With a pool deck I start by looking hard at the old surface, because if the concrete underneath is solid, resurfacing can save you a tear-out, and if it isn't, a new top won't last. For a new pour, our crew breaks out the old deck and hauls it away. Then we dig past the soft dirt and pack the subgrade, the ground the slab sits on, so it doesn't settle later. We set the forms so the deck sheds water away from the pool and your house and place rebar, steel bars that tie the slab together. Then we pour early in the day, before the heat can dry the top too fast and leave it weak and dusty. We lean toward finishes with good footing around the water, and we cut control joints, shallow grooves that give the concrete a planned place to crack, while the timing is right instead of days late. Before any of that, we talk through how the pool's electrical bonding fits into the schedule. Bonding is the wiring that ties the metal parts together and helps cut down shock risk, and it usually has to be in place before concrete goes over it. If the budget gets tight, I'd rather you go simpler on the finish than cut the base. The finish is what you see on day one, but the base decides whether the deck is still flat years from now.
A pool deck rarely stands alone. If your yard steps down from the house or a patio to the pool, we can build the concrete steps in the same job so the heights and the finish match. If you're adding a pool house or cabana, our slab foundation building work gives it a level, solid floor to sit on.
Resurfacing a sound deck
This suits a deck that's still flat and solid but looks tired, stained or rough, because a new surface can freshen it without the cost and mess of a tear-out. It only works when the old concrete is in good shape, so I won't suggest it for a deck that's sinking or breaking up.
Tearing out and pouring new
This is the right call when sections have sunk, lifted or cracked wide, since those problems usually start in the ground and a coating can't fix the ground. It costs more, but it's the only way to dig out, rebuild the base and get the slope right around the pool.
