Our surcrete is barely a year old and has several cracks in it. Two of them run from the flagstone coping out to the yard. One even appears to go right through the coping. I am concerened that if it has this many cracks in one year, what will it look like in three? Anyone have any info. on this? I am wondering if this is typical of this type of decking? The PB is suppose to come out this week to take a look. I would appreciate any insight on this before I meet with PB. Thanks so much
