I'm putting up a HDX572. Digging the hole has been quite a job, hardpan was encounter a few feet below the surface and it was alternating jackhammer and backhoe work for two days to get close to the specified depth.
Now, I'm wondering if I'll be able to drive ground rods into that stuff! I have a impact driver with the appropriate driver head but I need a 'Plan B' if, as I expect, the rods won't go in. I can imbed some rods or heavy gauge wire into the concrete (ala Ufer ground) but have heard that if the tower takes a strike the moisture in the concrete could flash into steam and fracture the concrete.
