Total Pond Waterfall Foam Sealant really delivers. I used this product for a small water feature. It filled the cracks, maybe a little better than I had planned as it really oozed out. If this happens to you, wait for the foam to begin to set up and then (wearing nitrile gloves) push the excess into the voids you are filling. You can also wait for it to set up then cut the excess off. The only problem I had with the product was the trigger on the application straw broke (both cans) but you can just press the nozzle at an angle and the foam will come out nicely. Just be sure to wear gloves and you will find Total Pond Waterfall Foam Sealant will work for you.

Still waterproof after SEVEN years
I built a waterfall 7 years ago using this produce and a prayer. The foam held for and is still holding. I am re working the waterfalls due to rock breaking down from the flow of water. I purchased this product again to use. **Note: make a pillow of the foam then set the rock.** The best is it is fish safe.
