Imperial Towers Underpinning

Imperial Towers was affected by sinkhole activity and experienced settlement and cracking. McCrossin Foundations installed four underpinning elements to support the building’s southwest corner.  These elements each consisted of two micropiles – one acting in compression, one in tension – and a double c-channel needle beam spanning the micropiles and cantilevering under the existing footing.  McCrossin Foundations self-performed the micropile and beam installation, which included drilling and grouting the micropiles in difficult karst terrain, cutting the piles to the proper elevation, and installing the pre-fabricated needle beams.

“McCrossin Foundations performed their duties in a very professional manner. They arrived to the site each day on time. They explained to our maintenance personnel what would be needed for the day, stated their time to do it and completed the work on time. If they ran into something they were not expecting they quickly told the staff what it was, how it would be fixed and moved forward to complete the work. Their professionalism went a long way towards the completion of the project. We were quite pleased with their performance.”
