Can a gas line run under a concrete patio or under a deck?
Yes — a gas line can run under a concrete patio or beneath a deck, but it has to be done to code with the right materials and protection. Buried lines use outdoor-rated pipe, sleeved where it passes through or under concrete, at proper depth, with a tracer so it can be located later. Under a deck it's supported and accessible. Best of all, plan it before the concrete's poured.
The right way under hardscape
A buried gas line under a patio uses outdoor-rated pipe, run at proper depth and sleeved where it passes under or through the concrete so the slab never bears directly on it. A tracer wire goes in alongside it so the line can be located later, and there are no unprotected joints buried under the pour. Done to those standards, a line under concrete is safe and lasts — it's routine work for a licensed gas contractor.
Plan it before the pour
The easy version of this job happens before the concrete exists. Roughing in the line — or at least a capped stub — while the patio is still open ground costs a fraction of reopening a finished slab later. If a fire pit or outdoor kitchen is anywhere in your plans, get the gas in during construction. For patios that are already poured, we bore or trench around and under them rather than tearing them up, but it's more work.
Under a deck, and keeping it safe
Beneath a deck, the line is supported, kept accessible, and protected from damage, with the shutoff within easy reach. Wherever it runs, we mark it so a future landscaping project doesn't put a shovel through it. And like every line we run, it's permitted, inspected, and pressure-tested before it carries flame.
