Building gate pillars

[Lenca]

Hello

I am planning to build a couple of gate pillars similar to the picture. However, not as big as in the picture, but still about 60x60 cm.

I have several pallets of bricks that are more than 70 years old and have been walls on an old barn.

1. How do I know if the bricks are frost-resistant and can be used to build the pillars?
2. I plan to dig out and pack stone at the bottom, is it best to pour a slab then and start building on it?
3. Do I need to fill the empty space inside the pillars?

Best regards

Hello

Anyone with experience in this? Is it possible to do a test yourself to determine if the bricks are frost-resistant?

It will be very difficult to investigate the origin of the bricks, which many recommend.

Best regards

Hello, I'm bringing up the thread again.

Since I found out that the bricks were not frost-resistant, I have chosen to build with lecablocks instead.

I did the following. Dug a hole about 90x90 cm and 70 cm deep. Filled it up with macadam. Made a form and cast a footing 83x83 cm and between 15-20 cm thick. Then built with lightweight concrete blocks 59x19x19.

Initially, the plan was for the pillars to be 80x80 cm, but when we trial-built, they turned out to be somewhat too large, so I chose to go with 60x60 cm instead.

Now to my question, what material can I fill around the foundation with? Can you use 0-18 or does it have to be, for example, 8-16 which drains better?

What is the frost depth in the area?
Avoid 0 material that does not drain. I would recommend something without 0material. If you're worried about frost heaving the post, you can have a ring of insulation around it. However, I think it's overkill in this case. The posts we've made in mountain areas have often been anchored in rock or had a layer of insulation in/under the gravel.
