Double tee slabs are produced on long line casting beds, normally 100 m to 150 m long (300 ft to 450 ft). Bulkheads are placed to form the required double tee lengths for individual projects. Pretensioning strands and carbon steel reinforcement and connection hardware are placed in the form to suit individual slab requirements prior to placing the concrete. Applications Double tee slabs are available from CPCI members all across Canada. Double tee slabs can be used for most applications requiring a long span floor or roof system (10 m to 30+ m) and/or additional load carrying capability. Double tee slabs are resistant to moisture and corrosion. Parking garages, office buildings, commercial buildings, gymnasiums, pool roofs, food processing plants, paper mills, industrial buildings, and sewage and water treatment plants are all ideal applications. Slabs can be cantilevered at one or both ends for up to 4 times the slab depth. Consult your local CPCI member for specific design assistance with cantilevers.
