perma-columns come in multiple sizes to accommodate
both your solid and laminated column needs
Keep wood out of the ground with precast concrete Perma-Columns, the first product to combine the economy of post-frame construction with the durability of a concrete foundation. Simple installation. No waiting on concrete trucks. No treated wood in the ground. No more rot.
what they're made of
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.

stronger than you think
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.
benefits of perma-columns
A standard wood column can be used with Perma-Columns, no expensive treated wood is required.
The wood column is attached to a steel "U" connection bracket with 1/2" thru-bolts or 1/4" lag bolts depending on application and preference.
Perma-Column's innovative uplift anchor eliminates the need for an added concrete mix in the backfill.
Every Perma-Column is made of 10,000 p.s.i. pre-cast concrete. This is not the standard 3,000-4,000 p.s.i. concrete typically found in foundations. Strength is not the only benefit found in this special mix. 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/thaw protection.

installation made easy!
assembled installation
Streamline the building process with one-step placement and leveling. This technique requires the Perma-Columns (precast lower sections) to be attached to the wood columns ahead of time in a controlled shop environment, and then shipped to the job site with trusses, steel panels and other building components. At the job site, the assembly can be handled the same as a standard wood column, typically set in place with a skid loader.
UNassembled installation
Requires the Perma-Columns to be shipped to the job site unattached, and then set without the upper wood section. Later, wood columns can be attached one at a time or tilted up as an entire wall. This allows for a concrete floor to be poured ahead of framing, and allows many jobs to be started while weather permits and finished during winter.
Splash Board Installation
Perma-Columns require the splash board to be attached using a pre-drilled concrete nail. To do this, drill a 3/16” hole through the splash board into the concrete post 1-1/4” deep using a hammer drill. Angle the drill toward the center of the concrete post to avoid hitting the interior rebar. Drive a 2-1/2” x 3/16” galvanized steel split drive anchor (HW28) into the post until the skirt is secure.
WARNING: Avoid using concrete screws & concrete nail guns because most are not designed for high strength concrete and result in screws being stripped, heads twisting off or surface chipping.
