Runway Maintenance?

I’ve heard from a couple of people that the petromat needs staples and/or more tar sealant to fix lips or gaps between the rolls of petromat on the runway. I was out there last Saturday and Sunday and didn’t notice anything new. The only possible maintenance I see the need for is, perhaps, to sweep or wash the dirt off the western side. Has anybody else seen something there I have missed or know where these lips in the runway are?
