Diamond Dowel® System


Tapered plate dowels for formed construction joints.

The industry standard for construction joints, the Diamond Dowel® System achieves superior joint stability measurements of 0.01 in (25 mm) and delivers reliable, maintenance-free and serviceable concrete flatwork. With the proven Diamond Dowel® System you can optimize materials, reduce labor costs, improve worker safety and minimize joint spalling and random cracking.

Recommended for formed construction joints in:

  • Concrete slabs on grade
  • Concrete pavement
  • Concrete flatwork exposed to pedestrian traffic

With the proven Diamond Dowel® System, you provide the joint stability, positive load transfer and continuity of surface profile your projects demand. The Diamond Dowel® System consists of the tapered plate dowel, sleeve and installation template. The Diamond Dowel® tapered plates are available in three sizes (depending on the loads, wheel type and repetition):

  • 1/4″ (6mm) – typically used in 5″- 6″ slab depths
  • 3/8″ (10 mm) – typically used in 7″- 8″ slab depths
  • 3/4″ (20 mm) – typically used in 9″ plus slab depths

The Diamond Dowel® System is optimal for formed construction. Contact PNA for size and spacing to suit your design and slab type.
