Do you need a crane?
It's not every job that will have the need or the necessary access to work with a crane. Over the years, we have completed many projects with large boulders and a crane is usually the best way to place them quickly and efficiently. Our insurance covers this.
When considering a crane...
Be sure to consider whether the rocks will be placed on or off the liner. You should consider access for the crane at a later date after your landscape, hardscape, fencing, etc. are complete. Sometimes it is better to use manageable rocks on the liner and larger crane-set rocks in the landscape (off the liner). This way you will not need a crane in the future for any possible repairs or changes.
