Underwater Hydrodemolition

What Is Underwater Hydrodemolition Service

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.

Benefits of Underwater Hydrodemolition

Precise Structural Protection

Underwater Hydrodemolition removes damaged concrete while leaving the internal steel reinforcement intact, ensuring repairs can be carried out safely without compromising structural integrity.

Suitable for a Wide Range of Marine Structures

This method can be applied to numerous offshore assets, including jetties, piers, quaysides, docks, mooring dolphins and breakwaters, making it highly versatile for marine infrastructure projects.

Enhanced Diver Safety and Comfort

Specialist Zero Thrust diving guns balance force at both ends of the tool, significantly reducing strain on the diver and allowing them to work more safely and for longer periods underwater.

Stable and Controlled Underwater Operation

Durable frames such as the Aqua Spine system enable secure positioning and controlled demolition, ensuring accurate, consistent results even in challenging underwater environments.

Safe and Precise Underwater Hydrodemolition

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.
