Project: Home Depot Garden Center New Construction
Problem: Shrinkage cracks appeared before control joints could be cut. Solution: Roadware 10 Minute Concrete Mender™ topped with Ardex CD Concrete Dressing |
|||
 |
The Garden Center developed shrinkage cracks parallel to the control joints ranging from hairline to 1/4" wide. | |||
 |
The crack are lightly scored and cleaned out with a diamond blade attached to an electric grinder. Dust and debris is removed with a vacuum. | |||
 |
Ultra penetrating Roadware 10 Minute Concrete Mender™ is applied directly the crack followed by a 1/4" layer of 40/30 grit silica sand. | |||
 |
Repairs are made full depth. Silica sand is added to stop "sinkers" and build a polymer concrete matrix. | |||
 |
Additional material and sand is added to fill the crack up to the top. | |||
 |
Excess material is trowelled or scraped of before curing. | |||
 |
After 10 minutes at 70° F., the repair is ready for traffic or finishing if desired. Here a concrete finishing stone is used to blend the repair with the surrounding concrete. | |||
 |
A brushed on topping of Roadware MenderBlender™ or Concrete Dressing is added to completely blend the repair into the concrete. | |||
 |
After the MenderBlender™ cures for an hour, the crack is repaired structurally, and is nearly invisible. | |||
