Build pillars for a gate?

[Johan Larsson9794]

We are going to install a 4m gate with a motor for our entrance road. We want this to be mounted between two pillars, like the one in the picture.

How does one build such pillars oneself? Can someone explain?

It's a long gate, weighs many kilos. What kind of gate are you thinking about? Double type or a whole one that opens inward or a sliding gate?

Do you mean gate posts? Made of wood?

The classic way is to go into the woods and partially debark a pine and let it stand for a year or two. Then cut it down and saw the timber to size.
Nowadays, you can avoid that part of the work by purchasing pressure-treated wood if you find it in the right dimension. Or saw suitable pine timber to size and take it to a pressure treatment factory to have it treated at a cost.
In any case, you should use sturdy posts for a 4-meter gate. I would guess about 8x8 inch timber. Such heavy pressure-treated wood can be a bit hard to come by, but it can be done.

Normally, you dig a hole by hand as tightly as possible and at least 1.5 meters deep. Place the post in the hole and brace it so it stands straight, then pack stones around the post all the way up to the ground surface. Stones that you can lift by hand. You "jontar," meaning you stamp them together with a log to really fill all cavities and wedge them in place.

You can cast a concrete foundation that ends 10 cm above ground and has very sturdy flat irons (for example, 10x150mm) sticking up to bolt the gate post in between.

You "jam" them, meaning you stamp them together with a piece of wood so they really fill all the voids and are wedged in place.

You can cast a concrete base that ends 10 cm above the ground and has protruding very strong flat iron bars (for example 10x150mm) to bolt the gate post between.

No, the picture I linked to is probably stone with plaster? That's what we want at least.
