We are getting bids on a pool (gunnite, IG, SWG, 18 K gallons) and with the slope in our yard it looks like we will need an exposed beam of about 2.5 feet on the deeper end of the pool. The pool builder sketched in more decking on the far side. This all sounded great until the "mom" in me started losing sleep about kids slipping on the coping and falling back on the hard decking; visions of concussions abound. We can leave grass as well - but the hubby is wondering what all the splash from the salt water will do to the grass. Nothing? Any experience with either the exposed beam with concrete - safety and/or grass with salt water issues?
