Foundation Stabilization and Lift

PROBLEM

Located in the mountains of Colorado, this 15 year old residence had settlement occur in the foundation, and resulting damage to exterior facings, windows, doors and casings as well as interior damage to drywall and wall finishes. The home was in need of foundation stabilization and Lift to get it avoid further deterioration.

The owner had recently purchased the home and was referred to CST by a previous customer. CST was contacted to assess the issues with the foundation, and provide a solution to repair the settled foundation and mitigate against future settlement. The homeowner wanted the repairs made on the foundation prior to beginning additional mechanical and cosmetic repairs such as replacing cracked windows, doors, and interior/exterior finishings which needed to be completed soon as cracks and gaps were causing issues with keeping the cold winter air out of the home.

FOUNDATION STABILIZATION SOLUTION

An initial site elevation survey conducted by CST revealed that the home’s foundation had experienced settlement of approximately 2 inches.
The biggest area of differential movement had occurred in the great room and front entrance areas of the home.

CST performed Soil Density tests in order to determine the weak soil zones and set benchmarks prior to designing the injec-tion plan. Once injection locations were determined, CST conducted foundation stabilization by installing a high density expanding structural polymer into the soil, at determined depths. Working from the exterior, with crew members monitoring from the interior great room, the team lifted the settled areas back to original elevation. 

RESULT

The entire repair of this home’s foundation was completed in less than 2 days. CST lifted the settled foundation without causing additional damage to the home and adjusted windows enough that they were able to be latched where previously they had not. 

CST’s repair process is non-invasive and the residents were able to stay in their home during the repair. 

By stabilizing the foundation’s underlying soils, the home was protected against any future settlement or movement, allowing the owner to quickly move forward with completing the mechanical and cosmetic repairs to their home.
