Which of the following processes occurs last in finishing concrete slabs?

In finishing concrete slabs, the last process typically consists of broom finishing. This technique helps to create a textured surface on the concrete, enhancing its slip resistance, which is particularly important for outdoor surfaces exposed to moisture or other potentially slippery conditions. By using a broom, a desirable profile is imparted to the concrete, providing both functional and aesthetic value.

Broom finishing follows other essential finishing processes such as troweling, edging, and jointing. Troweling smooths the surface, edging reinforces the edges of the slab and helps prevent cracking, and jointing creates intentional cracks to control where the concrete will break as it expands and contracts. However, these processes happen prior to broom finishing to ensure that the surface is adequately prepared and refined before the texture is added for safety and aesthetic purposes.
