Kennards Concrete Care have supplied the Hills M2 motorway upgrade team with a specially modified polyplaner.

The modified polyplaner has been playing a crucial role in the Hills M2 Upgrade, the biggest road project presently being undertaken in Sydney.

The Schibecki polyplaner is being used to scarify the edge of the existing concrete roadway to enable better bonding with new pavement.

Kennards Concrete Care modified the machine to cut into the vertical face vertically rather than horizontally. The skids were also relocated so that the head could float along the top of the pavement.

The upgrade project will widen the existing road between Windsor Road, Baulkham Hills, and Lane Cove Road, North Ryde, delivering four new ramps to improve access to the motorway and is expected to be completed in the first half of 2013.

James Stewart, Project engineer for the paving team, explained that scarifying using the polyplaner has enabled a mechanical interlock between the two concrete faces.

The machine was being used on both sides of the existing paving, and the total length to be covered was nearly 40km.
