PD3 Dowel Cradle

The patented PD3 design features a tapered and sleeveless plate dowel that provides the world’s best performance in limiting joint deflection to provide superior joint stability.

The PD3 design features a tapered and sleeveless plate dowel that provides the world’s best performance in limiting joint deflection to provide superior joint stability. The PD3 dowel provides the highest deflection control tolerance in-line with ACI Standards recommendations to limit joint spalling, facilitate load transfer and provide the lowest risk of restraint to ensure the best serviceability outcome for the slab design. For simple construction, the PD3 dowels are positioned at preset heights and spacing in the cradles that are easy to carry and place.

• Plate dowels alternate to maximise percent of steel at the joint, and provide generous installation tolerances.
• De-bonding material allows for close steel-to- concrete contact and allows shrinkage without restraint, eliminates need for a plastic sleeve.
• Wire cradle ensures dowels are at the correct heights and centre spacing.
• PD3 cradles are 2250 mm long with 5 dowels spaced 500 mm apart. Dowel plates are available in 6 mm or 10 mm thicknes

Benefits:

• Simple installation with generous tolerances and no need to stake to sub-base
• Easy to carry cradles
• Effective joint performance: reduced out of joint cracking, and less faulting and spalling
• Better performing concrete floors and pavements
• Improves customer satisfaction: less repairs and maintenance
• Repeat business
• Business differentiation

• Compliance with TR34, TR66, ACI 330.2R-17, and ACI 360R-10
• Performance engineered design: provides highest performance in controlling joint deflection and minimises restraint
• Reliable and predictable joint performance
• Simplified installation on-site ensures that design specifications and tolerances are met
• Value engineering: allows for designs that optimise materials

• Long life-cycle pavements and slabs
• Increases tenant satisfaction
• Reduces floor maintenance and downtime costs over the lifecycle of the facility
