Limestone Boulders for piers

Postby Thebogman » Tue Sep 08, 2015 6:17 am

Hi,
New member, keen to learn more about walling ;)
Looking to build a dry stone wall at entrance to my house, and have access to some huge boulders 6 foot long x4 foot wide

My dad reckons two of them would make great entrance piers and then build the rest of the entrance wall out from there..
Wall will be all weathered limestone to tie in with an existing wall along the site boundary

Trying to gauge how boulders would look instead of traditional piers, has anyone done this before or any advice if we go this route?

Cheers,
Thebogman

Welcome along,

Sorry I cant help myself, I would have thought you could make it look good. Best of luck lifting them.

Nigel.

Why not? Sounds like a great idea. Any chance of an image?

Big boulders well set in the ground were a way of ending many walls in the SW of Eire and were almoste always the only way when you'd built a wall with vertical placed stones.

To look good they need to look reasonably matched and even.

thanks all, will send on some pics once I find a nice evenly matched pair.
I assume if i want gates will just need to sink some posts tucked behind (when viewed from the road) the two pier boulders...

Don't forget that you lose a lot of height once they are dug into the ground.

The joys of modern internet connections. Instant replies. |A month apart!!

If the stones are set vertical with a flat enough facing each gap, then it is possible to drill gate hangings directly to the stones themselves - providing that they are sunk well enough into the ground to hold the gate permanantly horizontally.

A 12 steel tubing gate should hang OK when fixed to, for example a 1ft square post sunk to 2ft 6inch in clay. Obviously a softer soil/subsoil will need deeper. 3ft square 'posts' probably won't need anywhere as much as that - but I don't know.

Thanks for the replies, the new plan is to drill them for gate hangings alright, have two pretty decently matched blue limestone boulders onsite now (they are a good 7-8 foot long so hopefully should be able to have enough rock above ground to hang the gates)

Serious rocks :)
