A Dallas-Fort Worth patio should sit on a compacted, uniform base, slope away from the house so water doesn't soak the clay at the foundation, and have control joints plus an isolation joint at the house. Plan for summer heat, backyard access over fences or through gates, and HOA review, which is common in newer subdivisions.
Last updated
Many Dallas-Fort Worth homes were built with a small covered slab off the back door, and extending it is one of the most common concrete projects in the metro. Others want a larger patio for an outdoor kitchen, a fire pit or simply room for furniture and shade. The fundamentals that make a patio last here are the same whatever its size: a stable base on moving clay, drainage that keeps water away from the foundation, and joints in the right places.
Planning the patio
- Size for use. Lay out the table, chairs, grill or seating you plan to use and allow room to walk around them.
- Sun and heat. A west-facing slab in a North Texas summer gets very hot. Shade, lighter colors and textured finishes all help.
- Access. Many suburban backyards are fenced with alley-loaded garages, so concrete may be pumped over the fence or wheeled in through a gate. That affects cost and scheduling.
- Future plans. A pergola, patio cover or outdoor kitchen may need footings or a thicker slab, and covered structures generally need a building permit. Say so up front.
Drainage and the foundation
A patio should slope slightly away from the house so rain runs off rather than toward the foundation. That matters more in Dallas-Fort Worth than in many places, because the clay under most homes swells when wet and shrinks when dry, and uneven moisture around a foundation can contribute to foundation movement. Think about where the runoff goes next. A new patio that sends water into a flat corner of the yard or blocks an existing swale between houses can create a new problem.
Base, thickness and joints
Patios are commonly about four inches thick over a prepared base, and many North Texas contractors add rebar to help hold sections together as the clay moves. Soil next to the house is often backfill that can settle if it isn't compacted. Control joints divide the slab into roughly square panels so shrinkage cracks follow the joints. Where the patio meets the house, an isolation joint lets the two move separately.
Tying into an existing slab
Extending an existing patio is common. Some contractors dowel the new slab to the old one; others separate them with a joint so each can move on its own. Both approaches are used, and the right one depends on the soil and the existing slab. Never let anyone drill into the house foundation itself without knowing whether it is a post-tensioned slab, which is common in North Texas homes and can be dangerous to cut.
Finish options
- Broom finish: simple, slip-resistant and economical.
- Exposed aggregate: the surface paste is washed off to reveal stone, adding texture and grip.
- Stamped or stained concrete: patterned or colored to look like stone or tile. See stamped and decorative concrete.
- Light-colored or textured toppings: often used to keep patios and pool decks cooler underfoot.
Permits, setbacks and HOAs
Whether a ground-level patio needs a permit varies by city, and some cities limit lot coverage or building in setbacks and utility easements. Many Dallas-Fort Worth neighborhoods, especially newer master-planned communities in Collin and Denton counties, have HOAs with architectural review for patios and covers. Check both before the pour is scheduled.
Questions to ask
- How will the slab drain, and where will the water go?
- What base, thickness and reinforcement are included?
- Where will joints be placed, including at the house and any existing slab?
- How will concrete reach the backyard, and how will you protect the lawn, fence and sprinklers?

Frequently asked questions
How thick should a concrete patio be?
Patios are commonly about four inches thick over a prepared base, often with rebar in North Texas. Areas that will hold a hot tub, outdoor kitchen or patio cover posts may need extra thickness or footings, so mention future plans.
Can a new patio cause foundation problems?
A patio that drains toward the house or traps water against it can add to uneven soil moisture at the foundation, which matters on expansive clay. Sloping the patio away and directing runoff to a swale or drain helps prevent that.
Do I need HOA approval for a patio?
Many Dallas-Fort Worth subdivisions, especially newer master-planned communities, have architectural review for patios, covers and colors. Check your HOA's guidelines before scheduling the pour, and check with your city about permits.
