Vibrate/Tap Formwork for Smooth Edges

What happens here

After placing concrete, tap or vibrate the formwork. Use a hammer to gently tap along the exterior of the forms. This action helps to release any trapped air pockets, consolidates the concrete against the forms, and brings cement paste to the surface, resulting in smooth and strong edges. If the forms are not vibrated or tapped, the edges of the concrete will likely be rough and crumbly.

Goal: Achieve smooth, dense, and well-formed concrete edges by vibrating the formwork.
