Concrete Contractor in Coronet, Plant City

Coronet, the phosphate company town on County Road 574A

The county's historic resources survey places Coronet about five miles southeast of Plant City along County Road 574A, Coronet Road. Coronet Phosphate Company incorporated in 1906 and began mining in 1908. Between 1908 and 1911 its carpenters built 96 worker cottages, and the town also had a clubhouse, tennis courts, a swimming pool behind the director's bungalow of 1912, and a general store that stayed open from 1909 to 1973.

In the mid-1920s the company used up the phosphate around Coronet and moved its mining south toward Hopewell and into Polk County, and by the early 1950s every mine was in Polk. In 1945 the company built a defluorinating plant that made an animal feed supplement. Then the town came apart: from 1958 to 1964 the company houses were sold and moved, most of them to eastern Hillsborough and western Polk. That's a busy past for one patch of ground, and it shapes how we start a Coronet job.

Mined, filled or moved: what a Coronet lot may hide

Three things happened to land around Coronet that don't show from the road. Phosphate was dug around Coronet until the company used it up in the mid-1920s. A company town stood here for half a century, and its buildings came and went. And 96 houses were sold and moved off, which may have left piers, footings or broken slab pieces just under the grass.

None of that rules out a good slab. It means we look first. At the visit we probe the area where the concrete will go and dig a couple of test spots. Florida's residential code wants fill under a slab free of vegetation and foreign material and compacted for even support, so buried debris comes out and clean sand goes back in compacted lifts. If old fill turns out to be soft or mixed, we price the dig-out as its own line. Our Hopewell page goes deeper on mined ground, and the sandy soil guide covers compaction and water. If you've heard your lot held a cottage or a company building, tell us.

Old fill or footings, the county right-of-way permit and tear-out can change the total. Free written estimate after we see the site.

The Coronet Road apron and the county right-of-way permit

Coronet Road is a county road, so a new or replaced driveway that connects to it needs Hillsborough County's right-of-way permit, which covers residential driveway connections and carries a $50 base fee. That permit applies only on unincorporated land. Coronet's mapped center sits outside Plant City limits, but read the Tax District on your Property Appraiser record to be sure, as the city's permit FAQ explains: PC means the city, U means the county.

A company-town past doesn't put you in a historic district. Plant City's Certificate of Appropriateness rules cover its three historic districts, which are the Northeast Residential, Downtown Commercial and Downtown Historic Residential districts inside the city. Coronet isn't one of them. We draw the apron on the site plan, build it to the permit, and keep the swale along the road working so runoff still has somewhere to go. The permit guide has the full county and city steps.

What to Expect, Start to Finish

1. Probe and test spots

   We check the pour area for old fill, piers or slab pieces before we price the base.

2. Parcel and apron

   We confirm the Tax District and draw the Coronet Road apron to the county permit.

3. Line-item quote

   Base work, thickness, steel, joints and the apron, each written out, within 48 hours.

4. Dig out, compact, form

   Debris comes out, clean sand goes in by lifts, and forms are set to drain.

5. Pour, cure, clean up

   We pour, start curing at once and leave the swale and yard clean.

What we write on every Coronet quote

These lines go on the written estimate so you can hold it up against anyone else's.

• Base work. What the test spots showed, and the dig-out and fill price if any is needed.
• Thickness. 4 inches for cars. Concrete Network says 5 inches adds roughly 20% to the concrete cost and nearly 50% to load capacity, so we price it for work trucks.
• Reinforcement. Wire mesh for 4 to 5 inch slabs, rebar on about a 12-inch grid from 5 inches up. NRMCA says fiber cuts shrinkage cracking but can't replace steel or thin the slab.
• Joints. Control joints no more than 10 feet apart on a 4-inch slab, cut a quarter of the depth, plus isolation joints at the garage and walks.
• Apron. Drawn to the county permit where the driveway meets Coronet Road.
• Cure. Curing starts as soon as finishing ends; no cars for at least seven days.
