Single Drill Concrete Pier
For homes and light commercial buildings, single drill concrete piers are concrete columns that are formed by drilling holes into the ground between 9- 12 feet deep and pouring liquid concrete 3500 psi into holes and are reinforced with steel rebars that are tied together and lowered into the hole. Creating a perfect vertical shaft that is between 10-12 inches in diameter.
Double Drill Concrete Piers
For two story residential homes or heavier commercial buildings, double drill concrete piers are 8” in diameter formed by drilling two shafts at a predetermined specified angle, this system works well at most areas because the reversed v angle creates maximum upward support.
