Permasleeve square dowel bars offer significant benefits over round dowels, with better resistance to bending and shear.  The foam inserts in the dowel sleeve allow horizontal movement in two directions as the concrete contracts, but no vertical movement.  The dowel sleeve also helps to reduce the risks and implications of misaligned dowels.

Benefits –

• Durable, efficient load transfer.
• Allows horizontal slab movement in two directions.
• Does not permit vertical slab movement.
• Reduces risk of dowel misalignment problems. 

Applications –

• Suitable for reinforced suspended slabs, steel fibre jointless slabs, and heavily-loaded thick ground-bearing slabs.
