Hidden Valley Builders (installed CELBLOX) for the Flaherty Primary Center, a 67,473 square foot school located in Ekron, Kentucky.
The project included 12” ICF gymnasium walls that were 38’ high. This portion of the project was poured in two separate lifts of approximately 20 feet. While generally HVB utilizes a ¾” or one inch diameter vibrator to consolidate the poured concrete within the ICF wall, for these walls we were required to us a 2” diameter vibrator. Considering the diameter and the vibratory force of this larger instrument, the CELBLOX ICF’s performed exceptionally well without any structural issues due to the pour or the vibratory compaction process. Typically the corners are the most vulnerable during an ICF pour. The CELBLOX corners experienced no problems whatsoever, without any extra strapping or bracing beyond what is recommended by the manufacturer.
CELBLOX ICF’s were very fast to work with. The tongue and groove design locked tightly together making the wall easy to straighten and plumb prior to the pour. It was also quick and easy to kep clean of any debris.
Compared to other ICF’s being used for commercial buildings, CELBLOX ICF;s used on this project have received favorable comments. Kenny Stanfield from project designer Sherman Carter Barnhart Architects commented that Flaherty was the best ICF school he’s seen yet when he came out to view the jobsite in September.
