I-Beam Installation Services
Guardian Foundation Repair, LLC offers I-Beam Installation Services in Knoxville, Chattanooga and Tri-Cities!
For below grade walls that have over an inch of displacement or shearing, most engineers recommend installing W6x16 I-Beams anchored to the floor systems above and below with 1/2″ bolts. The gaps between the wall and the I-beam are then filled with high strength mortar to further reduce movement.
The type of I-beam we use is a W6”x16” (unless specified differently by an engineer), anchored to slab below and bolted onto the floor system above with ½ inch bolts. Gaps behind the I-beam are filled with a high strength mortar. In some cases wood blocking must be added to the floor system above to prevent twisting and movement of wood framing. If the blocks are sheered or displaced, carbon fiber is not an adequate repair. I-beams will need to be installed on 4’-6’ centers and in some cases, the wall will need to be filled with concrete.

Common Questions About I-Beam Installation
When does a wall need i-beams rather than carbon fiber?
When a below grade wall has more than about an inch of displacement or shearing. At that point most engineers recommend i-beams. If the blocks are sheared or displaced, carbon fiber is not an adequate repair and beams need to go in.
What size beam do you use?
A W6 by 16 i-beam, unless an engineer specifies something different for the situation. It is anchored to the slab below and bolted to the floor system above with half inch bolts.
What is the mortar behind the beam for?
The gaps between the wall and the beam get filled with a high strength mortar. That closes the space so the wall bears evenly against the beam instead of flexing into the gap, which further reduces movement.
Why would wood blocking be added upstairs?
In some cases the floor system above needs blocking added to keep the wood framing from twisting or moving once the beam is loading against it. It is not needed on every job, but where the framing calls for it, it is part of doing the repair properly.
