Wall Construction Time Lapse
The lapse footage showing a recent job we completed. This video will be featured on our website. This difficult project located in Windham was quite a job. Interstate Landscape started with the removal of an old deteriorating timber wall. The homeowner wanted to create more living space in their back yard so after the wall was removed we excavated back 8ft of the hillside and removed about 120 yards of fill. When we were excavating we ran into three large […]

During Construction Review, the Engineer should compare the actual field conditions and materials to the design drawings. This video is a little longer than most (it’s about 7 minutes) but I promise it is full of good information! Joseph Kowalski, […]

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 […]

Retaining Walls – Layout and Surveying

You never want to have to “move” a wall because it is a few feet from where it should be, right? 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 […]

Retaining Walls Supported in Sliding Soils – How to Prevent a Failure
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

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

Fans of timber retaining walls: you will really appreciate this video. The camera work done by Andrew Yaniuk is amazing. Timber walls are good walls, when designed and constructed appropriately. 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 […]
