Hydrodemolition of Concrete

Hydrodemolition is a concrete removal technique which uses the technique of using high pressure or ultra high pressure water jets to cut and remove concrete from a structure. 

The principal benefit is that the water jetting process leaves steel reinforcement and/or structural embedments undamaged and ready for re-use. The method is widely used in the alteration or repair of structures in many industry sectors. It is recognised by civil engineers, structural engineers and consultants as the safest, most effective, vibration-free method of removing concrete. 

RGL are the leading hydrodemolition contractors, operating across the UK for over 35 years.

• Removal of new concrete that has been placed in the wrong place, has not reached the correct strength or was poured without the steel reinforcement in place
• Removal of existing concrete to allow tying into existing structures e.g. concrete pockets can be accurately cut
• Preserve expensive steel fabrication
• Removing concrete in close proximity to water/gas mains and high voltage cables
• Concrete damaged by salt and other chemicals
• Under water removal of concrete
• Removal of coatings, laitance, waterproofing, aggregate exposure, spalling or damaged concrete
• Concrete surface preparation for bonding with new concrete (known as concrete scabbling)
• Preparation and protection of steel structures
• Pipe Blockages 

• No HAVS issues – crews can work normal hours without risk
• No heat/dust, sparks created or blades to clog or go blunt
• Usually faster than jack hammering
• Noise caused created by percussive tools is eliminated
