Direct Inject use track-mounted robots for large-scale concrete removal and surface preparation on slabs, walls, and overhead structures.
Our AquaJet 750Vs are the largest hydro-demolition robots available. Their size and power produce unmatched productivity whilst their state-of the art guidance system allow concrete removal to be controlled with a level of precision that no other machine can provide.
Complementing the 750Vs, is our Brokk 200 with an ultra-high pressure lance. This machine offers five directions of articulation, giving us exceptional flexibility in accessing complex areas while maintaining consistent removal performance. Together, these machines allow us to complete major works quickly, safely, and to the highest standard.
Large-scale partial or full-depth removal of concrete slabs, bridge decks, and floor structures.
Overhead concrete removal in tunnels, culverts, and under bridges.
Precision trimming of piles, diaphragm walls, and structural elements.
Surface preparation for new overlays, waterproofing membranes, or protective coatings.
Stripping defective or deteriorated linings from steel and concrete tanks
Our AquaJet Ergo-Go units, paired with custom scaffold-mounted guiderails, make it possible to remove concrete or prepare surfaces in areas with restricted access and complex geometries. These rail-climbing systems deliver the same precision and quality as our larger robots, but are purpose-built for confined spaces, curved structures, and locations traditional equipment can’t reach
Concrete removal in reservoirs, tanks, and silos with curved or vertical walls.
Surface preparation on structures with complex geometries or limited access.
Hydro-demolition in confined spaces where conventional track-mounted robots cannot operate.
Targeted removal on tall or steep surfaces using scaffold-mounted guiderail systems.
Preparation of surfaces for coatings, overlays, or repairs in sensitive or hard-to-reach environment
For areas that robots can’t reach or where the scope is smaller, our hand-lancing crews mobilise quickly with trailer-mounted UHP pumps. This setup allows for targeted demolition, surface preparation, and the removal of existing coatings or linings in tight spaces or on irregular surfaces. Hand lancing maintains the same dust-free, controlled process as our robotic systems while offering maximum flexibility on site
Small-scale concrete removal in areas with unusual geometry or severe access restrictions.
Localised surface preparation for patch repairs, joint work, or tie-ins.
Stripping existing coatings or linings from tanks, bunds, or other structures.
Edge detailing or precision removal around embedded fixtures and fittings.
Out-of-hours or rapid-response works where fast mobilisation is essential.
