"Rick responded immediately to my e-mail inquiry through the website and called me to set up an appointment. He was extremely professional, courteous and knowledgeable. As it turns out, after making the arrangements for the sump pump, we discovered the source of our water was from our heating system. When we informed Rick of this and the fact the sump pump would not be needed, he promptly refunded our deposit. I would definitely recommend Rick Jackson and will contact him in the future if the need arises.

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.
