What happens here

Once the concrete has set enough to pass the 'finger test' (your finger indents slightly but leaves a clean mark), it's time to cut the control joints. Use a joint cutter and a straight edge to create precise, straight lines. Control joints are designed to create weakened planes in the concrete, encouraging any cracking to occur along these lines rather than randomly across the surface.

Goal: Create weakened planes to manage concrete cracking

Tools and materials

  • Joint Cutter — Creating control joints in concrete
  • Straight Edge — Guiding the joint cutter for straight lines

What they say

that's been pretty loose Ryan if that's the way you wanted it yeah so all the concrete's been down for about 15 minutes and Juan's gonna start to put in the control droids these are designed to keep the concrete from cracking and what that means is if your concrete starts to crack this control joint should stop it from cracking all the way through
