prep: clearing, grading, and excavation to proper depth (typically 6-8 inches for residential garage slabs)
Vapor barrier installation: polyethylene barrier under the slab to block ground moisture from migrating up through the concrete
Compacted base: crushed stone or gravel base, mechanically compacted for stability and drainage
Forms set to spec: square, level, and properly sloped toward the garage opening for drainage
Steel reinforcement: rebar or wire mesh based on intended use (standard residential or heavy-use workshop)
Concrete pour and finish: typically 4 inches for residential garages, 6 inches for heavy-use, workshops, or RV/equipment storage
Control joints and clean edges: properly cut joints to guide cracking and finished edges for a professional look
Site cleanup: every project ends with a thorough cleanup and walkthrough
New Attached Garage Slabs
Building a new garage onto an existing home? We pour the slab to integrate with your home’s foundation, properly sloped for drainage and built to support the structure above.
Detached Garage and Workshop Slabs
Standalone garages, workshops, and outbuildings — typically poured 6 inches thick with extra reinforcement to handle equipment, storage, and project loads.
Garage Slab Replacement
Cracked, settled, or failing garage slabs removed and replaced with a properly built new slab. Includes full demolition and debris removal.
RV, Boat, and Equipment Storage Slabs
Heavy-duty slabs designed around the specific weight and footprint of what’s being stored — typically 6-8 inches thick with reinforced load points.
Garage Additions and Extensions
Adding onto an existing garage requires careful tie-in to avoid future cracking at the joint. We match elevation, reinforce the connection, and pour a clean transition.
Most residential garage slab projects in Marietta complete in 3-7 days from start to finish. Here’s what to expect:
Day 1: Site prep, excavation, and base material installation
Day 2: Forms set, vapor barrier laid, reinforcement placed
Day 3: Concrete pour and finishing (typically completes in one day)
Days 4-7: Cure time before light foot traffic; full vehicle weight at 7 days, full strength at 28 days
Demolition of an existing slab adds 1-2 days to the front of the project.

The standard residential garage slab is 4 inches thick — sufficient for passenger vehicles and typical use. For workshops, detached garages, RV storage, or heavy equipment, 6 inches is recommended. We’ll evaluate your project and recommend the right thickness during the estimate.
Most garage slabs can handle light foot traffic within 24-48 hours and standard vehicle weight at 7 days. Full strength is reached at 28 days, which is when the slab can handle heavy equipment, RVs, or workshop loads without risk.
Yes. Full demolition, debris removal, base prep, and new slab installation are handled as part of the same project — typically more cost-effective than trying to repair structural damage.
