Smooth Form Finish: PS1 plywood intended for concrete formwork, edge sealed, no mill <br />oil. Type B-B Plyform, MDO or HDO overlain plywood. <br /> <br />1. Where finish is exposed to view in completed construction, use only overlain <br />plywood. <br /> <br />C. Architectural Concrete: [HDO plywood made specifically for forming Architectural Grade <br />Concrete. <br /> <br />D. Foam Filler: ASTM C578; Type IX expanded polystyrene, or Type VII extruded <br />polystyrene foam. <br /> <br />2.2 ACCESSORIES <br /> <br />A. Form Ties: Snap off metal tie of fixed length with plastic cone, designed to prevent <br />spalling of concrete upon removal. Provide units that will leave no metal within 1-inch <br />(25 mm) of concrete surface. <br /> <br />B. [Waterstop Type 1: Flexible PVC (polyvinyl chloride) Waterstop as manufactured by <br />Greenstreak, profile style number 771, or equal.] <br /> <br />1. The PVC Waterstop shall be extruded from an elastomeric plastic material of <br />which the basic resin is prime virgin polyvinyl chloride. The PVC compound shall <br />not contain any scrapped or reclaimed material. <br /> <br />2.
