Proven Load Transfer System

Achieve superior load transfer at construction joints with the original plate dowel system. Since 1997, contractors and engineers have used the Diamond Dowel^® System in more than one billion square feet of concrete slabs-on-ground to deliver the durable, maintenance-free concrete flatwork customers expect.

The Diamond Dowel^® System helps you:

• Collect retainage
• Reduce call backs
• Save labor
• Optimize the amount of steel in a project
• Deliver serviceable slabs-on-ground
• Shorten construction schedules

Design Advantages

• Diamond-shaped tapered load plate allows the slab to move horizontally in all directions without restraint
• The tapered shape and the Diamond Dowel^® pocket former allow for 0.375 inch of lateral movement at a joint that opens 1/8 inch
• Provides 6.36" at the joint where the bearing, shear and flexural stress are the highest
• Limits differential deflection across joints to minimize joint spalling
• Can be located up to within six inches of a joint intersection

Installation Advantages

• Reduces labor costs by at least 50 percent when compared to round dowel installation
• Bulkhead stripping is made simple; there are no dowels to spin and remove
• Use the Diamond Dowel^® installation template to reduce labor by a further 50 percent and ensure perfect alignment
• The plate does not penetrate the bulkhead and no bulkhead drilling is required
• The pocket former has internal collapsible fins that hold the diamond-shaped plate in the correct position and creates a void to its inside vertical faces
• High density plastic pocket former will not compress significantly under the vertical load and will not therefore impact the load transfer capacity
• Use of locally available wood bulkheads reduces lead times and freight costs. The Diamond Dowel System^® pocket former and plate dowels are available through our national distribution network.

Note: Refer to the PD³ Basket^® assembly section of the web site for dowel size and spacing for saw-cut contraction joints.
