Concrete Repair
eCPR refers to a series of repair techniques used to bring the structural capacity or rideability of a deteriorating concrete pavement to an acceptable condition. CPR techniques each have a unique purpose to repair or replace a particular distress (kind of deterioration) found in concrete pavement, or to prevent or slow further deterioration. The seven most common CPR techniques are:
- Slab stabilization
- Full-depth repair
- Partial-depth repair
- Retrofitting dowels
- Cross-stitching longitudinally-oriented cracks or longitudinal joints
- Diamond grinding
- Joint & crack resealing
Learn more about each technique at at the International Grooving & Grinding website.
