Retaining Wall Base Course Installation
To have a level, attractive, well-built MSE wall (block retaining wall) the first course of wall blocks MUST be perfect. The first course must be straight and level, both side-to-side and front-to-back. Any errors in the base course become amplified as the wall is built up. For the leveling course, you need to use a well graded stone that is compacted in place. After compaction, each block should be carefully installed making sure that it is level and it is […]

Also, you want to place the blocks to ensure that you have sufficient room to install the geogrid layers. This video shows some easy ways to help you with […]

If the foundation soils are sliding on a sloping surface of bedrock, then the retaining wall could begin to slide downhill! This 2-minute video shows two ways to prevent this type of global stability failure. Joseph Kowalski, P.E. www.RetainingWallExpert.com Current State PE Registrations

Shoring Wall, Wood Lagging, and Allan Block Veneer
Soldier pile walls with wood lagging can squeeze right up to the property line – and can look GREAT when a segmental block veneer is added to the face. At this property, vertical steel beams were installed. Next, wood lagging was installed horizontally between adjacent vertical steel beams. Geogrid was looped around these wooden lagging panels and then Allan Blocks were connected to the geogrids. Joseph Kowalski, P.E. www.RetainingWallExpert.com Current State PE Registrations

Generous use of well-drained granular backfill will prolong the life of a timber wall. Remember, even pressure-treated timber will eventually decay. The appeal of timber walls is based on aesthetics, cost and ease of construction. (Video notes from Andrew Yaniuk: This is a Time lapse of a retaining wall being […]

Retaining Walls – What is Global Stability?
When dealing with retaining wall design, Global Stability means the stability of the soils above and below the retaining wall. If the soil that supports a wall kicks out, and the wall shifts downhill, that is a Global Stability Failure. This video is a short discussion of retaining wall global stability.
