This elevated apartment in Saint Simons Island, GA had a sag in the middle of the floor. In order to stabilize the floor properly, our team installed a SmartJack Support System under the area where the floor was sagging, then used that system to attempt to lift the floor into a more level position. In order for the support to remain stable and adjustable even with high moisture conditions, SmartJacks are made with galvanized steel to prevent rusting.
