Robotic Hydrodemolition

A safe, cost-effective system for Bulk Concrete Demolition

Hydrodemolition utilises Ultra High-Pressure Water Jets to cut effortlessly through Reinforced Concrete.  Our Remotely Controlled Hydrodemolition Systems minimise risk to yourself and others on-site and provide 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 deliver a number of Advantages, compared to traditional methods:

  • They are quieter in operation than traditional heavy-duty percussive equipment

  • Acoustic Impact is much reduced on-site

  • Surrounding material suffers no cracking.

  • Reinforcing steel within the concrete core can be retained undamaged and ready to receive new Reinforcement Bars and Concrete

Gnat UK's Aquajet and Conjet Hydrodemolition Hire Fleet

Specially designed for operations in confined areas, our Hydrodemolition Robots are both versatile and manoeuvrable - their heads can operate horizontally, vertically and in over-head situations, allowing for safe operation and efficient, cost-effective demolition in confined areas without limitation

When fitted with its boom arm extension kit, its operational reach is extended in both vertical and under/up operations. This enables the cutter robot to work directly from the bridge deck to reach the Sides and Underneath a bridge without dismounting the bridge railing/parapet

ERGO and NALTA Hydrodemolition Systems - A Safer Alternative to Hand Lancing

Our Hydrodemolition Procedures also utilise ERGO and NALTA SYSTEMS. These are designed to Replace Hand Lancing for a large number of Hydrodemolition Applications. These innovative Systems enable Increased Productivity and vastly Improved Operator Safety
