Dowel bars are simply precut lengths of round steel that are used to provide a connection between two large slabs of concrete and are widely utilised in situations where large volumes of concrete are being poured in stages. When used correctly, galvanised steel dowel bars give assistance when there is thermal change and or lateral movement of concrete slabs, acting as a load transfer device across the transverse joint between old and new concrete, which not only improves joint stability but reduces the chances and probabilities of cracking of the slabs.
