A Concord patio gets long, dry summers and a few wet months. We size it for how you use the yard, separate it from the house with an isolation joint and pitch it so rain runs off. Lighter colors stay cooler underfoot.
A patio in Concord gets used most of the year, and it also takes a lot of sun. We ask where the afternoon shade falls, how you move from the kitchen to the yard, and what will sit on the slab. A dining table needs a different size and shape than a spa or an outdoor kitchen. Then we look at the ground. Back yards in the Diablo Valley are mostly clay, and many were watered for years as lawn, so the top layer is soft. That layer comes out and compacted rock goes in.
The joint against the house is the detail people never see and always benefit from. We set a compressible strip between the patio and the foundation so the two can move apart and together as the clay changes with the seasons. The slab is kept below the door sill and the bottom of the stucco, and it falls away from the wall so winter rain does not sit against the house.
Finish choices are a light broom texture, a smoother hand finish under a cover, exposed aggregate, color, or a stamped pattern. Light colors stay cooler under bare feet in July, and dark colors can get hot. We pour early in the day during the warm months and keep the surface from drying out while it cures. You can walk on a new patio in a day or two and put furniture back after about a week.
Patios in Concord: common questions
Will a concrete patio crack on Concord clay?
All concrete cracks a little as it shrinks. The aim is to control where. A compacted rock base, steel in the slab, joints at the right spacing and an isolation joint at the house keep cracks thin, straight and inside the joints. Keeping the soil around the patio evenly watered also helps.
Does a patio need a permit in Concord?
A plain patio slab on the ground in your back yard often needs no building permit under the state residential code. A patio cover, a raised patio, electrical or gas lines, or a slab in a required setback can change that. We check with the City of Concord Building Division for your address.
What patio finish stays coolest in summer?
Light, plain broom-finished concrete stays the coolest. Dark integral color, dark stain and some sealers hold more heat. If you want a stamped look, a lighter base color with a soft accent is the comfortable choice for a sunny Concord yard.
