Hydro-demolition is a concrete removal technique which utilises high pressure water to remove deteriorated or sound concrete. Chemcem use this technique to repair and maintain structures together with high pressure water equipment for the removal of old waterproofing systems. Chemcem has a team of trained hydro-demolition operatives approved by The WJA providing specialist services in:
- Manual hand lance hydro-demolition
- Semi-automatic mini digger mounted hydro-cannons
- Fully robotic systems
Our range of specialist hydro-demolition techniques significantly increases the rate of concrete removal within a safer working environment. This process eliminates the risk of micro-cracking in the concrete, maintains the integrity of reinforcement and avoids any hand vibration issues normally experienced with hand held pneumatic equipment. This process can be further supported with Chemcem’s own Siltbusters and PH Adjusters for treatment of waste water.
Chemcem is USL’s approved applicators in Scotland of their HAPAS approved Britdex Bridge Deck Waterproofing Systems. Our team also provide a variety of waterproofing and anti-skid coatings for walkway surfaces.
Chemcem provide cathodic protection through embedded galvanic anodes for concrete structures. Methods employed include for both tied installation to rebar within localised patch repairs and cored installation complete with continuity wire connection.
