Case-Study – Seawall Stabilization and Erosion ControlAugust 18, 2020
Seawall Stabilization and Erosion Control using Chemical Injection process
LOCATION: Gibraltar, Michigan
Problem: The lake level has risen to a historical high in this area allowing water and wave activity to flood the property regularly and build hydro-static pressure behind the wall and in turn eroded the soil out behind the seawall at the mud line on the waterside causing the seawall to become unstable.
Solution: The client removed the decking and extended the seawall height along with bringing in some fill rock. We then injected the waterlogged soil below the rock with a hardening binder and stabilizer turning the supporting soil to the consistency of concrete without adding weight (this seals the wall against erosion and water infiltration from the base to the cap).
STL Polyjack seawall repair experts have worked on several other waterfront properties without having to excavate them and all our customers are referrable in St. Louis, Lake of the Ozarks area, Gibraltar, Michigan, and many other cities.
