Failing Lally Columns
The floor system above was originally supported by adjustable steel lally columns located in the basement. Over time, these columns experienced significant corrosion and deterioration, compromising their load-bearing capacity and resulting in floor settlement and deflection. To restore proper support and prevent further movement, a more robust structural stabilization system was required to lift and permanently stabilize the floors.
Sinking Beam
The inadequate support allowed the primary beam to deflect and settle over time, resulting in corresponding movement of the floor joists above. This loss of structural support led to noticeable floor sagging, excessive deflection, and increased floor bounce.
Footings with Rebar
Soil was excavated to accommodate the installation of properly sized concrete footings capable of supporting the required structural loads. Reinforcing steel (rebar) was integrated into the footing design to enhance tensile strength, improve load distribution, and increase the overall durability and long-term performance of the support system.
Footings Leveled
The footings were carefully leveled to provide a stable, uniform bearing surface for the installation of the SmartJack support system.
SmartJack Base Secured to Footings
Once the concrete footings had achieved the required cure strength, the SmartJack base plates were precisely positioned and securely anchored to the footings. The galvanized steel SmartJack columns were then installed onto the bases, establishing a stable and continuous load path capable of effectively transferring structural loads to the reinforced footing system.
SmartJacks Secured to Main Beam
The SmartJack assemblies consist of high-capacity galvanized steel columns designed to effectively transfer structural loads to the reinforced footing system while providing long-term resistance to corrosion and settlement. Following precise adjustment and load transfer, the floor system was successfully lifted and permanently stabilized, restoring structural support and significantly reducing floor deflection and bounce.
