I was digging out some plants in our landscaping that we don't like and came across a line to the pool. The previous owners had a plant next to the line (thankfully I did not hit it with the shovel!!). It has been covered with dirt, weed barrier and river rock. I am wondering if anyone has any ideas on the proper way to cover this line. Should it be covered with concrete? We live in Nebraska so it freezes in the winter. I will try to attach pictures.
Thanks for your help!!!
