Using a variety of expert equipment, we are able to remove unwanted concrete beneath the surface of the water.
Depending on the nature of the job, Hydroblast will either supply specialist diving guns (for both the UK and overseas) or employ a diving company, working collaboratively towards quick and safe Hydrodemolition Underwater.






Underwater Hydrodemolition offers a controlled and reliable way to remove damaged concrete below the waterline, using specialist high-pressure equipment to remove concrete accurately without affecting the internal steel reinforcement.
Our underwater systems are purpose-built for marine environments, with durable frames like the Aqua Spine and stainless-steel Zero Thrust diving guns allowing divers to work with improved stability and accuracy across structures such as jetties, piers, docks and mooring dolphins.
Safety remains the priority throughout the process, with Zero Thrust technology reducing recoil and strain on the diver, improving control and making underwater demolition more manageable and efficient.
