What happens here

The expert then explains 'expansion joints.' Unlike saw cuts, expansion joints are specifically designed to accommodate movement. Examples provided include cold joints (where two concrete pours meet), areas around structural beams that may move independently, or where a stem wall meets the floor slab. These areas require joints that can flex and expand/contract, implying that a flexible filler is necessary if they are to be addressed.

Goal: Understand the purpose and placement of expansion joints.

while the concrete is wet uh in order to control the cracking. An expansion joint is usually uh placed with a thought process in mind of movement. So, maybe that looks like a coal joint. Maybe that's a structural beam uh that has needs that expansion. Maybe that's where the stem wall meets the floor. That's really more of an expansion joint. Uh we're kind of using the phrase just as a general there, but a true control joint
