Surface Preparation / Concrete Bond Face Preparation
Surface preparation ranges from surface cleaning and removal of detritus to varying degrees of aggregate exposure.
Advantages over percussive methods include:
Eliminates the exposure to hand-arm vibration.- No microcracking within the structure caused by percussive methods. This can lead to shattered surface aggregate.
- Promotes enhanced bond.
- No dust created.
- Better working environment for operatives.
- Removes surface contaminants.
Utilising fan jets, or single/multiple spinning jet attached to handheld or robotic equipment.
Pressures, flow rates and nozzle configuration can be adjusted to achieve the required finish.
