Video: Drilled Pier Retaining Wall or Soldier Pile Wall

A drilled pier wall is an example of a retaining wall that you might use when global stability or bearing capacity considerations preclude you from a shallow foundation for a conventional retaining wall. In this video, Joseph Kowalski of RetainingWallExpert.com describes the wall type and presents a slideshow of construction photos of what appears to be a wall in a residential community. This wall uses a cast-in-place concrete wall on top of the shafts with a form-liner to create a brick-like aesthetic finish.

And because of all the fuss, it’s more popular than it would have been otherwise with over 16,000 views at the time of this post. Click through to watch it.

Geotechnical engineers who encounter MSE retaining walls or Mechanically Stabilzed Earth Walls are undoubtedly familiar with the FHWA NHI manual on “Mechanically Stabilized Earth Walls and Reinforced Soil Slopes”. This manual, along with the NCMA manual that is used for non-transportation projects, is virtually the bible for MSE wall design. In late summer/early fall of 2009, a revised version of this manual will hit the streets. Read on for more details.
