Hydrodemolition or "Hydroblasting" is a concrete removal technique which utilises ultra-high-pressure water to remove unwanted concrete, asphalt, and grout. This process provides an excellent bonding surface for repair material and new coating applications.
At RGL we specialise on “taking the man away from the job” and have a selection of semi-automatic, hydraulically driven equipment which can be remotely operated. There is always a need for some “hand gunning” works but we try to keep this top a minimum in favour of our remotely operated options.
The method is widely used in the alteration or repair of structures in many industry sectors. It is recognised by many civil engineers, structural engineers and consultants as the safest, most effective, vibration-free method of removing concrete.
RGL have pioneered the introduction of “Ultra High Pressure” water jetting into the hydrodemolition industry and continue to build on our solid reputation that has been developed over the past 35 years.
In some instances, you may only wish to remove a small area of concrete or conduct Hydroarchaeology where avoiding underlying surfaces and brick work is paramount. Whether you require the cut to be a certain shape or need to protect the surrounding surfaces from damage, UHP water jetting and RGL can offer the perfect solution.
Where robotic Hydrodemolition isn’t practical, selective concrete removal with a hand lance is a very effective alternative.
Our skilled operators can cut very accurately by hand with the added advantage of being able to get to hard to reach areas where it would be impossible or impractical to deploy our robot technology.
Where possible, we would always favour the use of Robotic Hydrodemolition, they are excellent where large areas of concrete need to be removed.
Our robots save time and improve safety by eliminating the labour-intensive use of hand tools and offer faster concrete removal. They keep the operator at a safe distance from the working face and avoid causing micro fractures associated with traditional methods.
