D-Drill contracted to demolish M4 bridge wing walls
August 29th 2008

Diamond drilling, sawing and demolition specialist, D-Drill recently completed a contract for the M4 motorway widening project at Cardiff Gate. Contracted by project leaders Carillion, D-Drill was brought in to cut the abutments at Rhymney and Rhydry bridges to accommodate a third lane.

These bridges are part of an expansion project to ease traffic congestion at peak times. D-Drill cut bridge abutments of 470mm and 600mm thicknesses using wall saws, allowing the structure underneath the bridge to be widened in order to hold the extra lane above.

Julie White, D-Drill’s managing director commented, “This was a relatively short but important project for us. It took under 2 weeks to complete work on the first, eastbound, carriageway. The main emphasis was to ensure minimal disruption to the surrounding roads and local traffic; this was achieved by using a well trained crew and state of the art equipment.”

Julie continued, “Some areas had restricted access and needed careful planning. Due to the nature of the contract there was very little space to operate the wire saw. D-Drill modified the rig especially for this job. D-Drill’s vast experience in this field was an obvious advantage.
