Palmetto Gunite Construction Company is currently involved in a seismic retrofit project of an existing research facility near Charleston, SC. Micropiles are being installed vertically and at a 45 degree angle. Pile caps are being constructed around these piles to act as stiffeners in the event of seismic loadings. Existing footings have been retrofitted, and new grade beams are being created between existing pile caps under the research facility.

Shotcrete Research at Laval University

Palmetto Gunite Construction Company aided two graduate students in their master’s and doctoral, shotcrete research which was performed at Laval University in Quebec City, Quebec. Will and Robert Snow were sent, along with local, donated materials, to perform the research in Laval’s Civil Engineering laboratories. Dry mix test panels were shot wit the donated materials. Will Snow provided his experience as an A.C.I. Certified Nozzleman to aid in the shooting of shotcrete panels. Test panels were shot at a constant air flow from different distances in order to determine how possible changes in methods could affect the quality of the shotcrete. The different combinations were also subjected to rebound tests to determine how the distance and air flow can change the amount of material, as well as the size of the aggregate, that ultimately forms the in-place shotcrete.

After a structural analysis of the existing soccer scoreboard foundation in preparation for a new, larger scoreboard, it was determined that 2 additional piles are required to provide overturning resistance needed for the anticipated wind loads.

Palmetto Gunite Construction Co., Inc. installs (2) 70' deep Titan 52/26 micropiles within 5' of the existing scoreboard foundation, causing no vibration or damage to the existing structure.

Installed micro piles with top connection installed. The new grade beam will be installed and tied to the existing foundation before placement of the new scoreboard.
