Temporary Lally Column Replacement Services

What is a Lally Column?

At A1 Foundation Crack Repair, we specialize in the lally column replacement services and maintenance to ensure the safety and longevity of your property. A lally column, a component in many older buildings, was designed to provide robust support and stability. Originating in the late 1800s, these columns were invented by John Lally in 1898 to address structural failures caused by inadequate support and fire damage. Lally columns are steel support beams that play a crucial role in reinforcing foundations and ensuring the structural integrity of a building.

Types of Lally Columns

• Adjustable Jacks – Hollow, lack strength, and are meant for temporary use
• Brick – Mortar joints decay due to humidity and moisture in basement
