Hydro-demolition.

Whether facilitating repairs, accommodating new construction, modifying existing assets or supporting end-of-life decommissioning, controlled concrete removal requires precision and planning. Direct Inject combines robotic hydro-demolition, ultra-high-pressure water jetting and specialist cutting techniques to remove concrete safely while protecting surrounding structures and maintaining operational continuity wherever possible.

Non-Structural Hydro-Demolition.

For non-structural applications, Direct Inject uses hydro-demolition to selectively remove concrete to defined depths, profiles and boundaries while preserving existing reinforcement and minimising vibration and damage to the retained structure. Works are completed using hand lances, track-mounted robots and rail-guided robotic systems, with equipment and methodology selected to suit the removal volume, geometry, access constraints and requirements of each application.

Services
  1. Controlled & Targeted Concrete Removal – Selective removal of defective or nominated concrete while preserving reinforcement and surrounding sound concrete. Applications include steel augmentation, new connections, stitch pours and removal of non-compliant concrete prior to rebuilding.
  2. Circular Pile Trimming – Robotic removal of excess concrete from piles to expose reinforcement for pile cap connections. Our Aquajet 750 circular system accommodates pile diameters from approximately 900–1,500 mm and can operate at heights up to 6 m.
  3. Diaphragm Wall Trimming – Controlled removal of excess concrete from diaphragm walls to nominated lines, levels and profiles. Works can be completed using hand lances, track-mounted robots or rail-guided systems to suit access, geometry and removal requirements.
  4. Water Treatment & Recycling – Mobile treatment systems capable of processing 20–80 m³/hr, neutralising pH with CO₂ and removing TSS down to 1 micron. Treated water can be returned to the hydro-demolition process, reducing water demand and off-site disposal

Structural Hydro-demolition.

Direct Inject provides specialist hydro-demolition equipment, operators and technical capability for the controlled removal of structural concrete as part of major infrastructure upgrades, modifications and asset decommissioning. Where works involve the demolition or removal of load-bearing structural elements, we work alongside trusted and appropriately licensed demolition contractors to provide an integrated delivery solution. Hydro-demolition allows concrete to be selectively removed while preserving nominated reinforcement and adjacent structural elements where required by the demolition design and methodology.

Services
  1. Structural Removal & Modification – Controlled removal of structural concrete to support major modifications or asset expansion. Robotic and rail-guided systems enable selective removal while preserving nominated reinforcement and adjacent structural elements.
  2. Asset Decommissioning – Selective hydro-demolition during the dismantling or decommissioning of reinforced concrete infrastructure. Applications include reinforcement exposure, concrete removal and separation of structural elements ahead of subsequent demolition works.
  3. Licensed Demolition Partnerships – Structural hydro-demolition is delivered with appropriately licensed demolition contractors where required. Direct Inject provides the specialist equipment, operators and hydro-demolition expertise within the engineered demolition methodology.
  4. Water Treatment & Recycling – Mobile treatment systems capable of processing 20–80 m³/hr, neutralising pH with CO₂ and treating suspended solids down to 1 micron. Treated water can be returned to the hydro-demolition process, reducing water demand and off-site disposal.

CPB
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.”

Area Manager – CPB Contractors, 2024

John Holland
John Holland Project
“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”

Project Manager – John Holland, 2025

JAGCON
JAGCON Project
“JAGCON Group directly assisted the head contractor CPB Contractors & Ghella Joint Venture by seconding engineering and project management personnel directly into the JV team including myself in the capacity of Construction Manager………… What really set Direct Inject apart was their flexibility. When we needed them to scale up their workforce at short notice during critical construction phases, they made it happen. Equally importantly, they could scale down when required without complications.”
