"They came out looked over the sidewalk that had sunk, pointed out some other critical areas which would prevent foundation problems,, provided an estimate. They were responsive and very professional. That week the work was completed. Their van and equipment is of high quality as is their work. They did an excellent job with clean up. I highly recommend. I was extremely pleased."

"They were efficent and completed the work in one day. They were clean and left no mess, covered the floors so they remained clean. One of the workmen fixed by door to the garage with a a specail screw so it does not stick any loner when opening and closing the door. Also told me how to tighten my screen door so it will not sag in the future. Nice bonus.

"Javier at TN Construction was amazing! As project manager (and worker) he was thorough, professional, knowledgeable, and a great guy to work with. He listened carefully to my questions and proposals for what we wanted done, then followed through precisely. He was quick to respond to texts. And, most shockingly of all in my experience with contractors, his crew was at our house, prepared, with everything they needed, exactly when he said they would be! They went the extra mile to please us and they certainly did! I feel confident that Javier and his crew would go that extra mile for all their clients."

Figuring out how many bars you need isn’t a one-size-fits-all equation. A structural engineer or experienced concrete contractor will look at your slab’s thickness, the loads it must carry, and local code requirements, then run the numbers for you. That quick consultation protects your budget and keeps the finished slab safe, level, and up to code.
Match the metal to the job. For light, thin pours like a sidewalk, welded wire mesh often does the trick. Thicker slabs—driveways, garage floors, foundations—usually call for traditional steel bars. If your site sees salt, humidity, or coastal spray, spend the extra cash on galvanized or stainless steel to fend off rust and avoid future repairs. When in doubt, a concrete pro can confirm the best fit for your project and budget.
Stainless steel costs more up front, but the alloy can last 75 years or longer with little to no rust. That longevity means fewer repairs, less maintenance, and peace of mind for structures exposed to salt, moisture, or de-icing chemicals. If you’re pouring near the coast or in a humid climate, the extra dollars now can save you multiple replacements down the road.
An engineer will review the slab’s thickness, span, soil conditions, and expected loads, then specify bar size, spacing, and grade. Skipping that step or guessing can leave you with cracked concrete or a blown budget. For a modest consultation fee, a local engineer or contractor can do the math and hand you a rebar schedule that meets code and keeps your project on solid footing.
