Rebar Placement for Reinforcement

What happens here

Short pieces of rebar (pink-coated for visibility) are bent and placed within the formwork to provide structural reinforcement for the concrete slab. These are laid in a grid pattern and secured with wire ties where they cross. The presenter notes that these are not strictly necessary for this small slab but add extra strength. The rebar is raised slightly off the plywood base using small concrete pucks (chairs) or similar spacers to ensure it is embedded within the concrete.

Goal: Provide structural integrity to the concrete slab with rebar reinforcement.
