Residential · St. Augustine, FL
A garage slab has to take hot tires, jacks, tool drops, and moisture without curling or dusting. St. Augustine Concreters has served St. Augustine since 2016, installing and replacing garage floor concrete for homes, shops, and small warehouses with clean edges, proper joints, and drainage-aware grades.
A durable garage floor starts below the concrete. We remove failed slab sections and soft subgrade, then build a compacted base with road base or #57 stone to reduce settlement and pumping. For most garages we install a 6 mil polyethylene vapor barrier (taped seams) and reinforce with #3 or #4 rebar on chairs or 6x6 W1.4 welded wire mesh, depending on loading and crack-control needs. Forms are set square to the door opening and wall lines, and we verify elevations so the slab thickness and slope are consistent before the truck arrives.
Coastal Florida moisture and salt air make finishing and curing choices matter. We place a 4 inch slab for typical residential use and recommend 5-6 inches where heavier vehicles, lifts, or storage racks are planned, with thickened edges where specified. Control joints are cut early with a wet saw or cut with a soff-cut system to limit random cracking, then sealed as needed. Finish options include hard-trowel for a smooth surface, broom-finish for traction, or a light steel-trowel with a non-slip additive at the apron, and we use curing compound or wet curing to meet ACI-style best practices for strength and reduced dusting.
St. Augustine customers choose us because we build garage floor concrete like a working slab, not just a flat pad. You get a written scope with thickness, reinforcement, joint layout, and finish spelled out, plus straightforward scheduling and jobsite protection for doors, walls, and landscaping. Our crews use proper equipment, including skid steers for demolition and base work, plate compactors, laser levels, concrete vibrators, and professional saw-cutting, so the slab is placed to grade and finished evenly. We are licensed and insured, and we keep the site clean from demo haul-off through final washdown.
Before we pour, we walk the garage with you to confirm door clearances, slope to the overhead door, and any requirements for drains, stem walls, or existing footing tie-ins. After finishing, we review curing time, joint care, and realistic expectations (concrete can crack, joints control where it cracks) and we provide a simple care sheet for cleaning and sealing. You receive a free written estimate up front, clear line items for demo, base, reinforcement, and pour, and a finished slab ready for coatings, mats, or parking after the proper cure window. If you plan epoxy or polyaspartic later, we can coordinate surface prep details now so the floor is built to accept it.

Yes. We provide a free written estimate that outlines demolition (if needed), base prep, reinforcement, concrete thickness, finish, joints, and timeline.
Yes. We handle saw-cutting and demolition, haul-off, re-grading, compacted base installation, and a new pour with proper jointing and drainage.
When permits or inspections apply, we help coordinate the process and build to applicable Florida Building Code requirements for the scope of work.
Yes. We set forms to match door thresholds and tie into existing concrete where appropriate, using proper joints and dowels when needed to manage movement.
Avoid heavy loads too soon, keep the surface clean, and follow our curing guidance for the first 7-28 days. If sealed, use mild cleaners and avoid harsh chemicals that can degrade the sealer.
If your garage floor is cracked, heaving, holding water, or constantly producing concrete dust, a new garage floor concrete slab is often the most cost-effective reset. St. Augustine Concreters installs replacement slabs and new pours that start with proper subgrade work, a compacted base, and a joint plan that controls cracking. We build for real use, including daily vehicles, tool chests, motorcycles, and the point loads from jacks and jack stands.
A garage slab fails most often from what is underneath it or from uncontrolled shrinkage cracking. That is why we focus on removal of weak material, adding a stable aggregate base, and compacting in lifts with a plate compactor. Where moisture is a concern, we install a polyethylene vapor barrier to help keep the slab drier and reduce efflorescence and peeling issues with future coatings. Reinforcement is placed correctly so it actually works, and edges, turn-downs, and thickness are built to match the use of the space.
Finishing and curing are just as important as the pour. We can provide a smooth steel-trowel finish for easy sweeping, or a light broom texture where traction matters at the door and apron. Control joints are laid out to break the slab into panels and then cut promptly to reduce random cracking. After placement, we protect the slab with curing compound or wet curing methods to support strength gain and minimize surface dusting. If you want to coat the floor later, we will discuss finish selection and curing time so the slab is ready for proper prep and adhesion.
