Structural stabilization of a settled foundation at a townhouse building - Highlights:
A corner of a 4-unit townhouse building has settled due to soil shrinkage, with movements of up to 3 inches. The existing surface soil conditions are suspected of moving with seasonal moisture changes and are unlikely to reliably support the foundations.
We analyzed the structure to determine the factored loads of the building to be supported. We worked with a geotechnical engineer, and a helical pile contractor, to take out necessary building permits at the City of Langley and place deep helical pile foundations to work and support the building and stabilize it.
Even though the project was relatively small in scope, making it uneconomical for many larger consulting companies, we provided a high level of customer service and competent engineering expertise at a reasonable cost to the client. We have the expertise to be versatile to our client's needs.
