GCI personnel rappel down the exterior of a 150' tall steel stack to obtain "UT" measurements of the steel shell.

Gibraltar Chimney International offers a full compliment of inspection services. We are active contributing members of the ASCE (American Society of Civil Engineers), Fossil Power Committee on Chimney and Stack Assessment and our personnel have been instrumental in formulating numerous Chimney and Stack Inspection Programs for utility companies throughout the United States.

We recognize that planned maintenance is considerably more cost effective than unscheduled maintenance and therefore we concentrate on providing our clients with detailed and comprehensive inspections that will assist them in developing a planned maintenance approach to their chimney/stack maintenance.

Our efforts and commitment to provide professional inspection services for chimneys and stacks begins with our experience and knowledge, obtained through both field experience and study. Combining this experience with a thorough understanding of various NDT methods, inspection technologies and code requirements enables GCI to offer a vast array of inspection services.
