Steel Soldier Pile and Timber Lagging

IOTA uses vertical soldier piles and horizontal lagging to retain soil walls during deep basement excavations. Soldier pile and lagging walls are a commonly used system for supporting excavations in urban environments.

When working on foundations, building a new structure, or shoring up a heavy soil load, our IOTA engineers, and geotechnical designers often use steel soldier pile and timber lagging walls instead of traditional retaining walls. Using these walls is much more affordable than installing concrete or gravity retention systems. They are faster to build than many conventional systems like sheet piling.

Using a system like a soldier pile requires the oversight of a specialty engineer with experience in soil stabilization techniques and engineering. Often, these walls are temporary, but removal requires the same specialty team as installation.

IOTA Engineering & Construction has an in-house team of engineers, architects and designers that provides soil stabilizing methods like soldier pile and timber lagging. Our technical experts have the experience and knowledge to protect workers, the environment, and the build by properly placing soil retention walls with leading equipment and strict safety standards. We work with our clients to meet the needs of any build no matter the scope or length of the project. Our technicians test the soil and find out what composition they are dealing with before the build begins.

Soldier piles are placed prior to excavation. Typically steel, ‘H-piles’ are drilled or driven at regular intervals along the planned excavation perimeter. The Timber Lagging is placed behind the front piles as the excavation continues. The lagging efficiently resists the load of the retained soil and transfers it to the piles. The walls can be designed as temporary walls or permanent walls.
