Best method for sealing a rock and concrete pond?
Question:I have a pond that is made up of natural rock with what appears to be ordinary cement used to seal between the stones. The builder placed a tube near the bottom of it for a water feature and built up around this tube with stone. so I can't use a liner. The pond is leaking between the joints in the cement. I am not planning on putting fish in at this time, but would like to add some plants. What would be the best material to coat this entire surface with in order to make it hold water. The pond is located in Connecticut and is about 2 1/2 feet deep x 3 feet long x 2 feet wide and holds about 100 gallons of water give or take. Thanks in advance.
Answers:
Go to lowes or homedepot and then visit thier building materials department they carry a sealant just for this case.
I would suggest a non-toxic polyurethane sealer.You may have to use something like poly-filler first to seal cracks in concrete.You can also get a suitable Acrylic paint for ponds, but not sure on that one. Ask your paint/hardware store. Good Luck!
You can use a spray-on liner for ponds.
Contact a pond contractor and they can guide you.
