Why hire Gnat UK's AQUAJET & ERGO Hydrodemolition Robots?
Gnat UK's Aquajet Hydrodemolition Robots offers distinct advantages over traditional concrete removal methods:
Our Aquajet Hydrodemolition Robots are specially designed for operations in confined areas and are purpose built to safely and accurately deconstruct reinforced concrete. They are powerful, 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
Access All Areas!
When fitted with its boom arm extension, operational reach is extended in vertical and under/up operations. This enables the cutter robot to work directly from motorway/railway bridge decks to reach the Sides and Underneath directly from the bridge deck

Hydrodemolition utilises Ultra High-Pressure Water Jets to cut effortlessly through Reinforced Concrete. The System minimises risk to yourself and others on-site and provides 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 ERGO Hydrodemolition Systems deliver several 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.
