RiteSeal is a pre-formed low-density, closed cell, cross-linked, polyethylene material. RiteSeal is a flexible, watertight, airtight and chemical resistant expansion joint system. This seismic seal has added UV and infrared ray protection and it is used in new and rehabilitation projects, especially where excellent abrasion, movement capabilities and chemical resistance are required. RiteSeal is manufactured with grooves along the bond surface running the length of the joint. Splicing of the seal is performed using the heat-welding method. Conforms to ASTM D-1056, Type I & II, Class B, Grade 3, AASHTO T-42-84 Modified, & P-604.
