Two Rivers Seawall Repair



Problem
The seawall in Two Rivers was constructed with wooden sheeting. With the lake
levels down for a few years, this wood dried out and when the levels
returned had rotted. This allowed the material behind the wall to erode.
As this material eroded, the grade that went up to the house which
supported the deck, began to sag.

Summary
The homeowner who had many years ago already invested in piering
his home for support, was proactive with solutions to repair his riverside
home and the beautiful deck he had built. The first quote was for
installing new metal sheeting to replace the failing wooden sheeting.
He was shocked to find that there was nearly a 2 year waiting list to
complete this repair. Quoted just over $190,000, this repair would have
taken three months to complete.

Solution
RaiseRite Concrete Lifting, Inc., used the Deep Foamjection™ process
to stabilize the soil to support the deck and prevent further erosion
and loss of soils. Deep Foamjection™ is the process of injecting foam
to specified depths to increase the load bearing capacity of the soils.
For this project RaiseRite installed 16 injection points approximately
5-10 feet under the ground. The foam used for this project was crucial
because a truly hydro-insensitive foam was needed. HMI Hydrofoam
was specifically designed for jobs where water or moisture is present.
This 4 lb. per cubic foot foam was designed to set up in the presence
of water and to maintain dimensional stability in wet environments. This
job was quoted at $10,000, saving the customer $180, 000. This process
took the RaiseRite team one day to complete (8 hours) compared to 3
months it would have taken to install a new metal sheet-piling seawall.
