Is standard concrete used in making PERMA-COLUMNS?
No! Perma-Columns are poured in a controlled environment using the latest pre-casting and curing technology. Additives are incorporated to enhance strength, density, corrosion and freeze-thaw resistance, yielding a Hi-Dense concrete that has a compressive strength of 10,000 psi! Concrete is the most proven foundation material know to man with centuries of success.
