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? -Glenn From: RE-wrenches <[email protected]> On Behalf Of Al Frishman Sent: Wednesday, October 16, 2019 12:42 PM To: [email protected] Subject: [RE-wrenches] Use roof rock as Ballast for Solar Racking 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! Al Frishman EvolvedSolar (917) 699-6641
