What Is an Engineered Foundation Under a Mobile Home?

Soil Conditions

• Individually engineered foundations require soil compaction tests to determine the best type of foundation for the manufactured home. The engineer completes soil bearing and capacity calculations, determines resistance to sliding and pullouts and determines frost penetration depth of the specific region when engineering a mobile home foundation.

Customization

• Engineered foundations include customization for the specific manufactured home and take into consideration the footprint of the home, its length, width and height as well as its roof pitch and eventual height above the grade (land surface). Factors for calculations include the weight of the home, its roof loads, dead loads, floor loads and wind speeds of the region for lateral strength and uplift.

Engineered Foundation

• A construction engineer completes the calculations and design for the engineered foundation. Using complicated mathematical equations, the engineer determines the type of foundation needed based upon the data collected for soil, loads, the region and the critical places for support on the home. The engineer creates a series of blueprints that detail the type of material to use and how to build the engineered foundation.
