Contractors and site managers must comply with vibration control procedures to avoid damage to nearby structures during a construction project. Site managers will ensure vibration monitoring tools are both implemented and functional, and pre/ post construction crack inspections may be performed. The abrasion resistance of concrete surfaces is normally improved by adequate compaction. However, excessive vibration, or excessive working of the surface, can cause an excessive amount of mortar (and moisture) to collect at the surface, thereby reducing its potential abrasion resistance. Vibration of fresh concrete reduces its internal shear strength, and enables concrete to momentarily liquefy to facilitate the consolidation process. When the vibration stops, the liquid flow subsides.
