Using boulder as pier footing?
Hi DIY OBS folk,
I’m thinking about setting up a permanent pier, and possibly OBS around it in the future. Bringing in large amounts of concrete for pier footing etc will be difficult on my property. Mega anchors look good, but I need to do more research on them. There is, however, a large boulder, likely 2-3 tonnes in a good spot. Just wondering what you think about drilling into the boulder to mount a pier and then building a deck over rock & around pier?
Drilling may be very difficult, but another boulder has a drill hole through it so it can be done. I’m not even sure how I would anchor into holes?
Plus Would thermal issues from rock radiating heat be too much of a problem, even with deck shading it?
I welcome any advice or criticisms on the idea.
Thanks
