How to level pavers in preparation for shed?

Hello all,

I have purchased a shed online and am wanting to install in the corner of my backyard atop of some concrete pavers that are preexisting (see image). They're currently not level and slant down towards the fence line.

What are the steps I should take to level this surface? I am told it will be a pain to have to pull these pavers up and level the dirt/sand below so open to other suggestions but also want to do it properly.

For the internal shed floor, I am planning to use pavers inside as well to secure it down and make sure the internal contents are not sitting at water line.

Thanks,

BFraser

Hi @BFraser,

Welcome to the Bunnings Workshop community, it is fantastic to have you with us.

Unfortunately, the only good way to level the existing pavers would be to lift them, add a material like roadbase to the low spots, level and compact it with a tamper, then reinstall the pavers.

I suppose if you were going to elevate the shed floor using pavers, you could construct a pad of new pavers over the existing pavers and bed the new pavers with mortar. It would likely be easier now, but if you ever wanted to remove the pavers in future, it would be a lot more difficult.

Let me know what you think.

Hi JacobZ,

Thanks for your response!

You've given me some ideas to consider. option 1 is probably the better way of going about it but option 2 does seem like less hassle for current state.

Hi @BFraser,

I would roughly level that corner with concrete mix.

Erect and bolt down the shed.

Yellow tongue flooring leveled with window spacers & building adhesive.

Come back if you are interested in that approach for more details.

Thanks @AlanM52,

I'm interested in your approach. Could you please elaborate on how to level the yellow tongue floor using window spacers?

Planning & Prepping:

Flooring-

With the door opening in mind we need to cut the sheets (maybe 2 or 3) so they can slide in on a angle and then laid down on the pavers and... end up so the overall length (when butted together) is a neat fit - lengthways.

Cut the sheets, prefit to check all OK and put aside.

Packers-

We will call the spacers (one or more) a pad.

Using say a 30 x 30 cm grid pattern mark the pad locations with chalk (X) so the flooring has even support.

Use a 4' spirit level and a longer straight length of timber that will fit in through the door to level the pads.

For each pad use one or more spacers so all the pads are level, this is a dry fit no glue.

Check again that all the pads are level, go back and fix the spacers (one or more) with building adhesive.

Next day lay down the flooring sheets, be careful not to knock the pads.

Cheers
