My coping is a 3 inch thick x 9 inch long and my pool gunite beam is a 12 inch long. I have a 3 inches of beam exposed? Will I be safe to pour concrete over the beam? I have the 3 inch foam m.r meadows deckoseal expansion joint going behind my coping. I been reading a lot of people chip the beam out. I don’t really want to do that to my pool. Thanks
