ICC (ESR-4238) approved precast concrete Perma-Column® that are an alternative to preservative treated wood thus ensuring the structural integrity of your building’s foundation, a simple and efficient construction method that has the durability of a concrete foundation. No Mess. No Cure Time.
Concrete Column - Self Consolidating Concrete (SCC) precasting technology that includes microfibers, superplasticizers, microsilicia, a corrosion inhibitor for rust protection of rebar reinforcements and an admixture that gives freeze/thaw protection. Our mix design technology gives three times the strength of standard concrete and guarantees a lifetime of durability.
Steel Bracket – The wood column is attached with ½” Grade 5 thru-bolts and ¼” lags to a “U” shaped steel bracket made of ¼” steel (double plated on the bottom). This bracket is robotically welded to steel reinforcement bars (A706 #4 or #5 – depending on Model) that runs the entire length of the column with a hole precast into the base of the column to allow easy attachment of uplift anchors or column extenders. All steel is premium high strength alloy purchased in the U.S.A. and finished with EpoxZi Shield Proprietary powder coat paint.
Strength – Perma-Column® have been extensively tested by both Wisconsin and Purdue University and in comparative strength tests have proven Perma-Column® outperforms the industry standard wood columns. Certified by the International Code Council, the patented Perma-Column® with 10,000 psi strength concrete foundation system lasts for generations.
