Time. It takes its toll everywhere. Buildings are no exception. Facilities in 24-hour use are particularly susceptible.
Material cracks or discoloration bring our structural engineers into the field for evaluation and problem assessment. Suspected seepage sends our non-destructive testing (NDT) teams out to do infrared inspections. Surface peeling signals our petrographers to conduct core studies. Ambient vibration causes unique problems that we monitor and analyze, and for which we engineer solutions. CTLGroup maintenance plans and service-life projections keep our buildings and facilities clients in business.
