Concrete Pool Decks in Greenwood, MO

A Greenwood pool deck lasts when the perimeter is thickened into an edge beam that resists curling, the base is compacted over the Wymore-Snead clay, an isolation joint keeps the deck free of the pool shell, and the surface is broomed to grip wet. On clay, the outer edge of a slab is the first thing to lift and crack — so we build strength exactly where a deck needs it.

Greenwood keeps a high standard, from the historic storefronts near the Mercantile to the quieter lots around Lake Greenwood and Greenwood Estates. A deck that curls at the edge shows fast, so the edge detail is where the work goes.

Around the outer edge of the deck and along the coping, we deepen the slab into a thickened edge — a beam that runs the perimeter, dropping the concrete to eight or ten inches instead of the four-inch field thickness, with steel run continuously through it. That beam does two things: it stiffens the free edge so it resists curling, and it carries the slab's load down to firmer ground below the active surface clay.

It is a straightforward detail that most fast-bid decks skip because it costs a little more concrete and steel. On Greenwood's clay it is the difference between an edge that holds its line for decades and one that starts breaking up at the perimeter within a few seasons.

The Wymore-Snead clay swells wet and shrinks dry, so water control keeps the whole deck steady. We slope the deck a quarter-inch per foot away from the pool and the house, and route roof and deck runoff to daylight past the slab. On lots that fall toward Lake Greenwood, we grade with that drainage direction and relieve any low corner with a drain line in stone.

Steadier moisture under the deck means less movement in the clay, and less stress on the very edge we worked to strengthen.

A pool deck is walked wet and barefoot, so we broom it for slip resistance that holds on a wet deck. In a town that keeps its look sharp, many Greenwood homeowners step up to a stamped or stained finish that suits an established lot, with the same traction once sealed.

We seal against Greenwood's freeze-thaw winters, and for a saltwater pool we choose a sealer rated for the added salt exposure, applied dry so there is no sealer blushing. See finished decks in our gallery.
