PROJECT STATS:

  • 1656 square metres
  • 46 x 15m rolls of Concrete Erosion Mat (uncracked)
  • 20 tonne excavator
  • 1 operator and 2 labourers
  • Client request – Uncracked concrete over Geogrid, makes rolls less flexible, less vegetation growth through the mat and heavier to handle.

PROJECT OVERVIEW

Contractors, Davbridge Construction installed the flexible concrete erosion mats for Ipswich Shire Council on the new Deebing Creek Bridge project at Ripley QLD. The bridge abutments were lined with concrete erosion mats to stabilise the slopes and control erosion and runoff.
