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 industry 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
The Diamond Dowel System provides the joint stability, positive load transfer and continuity of surface profile that projects demand. The Diamond Dowel System consists of the tapered plate dowel, pocket former, 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.
