I have a basin constructed of cement block 24 inches square and 14 inches deep There has been an epdm liner in it but it has recently chosen to leak. I am in the midst of removing the drilled basalt column and poured in place concrete base. My question is of the most cost effective material to resurface/waterproof the interior. My thoughts run from Sani-tred to paint on stuff to tile, but never having done anything in this area I am at a loss. I would really appreciate some insight from experienced pond/fountain folks.
No I didn't Shella. I picked up some coating at Home Depot that is supposed to seal cement. It requires a tile covering though to protect it from abrasion. That is fine since I was going to tile the outside anyway and now the inside will match. Got the tile yesterday and will have the sealer on tomorrow (?) and maybe start tiling Monday.
Thank you Gourd. The material I found at Home Depot is called Redguard, an elastomeric stuff from Custom Building Products in Seal Beach, Cal. It should be as good as any of the other similar sealants. I'll find out in a couple days.
Be careful what you choose to use if you plan to have fish or live plants in the basin. There is a product called 'Pond Shield' that is non-toxic, but quite pricey. It comes in clear or many colors. The website is http://www.pondarmor.com It's advertised as "a non-toxic epoxy sealer designed especially for koi ponds, water gardens, fountains, and waterfalls."
