You can't practically cover the ponds. The area is far too big. Here's a grab I took of a pond on their website. Anything that would last would just be epic and cost prohibitive imo.



Regarding the heap itself, I think the cost benefit isn't there in terms of covering it tbh. It's harder and more costly than you would think.
