Slabs That Stay Flat on Soft Ground
Concrete slabs carry everything from a riding mower to a pickup to a standby generator, and in Baton Rouge they sit on ground that moves with the seasons. Clay that swells when wet and shrinks in a dry spell will tilt a thin slab poured on loose fill, and water pooling at the edges makes it worse. A slab that stays flat starts with removing soft soil, building a compacted base, and choosing a thickness that matches what will sit on it.

Generators and storm season
Hurricane Gustav struck Baton Rouge on September 1, 2008, with winds over 100 miles per hour. Wikipedia calls it the worst hurricane ever to hit the area, and the city was shut down for five days. Standby generators are a common addition in a city with that history. The City-Parish residential permits page lists generators among the typical situations that require a permit, so the pad is usually scheduled to fit the installer's plan and inspection. We pour it level, at the size the installer specifies, and set so water drains away from the unit.
Sheds, shops and the 200-square-foot line
The City-Parish residential permits page lists any accessory structure over 200 square feet among the situations that require a permit. That covers many shops, larger sheds and detached garages. If your building is near that size, we look at the requirements for your address before pouring, because the slab often has to match the approved plans for setbacks and size.
Thickness, reinforcement and base
HomeGuide's slab guide says shed slabs are usually about 4 inches thick and often unreinforced, while two-car garage floors typically use reinforced concrete 4 to 6 inches thick. A shop that will hold a vehicle lift or heavy equipment needs more. Under enclosed buildings, a vapor barrier helps keep ground moisture from coming up through the slab, which matters in a humid climate where tools and stored goods can rust or mildew. Edges are often thickened to carry walls and to resist the soil movement that starts at the perimeter.
Getting the height right
On many lots, the right finished height for a slab is a drainage question. A shop or shed floor should sit high enough that rain runs away from the doors instead of in. If your property took on water in 2016 or in a heavy storm since, tell us where it reached so we can plan the slab height and slope with that in mind.
After the pour
HomeGuide's slab guide says a slab is walkable after 1 to 2 days, ready for vehicles after 1 to 2 weeks, and fully cured after 28 to 48 days. Building on a slab, or setting a heavy generator on it, should follow those timelines. We give you the dates in writing.

Concrete Slabs Questions
How thick should a garage or shop slab be?
HomeGuide's slab guide says two-car garage floors are typically reinforced and 4 to 6 inches thick. A shop with a lift or heavy equipment needs more, and we size it to the load.
Do I need a permit for a shed or shop?
The City-Parish residential permits page lists any accessory structure over 200 square feet among the situations that require a permit. We check the rules for your address before pouring.
Can you pour a pad for a standby generator?
Yes. We pour it to the size and height the installer specifies, level and drained, and schedule it around the installer and any inspection.
How soon can I build on a new slab?
HomeGuide says a slab can take foot traffic after 1 to 2 days and vehicles after 1 to 2 weeks, with a full cure at 28 to 48 days. We give you dates for your slab.
