Condition Assessment and Repair Recommendation for 100+ Year Old Hall of Records in Bakersfield, CA.

Concrete Science, Inc. performed following tests to determine the cause and extent of reinforcement corrosion and provide repair options:

1. The beams and columns were scanned for reinforcement and then core d to expose the reinforcement. The exposed reinforcement was used to conduct half - cell electrical corrosion potential test to determine the degree of reinforcement corrosion

2. Powder sample from concrete beams, columns, footings, and walls were obtained for chemical analysis to determine chloride content concrete

3. Soil samples were obtained from locations adjacent to the columns and footings for determining, chlorides, sulfates, resistivity, and pH

4. Performed nondestructive Schmidt Hammer Testing on various columns, beams, walls, and elevated slab to estimate concrete compressive strength
