Begin with use, not just dimensions
Sketch where the table, grill, seating, doors, and walking paths will go. A patio can look large on paper but feel tight once furniture and circulation are considered. Note hose bibs, utilities, downspouts, septic components, trees, fences, and future structures before the layout is finalized.
Transitions and thresholds
The patio elevation must relate carefully to doors, steps, siding, foundations, and the surrounding yard. Water should move away from the building without creating a difficult step or sending runoff toward a neighbor. Exact slopes and elevations should be determined at the property.
How thick should a patio be?
There is no responsible one-size answer. Use, soil and base condition, loads, freeze-thaw exposure, local practices, and whether the slab will support a structure or heavy feature all matter. A simple pedestrian patio may differ from a slab intended for a hot tub, outdoor kitchen, fireplace, or future enclosure. Equipment manufacturers and project professionals should confirm requirements.
Finish options
Broom-finished concrete is textured and straightforward. Stamped patterns create a more decorative surface but require careful layout, coloring, sealing, and maintenance. Stains change color while retaining the concrete’s character. Borders and saw-cut patterns can add structure without covering the entire patio in a decorative treatment.
Details to put in the scope
- Layout, dimensions, curves, and transitions
- Excavation, base preparation, and access
- Thickness, reinforcement, and joint approach
- Drainage direction and nearby downspouts
- Surface finish, color system, and sample expectations
- Steps, edges, sleeves, or planned utilities
- Curing, sealing if applicable, and use instructions
If a roof, enclosure, hot tub, fireplace, retaining condition, or other structural feature is planned, say so before the slab is designed. Additional review or permits may apply.
