Covermeter is used for locating reinforcement in the concrete.  Then a suitable coring location shall be selected in order to prevent the damage of the casted reinforcement.  In general the core shall be drilled perpendicular to the surface using a diamond core drilling bit.  Immediately after drilling, the core shall be sampled and marked up with its location and orientation within the member.

Coring Equipements and Procedures:
Covermeter was used to locate reinforcement in concrete before coring	Coring a sample from beam	Cored hole on the beam	Mounting the coring machine on the column
Coring the sample from column	Controlling the coring speed	Coring a slab sample	Chisel out the sample
The core sample from slab	Marking the sample with sampling data and location	Filled the cored hole with equivalent concrete strength non-shinkage grout
