CONSTRUCTION SITE CLASSIFICATION

CLASS AStable, non-reactive. Most sand and rock sites. Little or no ground movement likely as a result of moisture changes.

CLASS B: Slightly reactive clay sites. May experience slight ground movement as a result of moisture changes.

CLASS M: Moderately reactive clay or silt sites. May experience moderate ground movement as a result of moisture changes.

CLASS H: Highly reactive clay sites. May experience a high amount of ground movement as a result of moisture changes.

CLASS E: Extremely reactive sites. May experience extreme amounts of ground movement as a result of moisture changes.

CLASS P: Problem sites. The ability of the soil to evenly bear a load is very poor. Sites may be classified as ‘Class P’ as a result of mine subsidence, landslip, collapse activity or coastal erosion. Ground movement as a result of moisture changes may be very severe.  If you are building on a Class P site you will need to consult a structural engineer.

For many sites screw piers is the best alternative foundation choice to prevent future problems in regard to subsidence and shifting. For all construction sites screw piers may be the solution to save cost and time.
