In the context of Australian commercial construction projects, "scabble" refers to a specific surface preparation technique. Scabbling is a process used to roughen or shape concrete surfaces. This is typically done to prepare the surface for additional treatments, coatings, or to ensure better adhesion of new concrete or other materials. The process involves using a scabbling machine or hand tools to chip away at the concrete surface, creating a rough texture. This technique is often employed to remove laitance, level uneven surfaces, or expose aggregate for aesthetic or functional purposes.

The purpose of scabble is to increase the surface area and improve the bond between the existing material and the new construction materials, such as concrete, mortar, or other adhesives. This process helps to ensure a strong and durable bond, which is essential for the structural integrity and longevity of the construction project.

Scabble is commonly used in various construction applications, such as repairing and strengthening existing concrete structures, installing new concrete overlays or toppings, and bonding new construction materials to existing surfaces. It is a widely accepted and recognized technique in the Australian construction industry and is often specified in project plans and specifications.
