Structural Engineers | Concrete Floor Slabs

Simplify the design process and maximize constructability of your design.

PNA’s proven systems help you deliver a durable, reliable and highly serviceable slab. Based on published engineering, PNA tapered plate dowel systems meet exacting tolerances to ensure long-term joint stability for concrete slabs and paving applications. We can provide recommendations for the size and spacing of PNA's plate dowel systems to deliver the industry standard for performance criteria of less than .01 inch (.25mm) of differential deflection across construction and contraction joints.

Strategic placement of steel and materials in concrete flatwork reduces the amount of steel of the project while improving flatwork performance. By eliminating continuous reinforcement and/or extending your joint spacing with PNA systems you can deliver more cost-effective concrete flatwork.

Where to Specify PNA Systems In Your Next Project:

Formed construction and contraction joints in concrete flatwork.

Diamond Dowel® System and PD3 Basket® Assembly
  • Deliver joint stability per industry guides of less than .01 inch differential deflection.
  • Provide positive load transfer.
  • Permit dowel placement six inches from the joint intersection where curling stresses are highest.
  • Minimize joint edge spalling.
  • Ensure joint activation and free horizontal movement to reduce restraint and random cracking.
  • Reduce project costs with material and labor savings.
  • Maximize consistent and efficient constructability.

Edge protection for high-traffic areas, freezer buildings and floor designs where the construction joints are expected to open more than 1/8 inch.

Armor-Edge® Joint Assembly - armored joints to deliver spall-free construction joints for minimal long-term slab and lift truck maintenance cost.
  • Ensure complete joint edge protection.
  • Provide smooth surface transitions to reduce lift truck damage and maintenance.
  • Allow joint activation without restraint, minimizing cracking.
  • Spall-free construction joints for the life of the floor.

Gradual, uniform and controlled curing environments for durable slab surfaces.

HydraCure™ Moisture Cure Covers - wet curing covers to improve slab appearance and abrasion resistance.
  • Control environment with optimal hydration and drying rates.
  • Compatible with surface treatments.
  • Reduce cracking, crazing, scaling, dusting and pop-outs.
  • Result in residue and stain-free slabs.
  • Increase abrasion resistance.
PNA can streamline your next flatwork project with published engineering, submittals and replicable specifications for concrete flatwork projects.
