Use a gasket for waterproof surfaces you wish to preserve or if you are installing on a concrete surface and you live in a climate with freeze thaw cycles. The water seal prevents premature cracking of concrete around the fastener entry points. Made of high quality EPDM rubber for longer life than neoprene. Also creates a thermal break reducing expansion and contraction
