Ground, design and permits for a new slab
The Census Bureau's 2020–2024 survey estimates date about 17% of Lorena's housing units to 2000 or later, and 4 of them to 2020 or later. When McLennan County's 1992 soil survey described its typical Stephen silty clay, it chose a spot 0.6 mile northwest of the Farm Road 1695 and Farm Road 2837 intersection in Lorena. Stephen soils are very shallow or shallow clayey upland soils over chalky limestone. One sample doesn't describe every lot, and the same survey says foundations should be engineered according to soil properties.
Where the design calls for post-tensioning, the Post-Tensioning Institute credits it with using less concrete and steel for equal capacity and with keeping cracks tight. PTI's design guidelines for these foundations date from 1980 and have since been used on millions of residential foundations. No design makes a slab crack-free, though: in the American Concrete Institute's slab-on-ground guide, owners are to be advised that some cracking and curling is normal on any project.
Lorena's permit list covers new construction, additions and accessory buildings, so check with City Hall before the slab is scheduled. A larger business building fits commercial slabs and floors, the drive out to a new garage or shop fits a concrete driveway in Lorena, and our Lorena concrete page lists the rest.

(254) 309-9254Setting out, steel and the pour
Ground and design
The soil, the loads and the building decide between rebar and post-tension, and whether an engineer designs it.
Permit, base and steel
With the permit in hand, the base is compacted and the steel set; the 2015 International Residential Code calls for a 4-inch base course where a floor is below grade.
Place and cure
Concrete is placed, finished and kept curing as the design calls for.

Slab questions for houses, shops and sheds
What does Lorena's fee schedule charge for a small accessory building?
The City's 2022 schedule sends miscellaneous residential projects, "such as, but not limited to, Accessory Structures, Fences, Pools, etc.", to Fee Table 2, which prices them by valuation: $76.92 for a project valued at $1.00 to $10,000.00, plus the 15% administrative fee added to table fees. Confirm the line for your building with City Hall.
How far does a post-tension cable stretch when it is stressed?
About 8 inches on a 100-foot cable. Each cable is pulled to 33,000 pounds, one published guide to post-tension basics explains.
How thick is a post-tensioned house slab?
Typically 8 inches, poured with 3,000 psi concrete, with tendons commonly spaced 48 inches on center, according to one published guide to post-tension basics.
