Surface Preparation.

Effective surface preparation is critical to the performance and longevity of concrete repairs, strengthening systems and protective treatments. Direct Inject provides specialist high and ultra-high-pressure water jetting solutions for surface preparation and cleaning across new construction, remediation and maintenance works, with methods selected to suit the condition of the existing substrate and requirements of the subsequent system.

Surface Preparation.

Direct Inject provides high-pressure water jetting and hydro-scarification for the controlled preparation of concrete surfaces. The process selectively removes laitance, weak or deteriorated concrete, existing coatings and surface contaminants without introducing impact or vibration into the structure, leaving a clean, textured and mechanically sound substrate ready for concrete repairs, strengthening systems, construction joints and protective coatings.

Services
  1. Hand Lancing – High-pressure water jetting using hand-held lances for smaller works, restricted-access areas and rapid mobilisation. Provides flexibility around complex details, edges and penetrations where automated equipment cannot operate effectively.
  2. Hydro Mower – Mechanised surface preparation for slabs, decks and other large horizontal concrete surfaces. Provides consistent cleaning, scarification and removal of the upper concrete surface to achieve a uniform prepared profile.
  3. Track-Mounted Robots – Robotic hydro-scarification for large-scale surface preparation requiring productivity and consistent material removal. Systems traverse concrete surfaces at controlled pressure, stand-off and travel speeds to achieve the required profile.
  4. Rail-Guided Robots – Rail-mounted systems for vertical, overhead and complex surfaces where track-mounted equipment cannot operate. Modular rails provide controlled positioning of the cutting head for consistent preparation across difficult geometries.

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.”

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.”
