A 70 +/-5 mils thick, polyester, fiberglass reinforced laminate, polymer modified bitumen based sheet membrane used in conjunction with the Roybond Primer-Adhesive Series. The typical uses are as a waterproofing membrane on bridge or parking garage decks, highways and tunnels where greater elongation is required by agency specifcations.
Royston 10A-65P is a highly advanced waterproofing membrane designed for a variety of applications where durability and flexibility are paramount. This prefabricated reinforced laminate incorporates an impregnated woven fiberglass and polyester blend, providing exceptional tensile strength and puncture resistance. The unique composition features a high-strength inner fabric reinforcement sandwiched between two layers of polymer modified bitumen, making it ideal for environments subject to structural movement due to thermal expansion, contraction, or substrate settlement.
The Royston 10A-65P membrane is manufactured to stringent agency specifications, including elongation requirements that ensure performance in demanding conditions. A distinctive 3-inch leading edge facilitates a secure, positive compound-to-compound seal at overlaps, enhancing waterproofing integrity. For transverse sealing, Royston Flex-Flo Adhesive Sealant (FFAS), Royston 104 Caulkable Mastic (104CM), or heat sealing techniques can be employed for added versatility.
The Royston 10A-65P waterproofing membrane is a reliable choice for contractors and engineers seeking efficient and effective solutions for structural protection. Its cutting-edge material technology and proven performance endow it with the ability to withstand extreme conditions, thereby ensuring long-term structural integrity and reduced maintenance costs.
