How to Seal Leaks in a Concrete Pond


A concrete pond is an attractive garden feature, and provides a good talking point when you have guests. However, if the tank has not been properly sealed, there is a risk it could leak, causing costly damage. The easiest way to avoid or repair a leaking concrete tank is to apply a few layers of concrete sealant to the interior of your pond. This is a relatively straightforward process, carried out using products and tools available at many hardware stores.

Things You'll Need

  • White wine vinegar
  • Mop
  • Water
  • Hose
  • Concrete sealant
  • Paintbrush
  • Rubber gloves
  • Face mask
  • Vacuum cleaner
  • Drain the pond of all water, and leave it to dry for 12 hours.

  • Remove any dirt and debris using a vacuum cleaner.

  • Mix 10 gallons of water with 1 quart of white wine vinegar, and use this to clean the sides and bottom of the pool using a mop.

  • Use a hose to rinse the concrete, and leave it to dry for another 12 hours.

  • Use a paintbrush to evenly spread a thin layer of sealant over the concrete. Be sure to wear gloves and a face mask when doing so, as sealant fumes can be dangerous and the chemical is an irritant when it comes into contact with skin.

  • Wait until the layer of sealant has dried, and then apply another coat. Repeat this step once more until you have three coats of sealant on the concrete.

  • Refill the pond, and return any plants or fish to it.
