Hydrodemolition Services
Whether it’s scabbling, cutting, selective or full concrete removal – Kelly’s can do it all.

Scabbling is a technique used to roughen up surfaces or reduce concrete levels by removing a thin layer from the top. Water jet scabbling is an environmentally friendly and cost-effective method for removing the surface of concrete to create a surface profile. Scabbling can be used to prepare areas for repair, create more grip by roughing up surfaces, decorative effects and much more.

Cutting: With the right combination of pressure and volume, plus the expertise of experienced operators, Kelly’s are able to make precision cuts in concrete in areas where other methods are not viable. Dam walls, expansion joints and inside pipes are just a few examples of where this service has been performed.

Demolition: Hydrodemolition is used to remove areas of loose, deteriorated and damaged concrete from structures such as wharfs, bridges and chimneys. Hydrodemolition offers a number of advantages, such as:

  • Vibration free – no microfractures
  • Produces excellent bonding surface for repair material
  • Removes contaminants such as chlorides
  • Removes corrosion from reinforcing without damage
  • Increase production rate
  • Enhanced safety – remote operation available
