Three distinct tower foundations are available for Martin Aluminum & Folding Towers:
 

Our most popular foundation, the system consists of a hinge base (HB-13/18) set on a concrete leveling footing (CHB-13/18). This foundation allows the entire tower to be assembled on the ground, attached to the footing, and hinged into position. Once erect, tower plumb is easily fine tuned via the leveling bolts on the footing. Exposed parts are galvanized.

An alternate method is to install a fixed (non-hinging) concrete base
(FB-13 or FB-18). The tower's first section and concrete base need to be plumbed and braced before the concrete is poured.
 

For temporary installations, our TF-1300 Temporary Footing employs three earth screws to provide a secure footing without the need for concrete. The TF-1300 is available for M-13 towers. It is used in conjunction with our HB-13. Simply screw base to the ground and hinge the tower into position.
