Layout, Slope and Connecting to the House
A patio sits directly against the structure, which makes grading the most consequential decision on the job. Water has to move away from the foundation, and the finished surface has to land at a height that works with door thresholds and any existing slab. On flat backyards, achieving usable fall without creating a noticeable tilt underfoot is a matter of careful layout rather than a fixed rule.
Where new concrete meets the house slab or a builder patio, the transition is detailed deliberately — an isolation joint at the structure, a planned joint line at the tie-in, and a decision about whether to match the existing finish or make the difference intentional with a border. New and existing concrete rarely match exactly in color, so a designed transition usually looks better than an attempted match.
Before we pour, we mark the footprint on the ground so you can stand in it with furniture positions in mind. That single step catches more sizing problems than any drawing.
