RE: Underpinning (Piering) Project — Final Report
124 River Bend Way
Glenwood Springs, CO 81601
In summary, the concrete foundation walls are stabilized. The push piers were installed in accordance
with the manufacturer's recommendation and specifications.
The two attached drawings show the final post -lift elevations and the amount of lift that was attained. The
"Post -Lift Elevations" drawing can be used as a benchmark for future reference.
The initial laser -level elevation survey done on August 23, 2016, indicated the house was 9-1/4" low at
the west corner adjacent to the garage, compared to the high point at the south corner of the main -level
bedroom. The post -lift elevation survey shows the low point is just 3/4" lower than the same high point in
the main -level bedroom. Thus, the foundation wall elevation difference is now just 13/4" of being level.
Other observations are:
• The interior floor shows slight sag between the foundation walls.
• The interior drywall cracks are in the process of being repaired.
• A few interior doors will need adjusted due to the lifting.
• The kitchen countertop beneath the wall cabinets are within +1/4" of being level.
• Residential Structural Inspections
• Foundation Design and Piering

• The island countertops are only +1/16" out -of -level.
• The two proposed piers at the front porch were not installed. Three previously installed
piers at the porch will be used instead.
• Two extra piers were installed at the garage side of the front foundation wall, while
eliminating a third pier that had failed.
• The damaged wall at the south garage corner is repaired using epoxy that will adhere to
the concrete and to the exposed rebar.
Please call me if you have any questions.
