Concrete looks simple and is not. Depth, base preparation, reinforcement, joint spacing and finishing all decide whether a slab lasts twenty years or cracks in its second winter. We pour to spec, not to whatever gets the truck emptied fastest.

We do residential and commercial flatwork across the Bronx, Queens, Brooklyn, Manhattan and Westchester, including sidewalk work that has to satisfy NYC DOT inspection.

What this service covers

  • Sidewalks poured to DOT specification
  • Driveways and aprons
  • Patios, walkways and slabs
  • Garage and basement floors
  • Foundation and footing work
  • Concrete steps and landings

When to call us

Signs you need concrete

If you recognise any of these, it is worth having someone look before it gets more expensive.

  • Cracks wider than a quarter inch
  • Sections that have settled or lifted
  • Surface flaking or pitting
  • Water pooling instead of draining away

What causes it

Why this happens

Almost every concrete failure we are called to traces back to what happened before the pour. Base not compacted in layers, no reinforcement, joints cut too late or not at all, or the mix watered down on site to make it easier to place. Concrete is unforgiving about all four. You cannot see any of it once the surface is finished, which is exactly why cheap concrete work looks fine for two years and then fails.

Budget guidance

What concrete costs in NYC

Residential flatwork commonly runs 12 to 22 dollars per square foot depending on thickness, reinforcement and finish. Sidewalk work built to DOT specification sits at the upper end because the spec is stricter. Demolition and removal of existing concrete is charged separately and is a real cost, not a rounding error.

These are indicative ranges to help you budget, not a quote. Every building is different and we price after seeing the job.

What we work with

Materials and systems

  • 3,500 to 4,000 psi mixes
  • Wire mesh and rebar reinforcement
  • Broom, trowel and exposed aggregate finishes
  • Compacted stone base and vapour barrier

How it works

Straightforward from the first call

Step 1

You call or send photos

Tell us the area and what the surface is doing. We come out and measure properly.

Step 2

Site check and levels

We check drainage and what is underneath, because the base decides how long it lasts.

Step 3

Written scope and price

Square footage, thickness, reinforcement and finish, all itemised.

Step 4

Excavate, base, pour, cure

Base compacted in layers, joints cut on time, and we tell you when you can use it.

Questions

Concrete questions

How thick should a residential driveway be?

Four inches over a compacted base for cars, five to six inches where trucks or heavy vehicles park. Anything less will crack under load no matter how good the finish looks.

How long before I can drive on new concrete?

Foot traffic after roughly 24 to 48 hours. Vehicles after seven days minimum. Full cure strength takes about 28 days.

Do you replace or resurface?

If the slab is structurally sound and the problem is surface only, resurfacing is cheaper and works well. If it has settled, heaved or cracked through, replacement is the only lasting fix.
