Concrete Pond Leaking

[smooth_bourbon]

Hi all been a long time I have redone my whole pond with concrete. My dog went for a swim and in climbing out tore the liner. I thought rather then a quick simple patch job I would turn it into a huge drawn out misserable project . So I have a much larger beautiful kidney bean shaped pond, that does not hold water . I have been looking online and found some pound sealer but it ranges from $65 to $165 for 60 square foot, and I will need twice that. What have you used? Any advise very welcome.

Just get an old peice of liner,cut it to shape and then seal the edges to the liner with some of the pond sealent.

http/www.stonetechnologiesinc.com/specials.html - Concrete Sealer X-1 can be used in all commercial and residential applications to treat damp or wet basements, concrete floors, walls, driveways, storage tanks, fish ponds, swimming pools, dog kennels, pipes, blocks, cinder blocks, mortar and stucco. It can also be used to extend the life of exterior wood including fences, patios, decks, cedar and wood shingles.

Unprotected concrete will absorb water which can then leach out soluble constituents and cause spalling when frozen. The combination of outdoor exposure plus water immersion creates a demanding environment for a coating. It must have high resistance to water penetration, be flexible enough to withstand extremes in temperature, and not be affected by ultra violet radiation from the sun. Liquid EPDM rubber coatings possess all this characteristics and are also non toxic to fish.

I've also seen people use the two-part epoxy garage floor "paints" for DIY purposes. They sell it in several different colors now... although the big-box home stores probably just carry yellow or gray. Specialty paint stores like Sherwin-Williams or Benjamin Moore would probably have more color options. The two-part epoxy paint would be the least expensive option.

It's supposed to be EPDM rubber which is the same compound that the better pond liners is made out of so as long as the pond surface is prepped properly, it should work. That's the key to any type of coating product... the prep work.
