The SR-114 Geneva Road is a Spiralnail project constructed in 2012 by the Slaton Bros.  This project consists of 20 hot dipped galvanized Spiralnails ranging from 16'-26' for supplemental load requirements for each concrete precast panel, range from 4-21.3 Kips.

After installation of an MSE precast wall system, a potential structural problem compromised the safety factor.  As a pre-emptive measure to restore the safety factor, Hilfiker supplied Spiralnails that were installed through the face of the panels to mitigate the problem and provide supplementary reinforcement. 

Lot 121 Deer Crest-Pichinson Residence is a Welded Wire Wall / Spiralnail project. The Lot 121 Deer Crest-Pichinson Residence project was bulilt in 2008 and consists of 2200 SF of Welded Wire Wall, and 96 Spiralnails. 

This project was to add on to an existing wall that was installed about 10 years prior.  The 10 year old wall needed and additional 20' of Welded Wire Wall on top of the existing wall. The wall is now a tiered with a height of 46'.  For additional reinforcement, Spiralnails were installed in the existing wall to account for the load of the new wall on top.
