Cracked concrete pond
Hi
I have a small pond (7' x 5' x1') with deep cracks in it. Pond water gradually drains through the cracks. Does anybody know how to repair these cracks and make the pond waterproof again? Thanks in advance Bonod |

I used a bitumen based sealant. Warmed it up to make it more liquid and
chose a hot sunny day so that the concrete was warm. Brushed as much dust from the gap as possible and allowed the sealant to run down the cracks. I then spread the sealant away from the cracks to make a T shape over them (the downstick of the T is down the crack). Allow the sealant to cure for a couple of days, then cover with pond paint, preferably over the whole pond and a couple of coats. No sign of a leak in a couple of years now. Make sure that neither the sealant nor the paint has any kind of bactericide or algicide included or it will poison the pond. You might like to make sure that the reason for the cracks has gone away for good though or the stresses may return to create new cracks. In my case it was a large tree root that had grown directly under the middle of the pond. Good luck. "Bernard Huckstep" wrote in message ...

Hello Bernard BH I have a small pond (7' x 5' x1') with deep cracks in it. BH Pond water gradually drains through the cracks. Does anybody BH know how to repair these cracks and make the pond waterproof BH again? Drain and dry the area. Apply PVA (mixed 4-1 water/pva), let it dry. Patch with 3-1 sand/cement with PVA added. Couple of coats of pva over the top when it's dried. If they're hairline cracks, use bitumastic emulsion or any other rubbery sealant that's good for concrete. Of course, this won't last very long. The big problem is whatever's caused those cracks to appear, probably soil being washed out from the footings. Could also be due to ice, bad concreting, insufficient concrete, lack of proper reinforcement. Guess you've learned the main drawback of concrete ponds. I use concrete a fair bit, but I also line with butyl first. The only real solution is to rip the whole thing out and re-do it. -- Simon Avery, Dartmoor, UK Ý http://www.digdilem.org/ |

Where do you live (that is where is the frost line... how far down does your
ground freeze in the winter)? A 1 foot deep pool almost anywhere other that the south were it doesn't freeze is going to get a lot of stressed put on it during the freeze and thaw of a normal winter. I would think anything you would seal the cracks with would not last over the winter and have to be redone every spring. The pond liner for that size of pond would be inexpensive and would be easy. The problem would be the aesthetics. DK "Jerrispond" wrote in message ... I have a small pond (7' x 5' x1') with deep cracks in it. Pond water gradually drains through the cracks.
