Dowel Bar Sleeves
Material: High-grade PVC
Diameter: 12mm, 16mm, and 20mm
Length: 300mm - 450mm
Dowel Bar Sleeves are used to reduce the frictional resistance present when using dowel rods to connect two or more concrete slabs.
Sleeves are manufactured from flexible high-grade PVC. Supplied in boxes of 100no.
- 12mm x 450mm
- 16mm x 300mm
- 20mm x 300mm
Stock diameter and length dowel bar sleeves are maintained all year round.

A more effective alternative to using epoxy coating on dowel rods, dowel rod sleeves allow concrete to expand and contract with ambient temperature. This reduces the transfer of stress on parts of the concrete and therefore helps to minimalize the chances of cracking occurring due to temperature fluctuations.
In reinforced concrete slabs, dowel bars are inserted in between layers of reinforcement mesh at (approximately) 300mm centres. To be effective, only one half of the dowel rod is debonded (i.e. encased in a sleeve). The other half is not treated and will remain fixed in place within the concrete.
The length of dowel used depends on the particular joint method; contraction joints require shorter dowel rods and therefore bar sleeves, than expansion joints.
