Adding on to a driveway or patio is one of our most common residential jobs. Here are three San Antonio projects from 2021.
| Location | San Antonio, TX |
| Dates | June, August & December 2021 |
| Concrete | 3000 PSI, 4–5 in. thick |
| Reinforcement | 3/8 in. rebar @ 12 in. OCEW, doweled |
| Finish | Broom |
Patio, driveway add-on and sidewalk, August 2021
Over two days we poured a back patio, a driveway add-on and a sidewalk: 3000 PSI concrete, 4 inches thick, with 3/8-inch rebar at 12 inches each way, doweled into the existing concrete.
Patio with perimeter beam plus driveway extension, June 2021
For this back patio add-on we poured 5-inch concrete with a perimeter toe beam 12 inches deep by 8 inches wide. We also poured a 4-inch driveway extension, both reinforced at 12 inches each way.
Driveway and patio addition, December 2021
We added on to the driveway and back patio with 3/8-inch rebar at 12 inches each way and 4-inch, 3000 PSI concrete.
Why doweling matters
When new concrete meets old, we drill into the existing slab and set rebar dowels. That keeps the two slabs from shifting apart and cracking at the joint.
