I had a polyurea repair to do in Long Island NY over the last few days. The pond is about 10,000 gallons with one bottom drain, a skimmer and a mid level suction. It was sprayed a year or so ago but the prep work wasn't done perfectly and some of the polyurea started to peel off and clog the drains and skimmers. This pond has a window into the basement which is going to be a living room in the future.
The pond originally had a spin drifter bottom drain installed in it but this drain leaked from the airline so I replaced it with a Rhino II aerated bottom drain. This seemed like the perfect time to replace the drain.
I sprayed the pond in blue first which makes it easier to see any pin holing or misses when I go back over it in black which is the finished color.
I forgot to mention before spraying the new polyurea spray liner the existing polyurea had to be scraped to remove any lose product plus the entire surface was sanded and wiped with primer.
It snowed while I was spraying but this awesome winter cover stopped any of the snow from getting in. This is one of my helpers on the job.
Blue Burst! It looked kind of neat and would make a good color for an aquarium but this pond was going to be finished in depthless black.
This is the black going over the blue.
Inbetween coats I fill any pin holes or inperfections that show up from the rough surface on the concrete.
Finished with the Rhino II bottom drain installed.
This is the view the koi will have from inside the pond.
This is a return and below it is a mid level suction point. Normally these would be placed farther apart but in this case the return was installed after the fact by tunneling under a finished sidewalk and patio so there weren't a lot of options.
The finished product ready to be filled minus the puppy.
