MBSSS Helical Post Base

MBSSS Helical Post Base is a full displacement deep foundation for support of sound walls, light poles, signs, towers and other structures where the primary loading condition is overturning or lateral shear. The standard capacity offers greater economy for many applications. Helical Post Bases offer all the advantages of a helical foundation in that they do not produce drill spoil or cause vibrations during installation. They do not require concrete and the sign, light post, or other structure can be mounted to the foundation immediately after installation. They are ideal for rail corridors, rural areas, along highways, and near bridge/overpass approaches. Slotted top plate and four bolt moment connection allows adjustment in position and inclination. Patented design with novel geometry and side cutting teeth reduces installation torque and improves penetration into tough ground conditions.
