PondSeal

This PondSeal page has changed, please be aware there will no longer be small quantities offered and only large quantities as a request for quote for significant projects or tonnage. Please feel free to read on to learn more about pondseal and listen to the interview. If you have questions about a leaking pond and need help or ideas on how to fix it please use the contact page to let us know how we can help.

Help for your leaking pond is now easier than you could imagine… there is a new product on the block called PONDSEAL. Whether you have a leak in an existing pond basin or are installing a new waterway, PONDSEAL is there and ready to hold your water.

Not that its brand new but truth be told, the technology has been around (as AquaBlok®) for about 10 years now – but it has historically been used for a different reason . . .  to separate clean water from contaminated sediments. Additional formulations and smaller-unit packaging options have introduced a whole new way to fix a leaky pond or to seal areas of gravel, sand, or other porous materials while digging the pond.

Picture this… The pond is all finished, full of water, and you decide to put in a dock, deck, or duck house. Next thing you know the water level is going down because you just put a hole in the pond liner or thru the clay liner. Sodium bentonite clay is a great solution and sealant, but how do you get this fine powder around those poles? The clay is a fine grained powder like baking soda or flour that clumps when it gets wet – so it’s often very difficult to place where you want it.

What if it was like sand where there is some weight behind it and you could easily distribute the material around those poles and know you are hitting the target area – not waiting for the powder to get wet and just hoping that it hits its mark?Leaky Pond

This is where PONDSEAL comes to the rescue. This innovative technology is simply a tiny rock reliably coated with high-grade, powdered sodium bentonite. Picture a peanut M&M with the peanut as the rock and the chocolate candy shell as the sodium bentonite. Due to the weight and structure of this “composite,” now you know when you place the bentonite clay through the water it is actually going where you want it – and need it.

A new pond building project with marginal soils (not up to par for water containment) offers many opportunities to use this product. As an example, when building a farm pond 10 feet deep, it would only take a layer of PONDSEAL one inch thick to seal the entire pond. That works out to about seven pounds of material per square foot.

Some of the other uses for PONDSEAL are to fill in muskrat holes, repair damage from rotted tree roots, patch a leak in a synthetic pond liner, reinforce control structures like overflows, or seal around pipe entering or exiting the basin as an anti seep collar. The material can make all of these projects a lot simpler.

Listen to the audio below, where Darrell Rhoades interviews Eric Kraus to learn more about PONDSEAL, what it is, what it does, and to hear more technical in-depth questions about the product.  Listen carefully to find out if your pond is leaking or if it is just evaporation. If you have a problem, see how simple PONDSEAL is to use. Click the play button to listen to the interview.

Please shoot us an email for a quote as shipping is a factor and to help determine amount you may need. Typical application is 7 pounds per square foot on flat or sloped sides. If the sides are 40 degrees or steeper, it is suggested not to use Pond Seal as it will just roll down to the bottom of the pond.

Available in Palm Beach County Florida ? Looking for smallest package. Thank you.

Smallest package of Pond Seal is 50 bag $34.19 plus shipping. Shipping cost are approx. $1 per pound. It would be cheaper if you could find a dealer more local to your area.

My pond has too much gravel in the bottom and sides. It fills after a 2 or 3 in. rain then leaks out at about1.5 in./day. I would like to seal it.

hanks.

Hi Ken, Does the pond leak all the way to the bottom? Or does it stop at some point? The question is to determine if maybe we have a leak at on the side of the pond or if the entire pond is too porous and leaks out completely to the bottom.

There are three options that I know of to seal a pond. Pond Seal is one of them and there are limitations, steep side wall it will not work on as anything over 40 degrees the pond seal will simply roll down the side to the bottom leaving the sides unprotected.How much Pond Seal would you need? You will need the square footage of the pond including the side walls. Then for an average coating multiply the square footage by 7 lbs per square foot for a total of product. This will also be the weight for shipping by freight.

Using a pond liner could be the answer as well but please read the pond liner page for more information about pond liners. You would figure the square footage of the pond, including the sides times 2 plus a few extra feet for anchoring the liner and shipping as the liner will be quite heavy. Anchoring can be seen on the liner page as well.

Lastly is a product call ESS-13 by seepage control Get a hold of these folks and let them know I sent you. They will help determine the amount of water loss and if their product will be able to work for your situation. The hard part with this product is keeping water in the pond and moving around so it can find the leak and seal it as it leaks through the leaking areas. Bottom diffused aeration is the best method for keeping the water moving and product suspended to be efficient in dealing the pond.

Is this product mainly for fixing leaks or can it be used to build an entire pond? Thanks!

Darrell Rhoades November 7, 2015, 4:07 am

The product can be used for the entire pond to seal. Pond Seal will work as a repair product or lining the entire pond at a rate of 7 pounds per square foot, which is shooting for about 2″ thick of material. I believe that was brought up in the recording on the page above. Depending on the size of pond it could be a large quantity. Another point to look at is the side walls of the pond. If the are 45 degrees and steeper you may not want to use the pond seal as it will slide or roll to the bottom of the pond. Hope this helps.

Our pond leaks from the back somewhere and how much would it cost to buy the stuff to fix the pond. I would like the pond to hold water.

Darrell Rhoades November 7, 2016, 4:12 am

HI Kelly, its hard to get a measurement from what you describe, but in the article towards the end it says “Typical application is 7 pounds per square foot on flat or sloped sides. If the sides are 40 degrees or steeper, it is suggested not to use Pond Seal as it will just roll down to the bottom of the pond.”
Other questions are,
How fast does the pond leak? an inch a week? an inch a day? or more
Does the pond stop leaking at some point? Or does it leak all the way to the bottom?
Has it always leaked or is this something that just happened?
How large is the pond, 1/4 acre
There are other products out there for leaking ponds so depending on how fast it leaks, the steepness of the banks would also help determine the product to use. Pond Seal is only sold by the truck load so shipping will become an issue, along with how you would spread it out, but also the other products will be shipped by truck and would need a fork truck to unload.

Sometimes a you could find the leak if the pond stops at a certain point, dig out the bad area and refill with clay found locally would be the cheapest route to take.
