Foundation cracks admitting humidity: Needs to be sealed on interior/exterior to avoid further damage or water intrusion. You must preserve a good water drainage system to stop these.
They're fundamentally giant galvanized metal shafts with screw-like flanges. To install screw piles, They're twisted into the ground to some depth the torque required to turn them signifies appropriate soil bearing capacity.
Pier Coating: Bare metal might be installed and can consider a very while to rust (manufacturer says 80 a long time +), galvanized looks better and will likely not rust (predicted lifespan is more than a hundred and twenty years)
