Colorado Springs, CO – Repairing a Home’s Settling Foundation

< Back to Case Studies

Challenge

The Wolf residence is a Ranch/Rambler style home on a walkout basement with poured concrete foundation, wood frame construction with stucco and a tile roof, built in 2004 with 4 bedrooms and 3 1/2 baths, measuring 2762 sqft.  The Wolf residence is located in the highly valued Broadmoor Bluffs subdivision in southwestern Colorado Springs.  The soil in this area is highly expansive silty clay mixed with loam.  The home is resting on a hillside.

The Wolfs have owned the home for 8 years and have noticed drywall cracking and an increased amount of separation between the foundation wall and the floor over the past 3 years.  The exterior of the home has increasing sized cracks that range from 1″ wide to 3″ wide depending on the time of year.

The home is experiencing “hillside creep”.  There is cracking and separation between the rear stem wall and basement floor slab.  The Wolfs contacted Peak Structural, INC. after receiving an Engineer Report from Mark McCafferty.  They had been measuring the hillside creep and needed it repaired since the slippage had increased in severity over the last 12 months due to the drought conditions.  The Wolfs chose Peak because we know how to take care of customers’ belongings and property.

Solution

Peak Structural, INC. installed (11) Foundation Supportworks Model 288 Push Piers to permanently stabilize and lift the settled area of the home.  L-shaped foundation brackets were then positioned below and against the footings, and hydraulic cylinders were used to stabilize the sliding side of the home.  Pier depths ranged from about 28 ft to 31 ft.  On average, piers were driven to 4200 psi.  11 piers were installed in 3 days.   The piers effectively stabilized the foundation and restored the home’s value.

Next, 4 tiebeams of an average of 37′ per tiebeam construction were installed from the west foundation wall underneath the basement slab to the east foundation wall.  This Tiebeams will effectively cinch the home together, preventing the west side of the home from sliding downhill.

 

 

 

The project itself was completed within 8 days and the lawn and landscaping around the home were left in good condition.  The installation resulted in permanent stabilization from the hillside creep.  The combination of the tiebeams and push piers tied the home back together and will prevent the home from slipping down the hill that the home is constructed on.  The homeowner was extremely pleased with the results as well as the efficiency and cleanliness of the Peak Basement Systems crew.  Best of all, the engineered system provided peace of mind to the homeowners, now that they know their home is safely supported by a stabilized foundation.
