We use the latest in SCC precasting technology. Microfibers add shock resistance and durability. Microsilicia enhances flexural/compressive strength and erosion resistance. A corrosion inhibitor protects the rebar reinforcement from rusting, and a final admixture is added to give freeze and thaw protection. Our special mix guarantees a lifetime of durability.
The wood column is attached to a “U” shaped steel bracket. The bracket is robotically welded to steel reinforcement that runs the entire length of the column. All the steel we use is premium high strength alloy purchased in the U.S.A.
Perma-Columns are three times the strength of standard concrete and in comparative strength tests conducted by Wisconsin and Purdue University, Perma-Columns have proven to outperform the industry standard wood columns.
