Soil Class Chart

MANY ANCHORS ARE DESIGNED FOR PARTICULAR SOIL CONDITION(S) AND ARE UNACCEPTABLE FOR USE IN OTHER TYPE SOILS. WE HAVE LISTED THE SOILS FOR WHICH EACH ANCHOR IS DESIGNED AND APPROVED. SOIL CLASSIFICATIONS ARE TAKEN FROM THE “STANDARD FOR THE INSTALLATION OF MOBILE HOMES”. EACH ANCHOR MODEL LISTED HAS BEEN TESTED BY AN INDEPENDENT PROFESSIONAL ENGINEER TO MEET ANSI A225.1 AND ASTM D3953.91 CODES.

Remember: Each state, county or municipality may require a specific anchor from the groups shown for each soil classification. Check local regulations first.



Note: Prior to installation, refer to any local, state and federal regulations, to assure proper compliance. Soil test probe the anchor location in order to match the soil classification with the proper anchor.
