Power Plane are the preferred contractor for accurate depth control and this was essential on the recent work carried out on the QEII Bridge on Dartford Crossing.

The contract required the removal of 80mm of surfacing without touching the existing waterproofing. This was especially challenging due to the ''rutting'' in the existing surface. The client did not want the expense of road closures to survey the bridge levels and needed a quick solution that would not impinge on nightly outputs.

Power Plane's new W250i planers fitted with hydraulically powered offset laser levelling allowed the machines to use the same reference point for levels where there was no deformation. The work was completed to the clients satisfaction on time without delays or damage to the bridge.
