What's your concern with wood ? Rotting ? If its properly installed and sealed from the begin and maintained over the years you shouldn't have a problem

how do u properly seal wood from the beggining? whats the best thing to do to make a proper wood floor?

To start the design needs to be well done. theres need to be enough separation from the ground not to trap moisture. the separation between boards should be a minimum of 1/16 of a inch preferably 1/4 inch this will help with drainage and also good design would be proper sloping to insure water doesn't run towards the home or also pooling on the deck. and when laying wood on wood or butting up to wood a wood preservative should be used and all sides of the wood should be sealed with a stain or wood oil even including cut ends before laying it in to place. Also using a hard wood like ipe ot tiger wood would be best around pools.

What are the dimensions of the concrete pads? Also, what is the spacing between them? Thanks!

Please let me know the type of wood and finish? This pool is stunning!
