Hello everyone,
I’m currently working on a pond project and I’m facing a challenge. My pond is approximately 8x4 meters (26 X 13 feet) in size and almost 2 meters (79 inches) deep at the deepest end, average depth of about 80 centimeters (32 inches). I was planning to use sodium bentonite as a sealant but due to space constraints, the slopes of my pond are steeper than the max recommended 1:3 ratio (V:H) for using sodium bentonite as a sealant.
From what I’ve read, sodium bentonite is not a good option for me as it tends to creep downwards on steeper slopes. If I were to follow the recommended slope for bentonite, I would have to reduce the depth of my pond to just 67 centimeters (26 inches), which is not good since I live in a region where freezing temperatures are common, thus maintaining a deeper pond is crucial.
I came across a comment on YouTube suggesting to use 10-20% Portland cement mixed with clay or soil as an alternative method to seal ponds with steeper slopes. Has anyone here tried this method?
Please note that I’m not interested in using pond liners, ducks, or pigs for this project. Any other advice or suggestions regarding using natural materials to seal a pond with steep slopes are greatly appreciated!
