Townhouse
Foundation settled
Description of Structure
The project was located in Walker, MN on the shore of Leech Lake. The two unit building, constructed in 1996, is approximately 115' x 50' with a full basement and walk-out facing Leech Lake. The foundation for the structure consisted of typical spread footings and masonry block walls. The upper stories were wood frame construction and were in need of foundation repair.

Notable Problems

Project Summary
Based on observations, there was reason to believe that the building was situated above an abandoned railroad embankment. Borings indicate the fill soils placed in 1996 were likely added above existing fill soils placed above compressible swamp deposited materials.
 |
 |
Success!
Tieback helical piers were used to stabilize resistance piers (as shown at right) so that the footing did not push inward when the basement floor was removed. Each pier was installed and field load tested to a verified bearing stratum 60' below grade. The structural load was transferred from unstable soil to the piers. Settlement was recovered and the structure was restored to the approximate original elevation.

Residential Foundation Repair
Basement wall bowing in
|
Description of Structure The structure was a one story home with a block foundation. The Problem The foundation wall was bowing in approximately 2" on the third course of block from the top. The affected area was 36' long and in need of foundation repair. |
 |
 |
The Solution The fill from along the foundation was excavated. Five (5) helical tieback piers were installed every seven (7) feet to anchor the wall, and pull the wall straight. Once the wall was straightened, 3/4" stone was used to back fill, and 12' layer of topsoil was added. |
Success!
After each pier was systematically torqued in small increments, the wall was perpendicular and integrity was regained

Commercial Polyurethane Application
|
|
Findings: The company contacted RaiseRite Concrete Lifting to remedy the void beneath the control temperature room. RaiseRite sent out an expert in that field to diagnose the problem and estimate the cost for a void fill below the room and above the section of low poured concrete. Raise Rite found that the problem could be fixed using the RaiseRite Technique (RRT) of using 5 lb. high density polyurethane which is injected in a liquid state and then expands to fill voids of all kinds and sizes thus would keep the shims in place that were supporting the room before the polyurethane was injected. |
 |
 |
Success! RaiseRite successfully filled the void under the control temperature room using a 12’ injection tube to evenly distribute the polyurethane under the room and then caulked the perimeter of the room to ensure a proper seal. |
Case Study: Polyurethane Spray exterior basement wall
Description of Project:
Spray the exterior of a bowed basement wall that was straightened to insulate and water seal.
The Problem:
A local resident had recently purchased a home that had a bowed wall in the basement. There were cracks in the wall that were allowing water to seep in due to poor landscaping causing the wall to bow for quite a few years going unnoticed by the previous tenants.
|
Findings: The resident contacted Raise Rite Foundation Piering to straighten the wall using helical piers that pulled the wall into place. Raise Rite sent out an expert in that field to diagnose the problem, estimate the cost to straighten the wall and recommend having the exterior of the wall sprayed with high density polyurethane. The polyurethane will act as a crack sealer, water sealant, and excellent insulating characteristics, as opposed to just sealing the wall with tar which was the previous method. |
 |
 |
Success! Raise Rite successfully pulled the bowed wall back into place and sprayed the wall with polyurethane. The customer was very satisfied and could rest easy knowing that the polyurethane sealed all cracks as well as insulated and water sealed the wall possibly saving the customer from spending more money in the future. |
Case Study: Joint Stabilization
Description of Project:
Joint Stabilization using high density polyurethane.
The Problem:
An area construction company had poured various sections of concrete at a nearby warehouse a few years ago. Due to slab curl and the curing process of the concrete, the sections had begun to move up and down when extreme pressure was applied to the loading dock and aisles throughout the warehouse. The contracting company and warehouse owners wanted to correct the problem so as not to cause more damage to the sections by stabilizing the joints and filling all voids below.
|
Findings: The construction company contacted RaiseRite Concrete Lifting to remedy the voids beneath the loading dock and to stabilize the joints at the warehouse. RaiseRite sent out an expert in that field to diagnose the problem and estimate the cost for a void fill below the loading dock and stabilize various joints down the aisles of the warehouse accompanied by a representative from the construction company. RaiseRite found that the problem could be fixed using the Raise Rite Technique (RRT) of using 5 lb. high density polyurethane which is injected in a liquid state and then expands to fill voids of all kinds and sizes up to 1/32”and also inject the polyurethane into the aisle joints to keep them from shifting when the tow motors drove over them and fill all voids beneath the loading dock. |
 |
Success!
RaiseRite successfully filled the voids under the loading dock and stabilized the joints in the aisles then caulked the joints to ensure a proper seal.
