The pool decking is not just to allow access to the water. It will be a place to relax and watch the action in the pool. A place to have parties and maybe include a patio area for BBQ's and outdoor dining.
If your new pool is to be in ground and built in concrete, consider a concrete deck. This type of pool decking is poured at the same time as the pool and forms part of the structure of the pool. It can then either be left as a concrete finish, block paved or tiled depending on your choice and budget. If you tile or pave, be sure to choose something with a none slip finish. If you decide against concrete and prefer a traditional type of decking, there are now specially designed composite boards that look like natural timber but are designed to not get slippery. For above ground pools the decking is constructed after the pool is finished.
Traditional pool decking
For above ground pools, good old timber is still the favorite type of deck. Pressure treated softwood will not last as long as hardwood when it is constantly being subjected to splashing water so I always suggest hardwood if the client is adamant he requires the pool decking in timber. Above ground pools can be decked all the way around if space and budget allows, or can be simply decked at one end with access via a stairway.
Alternatives to timber decks
Other choices are now becoming available when it comes to pool decking. Aluminum, vinyl and plastic are all recent newcomers on the block. A deck built around your pool in one of these materials requires no maintenance, won't ever rot or get bothered by insects attracted by the dampness of a wooden deck.
It will still be a while before these alternative decks become more popular than traditional wood when it comes to a normal deck build but around pools it may only be a matter of time. A wipe down with a cloth every now and then and they come up new. You can even buy them with a timber look imprinted into them so you get the best of both worlds.
Do It Yourself Decking
You can save yourself a a small fortune by building your own deck or patio area. If you are competent with a tape measure, saw and drill you may wish to give the option some serious thought. Before the shovel hits the ground though, find out if there are any building regulations you are rquired to abide by in your town.
