Global Stability includes the stability of the soils BELOW the retaining wall. 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
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
Most building codes require a handrail or a fence if a wall is about 4 feet or higher. So, what’s the best way to get your fence constructed without damaging the blocks or the geogrids?

Drilled pier walls are constructed by drilling a shaft into the ground and then filling that shaft with concrete. The concrete is reinforced with steel. This is an excellent way to stop a landslide when the soil above the rock is sliding downhill. In this video, the piers are 3.5 feet in diameter and go down about 35 feet deep!

Pier walls and shoring walls can be constructed right up against a property line, because they are made of steel or concrete beams with wood or concrete lagging between the piers. But, these walls are not as attractive as a block retaining wall, so we engineered a way to attach the blocks to the shoring wall. The shoring wall is doing the work, the blocks on the front are just a veneer of block, stone and geogrids attached to the […]
