Barriers and walls

Concrete barriers improve traffic safety on roads, effective in withstanding median cross-overs & other potentially serious motor accidents. The strength & durability of concrete barriers and walls allows substantial forces to be sustained.


Concrete pavements are now one of the best investments available to all government and council authorities. Long life, low maintenance, proven safety and the good riding quality obtainable are all major benefits.

Drains & Canals

A wide selection of drains and canals has been constructed by Dowsing NSW including Box Drains, Canal, Conduit Drains, V-Drains, Variable Width and Water Channels. Concrete can be easily shaped and formed with many colours available.

Diamond Grinding

Diamond Grinding is a cost effective and alternative method to restore deteriorated and out of specification concrete or asphalt pavement surfaces. It involves the removal of a layer of hardened concrete using diamond blades.
