CPB Project
“I worked with Direct Inject throughout the entire delivery phase of the Western Sydney Airport SBT project. Their team played a significant role in the project achieving most of its critical portion handovers and their willingness to really become an extension of our engineering team rather than just a labour hire contractor was refreshing.”

“I have utilised Direct Inject on two Major Projects in Sydney and in different capacities. Firstly, PU Injection and secondly robotic hydro demolition. What impresses me the most is their no fuss attitude and commitment to getting the right outcome for their Client. In both instances they have delivered and exceeded on what has been expected. I’ll certainly be engaging their services again”
