Concrete Demolition Made Easy!

Our Remotely Controlled Concrete Hydrodemolition Systems Minimise risk to yourself and others on-site, delivering a safe, cost effective, vibration free method to Remove Reinforced Concrete on Bridge Decks, Road Surfaces, Runways, Dam Walls, Tunnels, Docks, Harbours, Multi-Storey Car Parking Decks... and More!

Gnat's State of the Art Aquajet and NALTA Hydrodemolition Robots harness Ultra High-Pressure Water Jets to Effortlessly Demolish and Remove Concrete Substrates and Reinforced Concrete Structures. Much quieter in operation than traditional heavy-duty percussive equipment, Hydrodemolition Minimises Acoustic Impact on-site and Surrounding material suffers no cracking. Reinforcing steel within the concrete core can be retained undamaged and ready to receive new Reinforcement Bars and Concrete as required.
