Impact of Cleanliness and Rebar on Foundation Strength

What happens here

The video provides a stark visual comparison between a foundation built without proper preparation (dirty surface, no rebar) and one built with rebar. A wall constructed on a dirty surface or without rebar is shown to fail easily under minimal lateral pressure. In contrast, a wall with rebar, properly integrated, resists significant force, highlighting rebar's ability to 'pin' the block courses to the footing, creating a unified and strong structure.

Goal: Understand how a clean foundation surface and rebar contribute to overall strength.
