Flatwork & Driveways in Austin
Driveways, sidewalks, patios, approaches and interior floors, finished flat and finished clean.
About flatwork and driveways
A driveway carries vehicle loads over ground that moves with moisture. Thickness and reinforcement handle the load; a properly compacted sub-base handles the movement. Skipping the base is the single most common reason a driveway looks fine for two years and then cracks along its length.
Drainage is designed, not hoped for. Flatwork needs a fall away from buildings, and the finished level has to tie into what is already there — thresholds, existing paths, kerbs and gullies. Getting that wrong is much harder to correct than getting the finish wrong.
The surface finish is a decision about grip, appearance and maintenance. Broom finishes give texture on slopes; smooth trowel suits interiors; salt, exposed aggregate and stamped finishes trade some maintenance for appearance. Colour and stamp matching on a partial replacement is genuinely difficult, because existing concrete has weathered.
Joints again decide where cracks go. On a driveway, control joints are usually cut in panels that keep each section roughly square, with isolation joints where the slab meets a garage, a path or a kerb.
What flatwork and driveways work involves
Where there is existing concrete, it is saw-cut, broken out and taken away before anything else happens.
Ground cut to depth, base course laid and compacted, levels checked against the falls.
Edges set to the finished level, mesh or bar placed on chairs.
Concrete placed, screeded to the falls and floated.
The specified surface applied in the right window — too early or too late both show.
Control joints cut, edges tooled, surface protected while it gains strength.
Materials, finishes and specifications
General trade practice for flatwork and driveways. The figures on your job are whatever ends up on your written scope.
- Driveway thickness
- Commonly 4″ for cars, 5–6″ where heavier vehicles are expected
- Concrete strength
- Typically 3,000–4,000 psi for exterior flatwork
- Reinforcement
- Welded wire mesh or #3–#4 bar, placed on chairs rather than pulled up during the pour
- Sub-base
- Compacted aggregate base, thickness set by the ground conditions
- Falls
- A consistent slope away from buildings, tied into existing levels
- Finishes
- Broom, smooth trowel, salt, exposed aggregate, stamped or stained
- Joints
- Control joints cut into roughly square panels, with isolation joints at buildings and kerbs

What decides the price of flatwork and driveways
No two jobs price the same. These are the things that move the number, and they should each appear as a line on a written quote.
- Area and thickness of the pour
- Concrete strength and mix design
- Reinforcement: mesh, rebar size and spacing
- Sub-base preparation and vapour barrier
- Surface finish and any decorative treatment
- Site access, and whether a pump is needed
- Demolition, excavation and haul-off included in the scope
- Joint layout, sealing and cure protection
What to ask before you hire
- Ask for the contractor's licence number and current insurance certificates, and check them yourself.
- Insist on an itemised quote rather than a single lump sum — thickness, reinforcement, prep, finish and haul-off should each have a line.
- Ask whether the crew on site works for the company or is brokered out, and who your point of contact is on pour day.
- Ask what the sub-base preparation is, what reinforcement is specified, and how joints will be laid out. Vague answers are the warning sign.
- Ask what happens if the work fails later, and whether that answer is written into the contract rather than said on the doorstep.
- Ask for recent references for the same kind of work in your area, and call one.
What goes wrong on these jobs
- Cracking along the length of a driveway from an unprepared sub-base.
- Water sitting on a patio or running back towards a building.
- Surface scaling where the finish was closed too early.
- New concrete that does not match the colour or stamp of the old.
- Trip hazards where a new slab meets an existing path at the wrong level.
Straight answers
Around 4″ for cars is common, more where heavier vehicles are expected — but thickness only works over a properly compacted base.
Approximately. Existing concrete has weathered, so a match is closest when a whole panel is replaced rather than a patch.
Concrete keeps gaining strength for weeks. The contractor pouring it should tell you the figures for the mix they used.
