Z Series sheet piling shall be used for Z55 Z60 Z70 Z75 and other popular Z65 sections. 3-inch (or 2 x 6) lumber shall be used for single-cleat ladders from 16 to 30 feet in length.The factor of safety against sliding, Z60 shall be determined by summing the resisting forces of the wall which act parallel to the base of the wall and dividing that sum by the summation of driving forces on the wall which act parallel to the base of the wall. If you have some, be sure to pay your homeowner’s insurance.The Z55 state of earth stress in a landslide complex is generally divisible into three components: 2 x 4 lumber shall be used for side and middle rails of double Z75 cleat ladders up to 12 feet in length.The Z65 resisting forces typically consist of the normal force acting on the base of the wall times the coefficient of sliding resistance plus the component of force due to the weight of the Z70 wall and any surcharge loads acting on the wall which is parallel to the base of the wall. It’s everyone’s favorite way to go, much less expensive than other support systems.2 by 6-inch lumber shall be used for double-cleat ladders from 12 to 24 feet in length.

Cold formed sheet pile shall be used on the Z 55 and Z 60 rails between the Z 70 Z75 cleats Z 65.The normal force acting on the base of the wall consists of the component of force due to the weight of the wall and any surcharge loads acting on the Z 55 wall which is normal to the base of the wall plus the component of the Z 60 design lateral pressure acting on the pressure surface which is normal to the base of the Z 65 wall. The coefficient of sliding resistance used to determine the Z 70 frictional resistance at the base of the wall shall be as follows. Anything beyond 4 ft is almost impossible to support with calculations. The Z 75 cleats shall be secured to each rail with common wire nails or other fasteners of equivalent strength.
