Pond hippos – and to prevent or cure
If percolating water, ground-water, natural gas, rotting vegetation etc happen beneath your pond liner, you could get a phenomena called “hippoing”. This is where the gas/water can literally push the liner out of the pond. The more gas/water, the more water from within the pond you lose, and strain is put on the liner, potentially resulting in a tear. Through knowledge of the area and pre-design, we can offer solutions to mitigate this from happening. It’s also possible to retro-fit.
