How To Install Fence Posts On Rocks
With chain, concrete wedge anchors, and a little welding, Tim and Renée Grace figured out a way to make a boulder work for them instead of getting in their way when they installed a fence.
The big rock in a steep area on their Tennessee property was right where a T-post should go. Tim started with a steel plate, then arc welded a corner section of steel to support the post and welded a chain link to it. He wrapped the other end of the chain around the post and welded it in place.
Using a cordless 20-volt DeWalt hammer drill, he drilled two holes through the plate into the rock for two concrete wedge anchors to bolt to.
“The post flexes, but holds tight,” Renée says, noting the post would be at an angle if it was bolted directly onto the plate.
After five years, it’s still in place and the Graces have installed a few more posts the same way.
“We installed them in a downhill location crossing a drainage creek fed by a wet weather spring - nothing but rock,” Tim says. “The T-post lays on the ground until we pull wire and start tying it off.”
“It’s a really good solution for tricky, rocky locations,” Renée says.
In areas where there are lots of trees, they run high tensile wire on top to catch falling limbs. The top strand might break, but the fence stays in place.
