Foundation Friday: Case Study: Lally Column Install in Enfield, Ct.

This week’s featured project highlights how New England Foundation Crack Repair worked utilized a structural engineer's report and worked with the local building department to ensure long-lasting support for a basement in Enfield, Conneticut.

The Problem: Load Redistribution After Wall Removal

Our customer worked with a structural engineer who designed a new LVL (laminated veneer lumber) beam to carry the weight previously supported by the removed wall. But that beam needed a dedicated support point beneath it—something strong, stable, and permanent.

That's why the engineer specified the addition of a new lally column resting on a reinforced concrete footing, designed to transfer weight safely down through the basement slab and into solid ground.

Step 1: Precise Planning & Structural Coordination

Before any digging began, our team reviewed the engineer’s plans and verified load paths, beam spans, and exact column placement. Precision is critical—a misplaced column, can affect the structural integrity.

We carefully marked the exact spot for the footing, then excavated a square section of the basement slab to the proper depth. We installed cross-hatched rebar to reinforce the footing and distribute weight evenly.

As this job was permitted and under inspection, we paused at this stage to wait for the building inspector to approve the footing layout and depth. Only after receiving confirmation that it met code requirements were we cleared to move forward with the concrete pour.

Step 2: Pouring the Footing & Inspection

Once the footing layout and rebar configuration were approved by the building inspector, we moved forward with the concrete pour. Using a high-strength mix designed for foundational loads, we filled the excavation with concrete and ensured it was evenly spread and properly finished to eliminate air pockets and voids.

We paid close attention to troweling the surface to match the existing slab height and shape, which not only improves the appearance but also ensures a solid connection between the lally column and the floor. Clean edges and level finishes matter for both code compliance and long-term performance.

Step 3: Installing the Lally Column

The area was then left undisturbed for a full week to allow the concrete to cure properly. This step is essential—adequate curing ensures the footing gains the compressive strength needed to support the new structural load from the lally column.

Once cured, we proceeded with the installation of the lally column, securing it with heavy-duty steel base and Springfield top plate. The column was anchored to the new footing and aligned precisely beneath the LVL beam above.

After installation, the building inspector returned for a final inspection, reviewing both the cured footing and completed column setup. With everything built to code and matching the structural engineer’s specifications, the job received full approval—providing the homeowner with peace of mind and a safe, long-lasting support system.

Final Result

This project is a perfect example of how structural updates—when done right—can enhance both safety and functionality. With the support system now fully reinforced and professionally approved, the homeowner can move forward with confidence in their open-concept space. Behind the scenes, the new column is doing exactly what it was designed to do: quietly and reliably carrying the load.

Make sure your foundation is ready to carry the load. At NEFCR, we coordinate with engineers and inspectors to get it done right the first time.
