Downer Group – Hume By-pass Wodonga, Vic
Downer Group works in alliance (NEMA) with VicRoads to maintain regional road infrastructure in North East Victoria.
Engineers, GHD advised Downer Group that ITL solutions could be utilised in some civil engineering applications such as slope protection, drainage control, outfalls and culverts.
An example shown is at Wodonga on the Vic/NSW border, where the Albury/Wodonga Hume By-pass crosses over the old Hume Highway.
Beeching is a rock layer used to stabilise an embankment. Over time these rocks have dislodged or been removed allowing water ingress.
Rather than replacing the rocks a more cost effective and efficient solution was to cap the rocks with ITL Aqualiner, attach it to the surrounding bridge walls, install a surface gutter and downpipe to remove surface water.
The joins have been sprayed with ITL Aquaseal.
