Mass-Shoring & Underpinning

CMI Structural Solutions was contracted to install underpinning systems, shoring and helical piles for the design and installation of a new elevator in an existing building. Once the existing footings were underpinned, we installed soldier piles, steel sheeting and whalers for the shoring system. After excavating down 6′, 3 1/2″ diameter helical piles were installed to support the new elevator shaft.


Erie Canal Dock

CMI installed 7″ diameter Helical Piles for the support of a new boat dock on the Erie Canal. LiteDeck panels and a structural concrete slab were installed. The dock was 120′ long x 12′ wide with two 20′ wide access ramps.


Lake Ontario Dock

At CMI, challenging projects is what we do! We installed 46- 7″ helical piles to support this 2,110 sq.ft. boat dock on Lake Ontario. A steel c-channel framework was installed to the piles and Litedeck panels provided the formwork for the concrete decking.

Zipline Anchors

The applications for helical piles and Stelcor Micropiles are endless! CMI installed 5″ dia. Helical piles with 14″x 3/4″ Helix to provide anchors for the new zip-line being installed. Each anchor was tension tested to 36,000 pounds. As the anchors are installed, we monitor our digital gauge to determine the torque and capacity of each anchor. These can also be used for guy wires on utility poles and towers.
