Slab with Standard dowel bar over time

Slab with Precastpro dowel bar over time

  • Most Major Competitors supply 300 grade dowel
  • Precastpro Dowel Bar is supplied in a superior grade strength 350
  • Weaker grades are available on application, for less load sensitive projects that are also price sensitive

Important Tip

  • Dowels increase the initial cost between 5 to 8 percent, but increase the load carrying capacity over 100 percent.
  • The greater the grade of steel dowel the more efficient and stronger the load capacity.

Application Instruction

Step 1

Fix the nailing plate with a nail

Step 2

Slide the conduit into the nail plate, ensuring the plug on the other end is in place

Step 3

Pour slab, Nail plate and plug will prevent concrete leaking into the sleeve

Step 4

FStrip formwork, Nailplate will come off with formwork.

Step 5

Insert the Precastpro steel dowel bar into the sleeve. Half of the Precastpro dowel bar will sit in the Precastpro sleeve, the remaining half will protrude from the concrete slab.

Step 6

Pour slab, Nail plate and plug will prevent concrete leaking into the sleeve

Step 7

The result, the slabs will move while the concrete is contracting. They then return to the original correct position when expanding.
The Precastpro Dowel bar and kit assists to eliminate both slabs, along the joint lines dropping and maintains a level joint.
