Concrete Patios That Drain Away From the House
Concrete patios in Colquitt for homes where the slab needs to match door threshold height and direct water away from the foundation
The two most common problems with a backyard concrete patio are a surface that drains back toward the house and a finished elevation that does not align with the door threshold. Both problems are set in place before the first yard of concrete is poured—they come from how the area is excavated, how forms are set, and whether anyone checked the elevation of the door before establishing the form height. Jax Concrete builds concrete patios for homes in Colquitt, with Josh and the crew managing forming, pouring, and finishing from start to cleanup.
The area is excavated and graded so the finished slab drains away from the structure, and forms are set to the elevation of the door threshold so there is a consistent transition between the house and the patio surface. Concrete is placed, screeded, bull floated, and hand finished before the job is complete. The crew stays through the full finishing process and does not leave the site until the surface is done and the work area is cleaned up. Free estimates are offered before any patio project is scheduled.
Contact Jax Concrete to walk the area and confirm the planned grade and threshold elevation before forming begins.
Getting the grade right before excavation begins requires checking the existing ground slope and deciding where the water needs to go when it leaves the patio surface. The standard is a minimum slope away from the house—typically about 1/8 inch per foot—established through the form elevation before concrete is placed. If that slope is set in the forms, the finished slab holds it. If it is not, no amount of finishing work corrects it after the pour.
Once the patio is complete and cured, the transition from the back door to the patio surface should be flush or stepped down by a consistent amount across the full width of the opening—not higher on one side than the other. The surface should drain visibly toward the yard rather than pooling at the house wall or at the base of a step. Control joints across the slab give water defined channels to pass through during heavy rainfall rather than ponding at random low spots.
Patio size, shape, and whether steps or a landing are included all affect how the project is formed and what elevation decisions have to be made before concrete is placed. Those specifics are worked out at the estimate stage so the finished patio matches both the layout of the space and the height of the door it connects to.
Common Questions About This Service
The following questions address what goes into a correctly built concrete patio—how grade is managed, what the finished work should look like, and how the forming stage sets up the outcome.
How is the slope of the patio surface established before pouring?
Forms are set at elevations that produce the planned slope away from the house before any concrete is placed. The grade is checked at multiple points across the form layout, not just at the edges, to confirm the slope is consistent rather than varying across the slab width.
What has to be checked before setting the form height for the patio?
The elevation of the door threshold is measured and compared to the existing ground level at the house wall. That measurement determines where the top of the form needs to sit so the finished slab transitions correctly to the door—either flush, slightly below, or at a consistent step down—across the full opening.
How does excavation depth affect the finished patio surface?
The excavated depth sets how much concrete can be placed while still hitting the planned finished elevation. Too shallow and the slab comes up higher than the threshold; too deep and extra concrete is needed to fill the void, which can affect consistency if the base is not uniformly compacted after the dig.
Why do control joints matter on a backyard patio specifically?
A patio slab adjacent to a house sits in a constrained position—the house wall on one side and open soil on the others. Concrete wants to move as it cures and as load is applied over time. Control joints give that movement a directed path so any cracking follows the joint line rather than crossing the slab face in an uncontrolled direction.
What does a correctly finished patio surface feel like and look like underfoot?
A broom finish provides consistent traction without being rough enough to catch debris and hold it. The surface should feel flat under a straightedge—no rocking or flex—and the edges where the slab meets the house wall or any landscaping border should be clean and formed squarely, not ragged from form removal.
