A 20×20 concrete slab is a common choice for patios, shed foundations, garages, or small home additions. In Baton Rouge, the average cost typically ranges between $3,000 and $6,000, depending on several key factors. Understanding these factors can help homeowners plan their budget more effectively and avoid unexpected surprises.
Cost per square foot in Baton Rouge
General pricing guidelines
In Baton Rouge, the price per square foot for a concrete usually falls between $7 and $15. For a 20×20 slab (400 square feet), this means:
- Low-end: $7/sq ft x 400 = $2,800
- Mid-range: $10/sq ft x 400 = $4,000
- High-end: $15/sq ft x 400 = $6,000
These ranges include labor, materials, basic site prep, and finishing. Specialty finishes, reinforcements, or thicker slabs can increase the total.
Variables that affect pricing
Slab costs vary depending on soil conditions, ease of access, need for permits, and whether grading or removal of old concrete is necessary. Baton Rouge’s humid climate and clay-rich soil may require added reinforcement, especially if the slab will support heavy structures or vehicles.
Concrete thickness and reinforcement
Standard thickness for 20×20 slabs
A 4-inch slab is typically standard for patios or walkways, but for garages or structures with weight-bearing loads, a 6-inch thickness with rebar is recommended. Thicker slabs and reinforcements raise the price per square foot.
Reinforcement options
Wire mesh and rebar both add strength and longevity to concrete. Including these in your project can cost an extra $1 to $2 per square foot, but it’s a smart investment for long-term durability—especially in Baton Rouge’s variable weather conditions.
