Concrete Scabbling: Preparing Surfaces for Long-Lasting Repairs
In construction and civil engineering, achieving durable repairs starts with proper surface preparation. Traditional scabbling methods using pneumatic tools generate dust, vibration, and health risks like Hand-Arm Vibration Syndrome (HAVS). RGL Services' ultra-high-pressure (UHP) water scabbling offers a safer, dust-free alternative, roughening concrete for superior coating adhesion and overlays.
How UHP Water Scabbling Works
UHP water jets at over 1,500 bar erode the top concrete layer, creating a textured profile roughness for optimal bonding. Robotic or handheld lances ensure precision, removing laitance, levelling surfaces and creating non-slip finishes. The process is contained, with water recycled on-site for minimal environmental impact.

Key Benefits
- Enhanced Adhesion: Textured surfaces provide mechanical interlock, boosting coating and screed bonds by up to 30% for longer-lasting repairs.
- Worker Safety: No vibration or dust reduces HAVS and respiratory risks, ideal for confined spaces.
- Versatility: Suitable for floors, walls, bridges, and marine structures; exposes aggregates for aesthetics.
- Efficiency: Faster than mechanical methods, with less downtime and cleanup.
