COMMERCIAL: BRIDGE RESTORATION – WISCONSIN
Project consisted of flattening the bridge deck and adding architectural stone to the abutments and parapet walls. The revisions to the bridge deck plus the new masonry required the addition of helical piers to increase the load capacity of the abutments. Work also included shoreline improvements and resurfacing of the asphalt pathways leading to and from the bridge.
The PierTech helical piles consisted of: 4– 3 1/2″x10’x12″x.475 Helical Piers. Pile design 25 kips compression load.
4x 3-1/2″x10′x12″x.375″ helix galvanized helical piers
4x 3-1/2″x10′ extensions galvanized helical piers
8x 3 1/2″x5′ extension galvanized helical piers
4x kit 3-1/2″ TRU-Lift bracket with slider
1x 3-1/2″ painted adapter drive tool
RESIDENTIAL: FOUNDATION REPAIR – FLORIDA
This residential project required a quick and permanent solution to the foundation settlement problem. Helical piles were needed to stabilize the structure built on poor soil. The PierTech helical piles and TRU-LIFT bracket were brought in to satisfy the project demands.
The PierTech helical piles consisted of: 50 – 2 7/8” (0.217wt) X 8”, 10”, 12” Helix 3/8” thk 21’ long. Pile design 50 kips compression load.
The PierTech helical piles were installed around the perimeter of the foundation at approximately six foot on center. These galvanized helical piles were installed to an average depth of 21 feet and terminated in load bearing strata. 50 piles were installed using 12k PierTech drive head. The house was raised to allow for pier installation and lowered once complete. Once the pile installation was complete, the TRU-LIFT bracket was used to stabilize the foundation.
BOARDWALK NEW CONSTRUCTION – MINNESOTA
Minnetonka Wetland Nature Preserve boardwalk project.This design build development required a quick, vibration-free solution that would not disturb the wetland surroundings. PierTech Systems helical piers were brought in to satisfy the project demands.
The PierTech helical piles consisted of: 230 2 7/8” (0.260wt) X 8”, 10”, 12” Helix 3/8”thk 20’ long. Pile design 20 kips compression load.
The PierTech helical piles were installed in pairs of two over 1600 linear feet. These vibration free helical piles were installed to an average depth of 20 feet and terminated in load bearing strata. 230 piles were installed using a 12k PierTech drive head. Once the pile installation was complete, cross bracing was attached to each pair and the boardwalk was assembled on top
