EPS boards contain very small air pockets between the foam beads which expand and contract with changing temperatures. If a board is dinged while surfing and water gets in, additional heat (leaving your board on the beach or in a hot car) will cause the water to change phase in to steam and exert pressure on the fibreglass skin - pushing the glass away from the foam (de-lamination).
