Sinking Bridge Lifted In Fertile, MN

Challenge

Jeff, of Fertile, MN, reached out for support with the local golf course, Sandhill River Golf Course. A 16ft. wide cart bridge on the course needed support, as the soil beneath was settling and the bridge was becoming unsafe. Design Specialist Richie went to take a look at the issue after Jeff contacted us for a FREE estimate. After a thorough examination, Richie recommended that Jeff and the club invest in helical deck piers. These plates use proven structural engineering technology proven for years to repair damaged foundations and overcome problems caused by weak and unstable soil conditions. Weak or unstable soil close to the surface isn't a problem because piers can be driven to reach strong, stable soil at greater depths. Jeff was happy with the proposal, and we got to work!

Solution

Foreman Jose and his crew installed 4 of our Helical Piers, designed to create a solid supporting base that transfers the structure's weight downwards to strong supporting soils. The helical-shaped plates on the shank of a helical pier are engineered so that the pier can be turned into the ground like a giant screw. Rotational resistance is measured as the pier is installed to ensure that the pier is solidly anchored in the soil. Our helical piers were installed to lift the bridge back to its original position. The team mechanically screwed sections of the helical pier into the soil. Once the pier met its depths, our crew installed foundation brackets below the footing. The weight of the bridge was able to transfer through the helical pier to deep soils. Lastly, Jose and his crew replaced the soil to make sure the space looked neater than when they found it.
