This includes:

• Ultrasonic thickness measurement of steel.
• Half-cell chloride potential for risk of corrosion in concrete.
• Acid-soluble chloride content measurement to determine the extent of chloride penetration at the reinforcing steel.
• Petrographic and mechanical analysis including compressive strength. 
• Modulus of elasticity and splitting tensile strength.

OCC frequently uses hydraulic core drilling equipment to extract samples from concrete structures.
