I start with wet bare feet and the pool edge. Before anything is priced, we go over finishes with you for grip and heat. We also work out the drains and joints before the forms go up, including the flexible joint at the coping. Then comes the part you won't see. We dig out and pack the subgrade, the ground the slab sits on, because a deck raked level over loose dirt settles with it.
When a budget gets tight, people usually want to trim the base first, since nobody sees it once the concrete's down. I'd steer you the other way. If you need to save money, pick a plainer finish, like a broom finish, which leaves light brushed lines that give bare feet some grip. Keep the base. A fancy surface on a settling base cracks right along with it.
Inside the slab we set rebar, steel bars that hold the concrete together and keep cracks from opening wide. We cut the joints on time, because joints cut late or skipped let the slab crack wherever it wants. After the finish, the deck needs curing, which means keeping it from drying out too fast so it gains full strength before chairs and foot traffic go on it.
A pool deck usually ties into other concrete. If yours steps down to the lawn or up to a back door, we can form concrete steps as part of the same job so the heights and the finish match. If you're adding a pool house or cabana, our slab foundation building work covers the slab under it, and we grade both so the water runs the same way.
