I have a pool with a hot tub slightly raised from the pool. The spa "spills over" into the pool forming a waterfall. The problem is there is no drip edge so I find a good amount of water clings to the bottom of the spill way and runs down the hot tub siding... the grout in this area slowly being taken away and occasionally I have algae growth in these areas.
Does anyone have experience remedying this problem? I thought about cutting a small gap on the under side of the spill way limestone but that seems very labor intensive and may not even work depending on how fast the water is flowing.
