What is the process of rounding off the formed edge of a slab to prevent chipping or damage called?

The process of rounding off the formed edge of a slab to prevent chipping or damage is referred to as edging. Edging typically involves creating a smooth, rounded profile along the edges of concrete slabs to enhance their durability and aesthetic appeal. By softening the edges, this technique reduces the likelihood of chipping or cracking that can occur in sharper corners during handling or over time due to environmental factors.

In many construction scenarios, particularly in the finishing phases, edging is crucial for ensuring the longevity of the concrete surface. It is often done after the initial setting of the concrete and can significantly improve the overall resilience of the slab.

The other options relate to different aspects of concrete finishing. Jointing refers to the incorporation of intentional grooves in a concrete slab to control cracking. Floating involves using a float tool to achieve a flat and level surface. Troweling is the action of smoothing the surface with a trowel to create a fine finish. Each of these processes plays a vital role in working with concrete, but they differ in purpose and execution from edging.
