OK, here goes:
I have a small concrete room that is completely underground next to the house. This concrete room is accessible from the outside as well as the basement. I have a septic riser collar that sits around the outside access hole, currently covered with a PT 3/4" lid. I use this room for firewood storage as my stove is in the basement.
I had a helluva time getting the outside access hole sealed where the riser meets the roof of the room, but 5 tubes (joking) of silicon later it is now 100% waterproof. My next problem came when we had 3-4 days of steady rain and the wooden lid became saturated and began leaking.
Looking for some ideas on the best way to waterproof the lid, inexpensively. Lid is approx 30" (same as septic lid). First though was a piece of rubber roofing, but I'm having a hard time finding a scrap piece.
I'm sick and tired of the leaks and rework...want to do it right and be done with it forever.
