Square vs. Round: yes, the shape of your piers does matter, a lot.
You may be thinking ‘come on, it can’t really matter if the piers are square or round’ but I can assure you. It does.
Supportworks helical piers use round steel tubing, and round shafts usually have a much higher installation torque rating, so that more force can be applied when it is installed. A Round shaft’s steel area is located outward from the center of the shaft, this makes a much higher resistance to bending.
In comparison, a square helical pier uses a socket and pin coupling. Couplers are designed to be pulled tight (in tension), not to hold up weight (in compression), especially not the weight of a home. That’s because the reason why they were built was to hold wires in the ground for cell towers and light poles.
In conclusion, use round Helical piers to keep your home up.
