Please name five methods of concrete crack repair.
Here are eight possible methods of repair:
For active cracks:
1. Routing and sealing
2. Polyurethane injection
For dormant cracks, the methods above plus:
3. Epoxy injection
4. Stitching and doweling
5. Gravity filling
6. Dry packing
7. Overlays and surface treatments
8. Autogenous healing
And, finally, often an acceptable course of action is no repair at all.
