[RE-wrenches] Use roof rock as Ballast for Solar Racking

[Glenn Burt]

I am surprised you can meet the required ballast needs for uplift consistently with the vagaries of simple rock, unless you are performing packaging and weighing of all replaced ballast.

I also see that none of the SolarDock web links work – are they still in business?

Hey Wrenchers,

I’m working on a ballast racking project that has a ballasted roof (river rocks on the roof).   The roof can not support the addition of cement blocks so I am planning to use the river rocks that are already on the roof as the solar ballast.    I have done this before using the SolarDock racking system as it fully encloses the ballast in a tray which keeps the rocks in place.   

 

On the project I did about 6 yrs ago I hired a bunch of laborers to manually bag the rocks and it was quite labor intensive.    Has anyone done this using some kind of vacuum system?   I am hoping there is a better way.   

 

Also - Any other racking suggestions other than SolarDock for this application? 

 

I appreciate the feedback!
