ᐅ Compacting gravel without a plate compactor

On the right side of this terrace, about 80cm (31 inches) down to the lawn, a small staircase with 4 steps is needed.
It will be built from granite slabs and will be quite a solid block, likely only movable as a whole.
A gravel layer will be used as the base.
Based on my long experience observing construction sites, this layer should be compacted.
For that, a vibratory plate compactor is usually the best choice.
However, since this house is on a slope, and this is an ongoing issue, there is no simple way to get a 50-kilogram (110-pound) machine behind the house. Carrying it down the concrete steps and back up again would be quite a challenge.
The alternative would be a hand tamper — a rod with a flat plate at the bottom — which I would have to borrow somehow, but such a tool does not provide nearly the level of compaction that would be ideal.

I assume there is no solution to this problem and I simply can’t think of one, but maybe I am overlooking something?

Well, construction was done before 1950 too – but there were no plate compactors back then. So there is a solution for your "problem" as well ;-)

Use a 12kg (26 lbs) hand tamper. Instead of compacting 30cm (12 inches) at once, compact in layers of 5 to maximum 10cm (2 to 4 inches). It’s good exercise.

Alternatively, build steps with a lot of concrete and less crushed stone.

There are many options.

If you draw a detailed plan and share it, you might get some help.

P.S. The steps will be very heavy. How will you transport them to the location and how will you install them?

Two people, one holding on the left and one on the right. It's really no problem at all. Unlike the large concrete steps 😉

You can find these plate compactors at your trusted hardware store for a low price. I once bought one for about 30 euros two years ago. They can always come in handy.

Well, a vibrating plate weighing 50kg (110 lbs) is more like a toy. Rent a tamping rammer/jumper, which weighs about 65kg (143 lbs) and can be carried easily by two people (or alone with a good breakfast).
Do it right from the start, and you’ll be done for good 😎

The staircase is about 60 cm wide (24 inches).

Yes, two strong, young men might be a "solution."
I don’t have that readily available. I am over 70, and my social environment is similar.
Of course, you would need two of them twice.

The idea (which I actually hadn’t considered before) will be kept in mind... thank you for that.
