The MR-SR is NOT designed for rocky or hard soils but is ideal for fair to poor soils

A 90# class pavement breaker/jack hammer is recommended for installation.

The big unknown when installing earth anchors is the holding capacity of the soils. The LL-1 Load locker not only sets the anchor but also tests the anchor at the same time to give you a confirmed load capability.
