Failing Lally Columns
The above‑grade floors began to sag and lose levelness due to the deterioration and structural failure of the basement's lally columns.
Footing Excavation
Portions of the basement slab and underlying soil were excavated to establish properly engineered footings designed to support the installation of the SmartJack system.
Footings with Rebar
The new footings were cast with a reinforced steel rebar grid to enhance structural strength, load‑bearing capacity, and long‑term durability.
SmartJacks Installed on Level Footings
A supplementary layer of high‑strength concrete was placed over the reinforced footing and finished to a level surface, providing a stable and uniform bearing platform for the SmartJack assemblies to ensure optimal load transfer and performance.
SmartJacks Installed to Main Beam
The SmartJacks-constructed from galvanized, high‑strength steel and designed for full adjustability-were precisely set and tightened beneath the main support beam to restore proper load distribution. This adjustment effectively mitigated floor sagging and eliminated uneven deflection throughout the structure. Unlike traditional lally columns, SmartJacks are engineered to resist corrosion and long‑term deterioration, providing a permanent, stable support system that maintains floor levelness over time. With the structural support restored, the homeowner can confidently proceed with flooring renovations, knowing the system will remain secure and reliable.
