What do you guys like to use to seal off storm drains? I have been using sand berms but I was at cosco last night and they are selling these rubber kitchen mats that are quite thick and made out of something that is rather gooey for lack of a better word. I don't know how durable they are but I think with a little weight on top it will seal up well. I picked one up and was thinking I would cut some 1/8 plate the same size and glue them together and throw it on top of the drain.
