Introduction A cold joint rescue is blending a second-day concrete pour to erase the seam and create one continuous surface. If you can see a raised line, a color change, or a rough edge where the old pour meets new concrete, that’s a cold joint. The goal is to make the transition look and act

Take time to prep the area,

Introduction Repairing broken control joints means fixing the gap between concrete slabs so movement and moisture are controlled.
