Why Concrete

Concrete is the most popular patio material in America. Reasons: extremely durable (lasts 25-50+ years), low maintenance (occasional sealing and cleaning), versatile (can be stamped, stained, colored, or polished), cost-effective ($6-$15/sq ft installed for standard, vs. $12-$30/sq ft for pavers), and strong (supports heavy furniture, grills, and hot tubs). A well-built concrete patio is a one-time investment that requires minimal upkeep.

Design Options

Broomed finish: The standard concrete finish. Textured with a broom while wet for slip resistance. Clean, simple, and the most affordable. Cost: $6-$12/sq ft.
Stamped concrete: A pattern is stamped into the wet concrete to mimic stone, brick, slate, or wood. Colored to match the pattern. Very realistic. The most popular decorative concrete option. Cost: $12-$20/sq ft.
Exposed aggregate: The surface is washed to expose the aggregate (small stones) in the concrete. Natural, textured look. Good slip resistance. Cost: $10-$18/sq ft.
Stained concrete: Acid stain or water-based stain applied to cured concrete. Creates rich, variegated colors. Can be combined with stamped patterns. Cost: add $2-$5/sq ft to the base concrete cost.
Colored concrete: Integral color (pigment mixed into the wet concrete) or color hardener (applied to the surface). Uniform, permanent color throughout the slab. Cost: add $1-$3/sq ft.

Thickness and Reinforcement

Standard residential patio: 4 inches thick. If the patio will support a hot tub or heavy structure: 6 inches thick. Base: 4-6 inches of compacted gravel (provides drainage and prevents frost heaving). Reinforcement: wire mesh (welded wire fabric, placed in the middle of the slab) or rebar (#4 rebar on 18-24 inch centers for larger slabs or areas with heavy loads). Fiber reinforcement (fiber mesh mixed into the concrete) helps prevent surface cracking but does not replace structural reinforcement for larger slabs. Control joints: saw-cut or tooled into the surface within 24 hours of pouring. Spacing: every 8-12 feet (or the slab thickness in feet × 2-3). Control joints control where the concrete cracks (it will crack along the joint instead of randomly).

Pouring Process

Excavate the area (remove sod and topsoil, dig to the depth of the gravel base + 4 inches of concrete). Compact the subgrade. Add and compact 4-6 inches of gravel base. Build forms (2x4 lumber staked around the perimeter, set to the desired height and slope — slope the patio away from the house at 1/8 inch per foot for drainage). Place reinforcement (wire mesh on chairs/supports to keep it in the middle of the slab). Order concrete (calculate: length × width × thickness in feet, divide by 27 = cubic yards needed). Pour, spread, screed (level with a straightedge), bull float (smooth the surface), and finish (broom, stamp, or expose aggregate). Cure: keep the concrete moist for 7 days (spray with water or apply a curing compound). Do not walk on it for 24-48 hours. Do not place furniture for 7 days. Do not drive on it for 30 days.

Costs

Basic broomed concrete (per sq ft): $6-$12 installed.
Stamped concrete: $12-$20/sq ft.
Exposed aggregate: $10-$18/sq ft.
Typical patio (300 sq ft, broomed): $1,800-$3,600.
Typical patio (300 sq ft, stamped): $3,600-$6,000.
DIY (300 sq ft, basic broomed): $800-$1,500 (concrete + materials, but requires significant labor and equipment).
