can i lay paving slabs on top of grass to put my shed on.?

Answer 1

It depends how long you want your shed to be useful. If you want it to be useful for longer than 6 months, then put down a level cement foundation. This sounds like a lot of trouble, but you may find it to be necessary even to get the blasted thing up. We tried to errect a DIY shed on a mostly level spot (a concrete driveway) and found that for the edges to meet, that it had to be COMPLETELY level. Putting the shed on pavers, even on sand or gravel, will leave you in a better situation than putting it directly on the grass, but over a 6 month period, I'd say that the foundation is very likely to sag, leaving you with a door that won't function, and walls and a roof that gap, letting in the elements. That's not what you want!

Answer 2

I did the same thing last year for my mother - a 6 x 8 shed on paving slabs. But there is a certain amount of work involved. Don't just lay the slabs on the grass. You need to level the area, bed the slabs on sand (making sure they are level) and fill the joints and edges with concrete. This stops the sand escaping. Sounds a little complicated but is easy enough once you start. You may need a bit of muscle to help you though. The slabs can become surprisingly heavy as you lay them one by one, usually having to lift and relay them several times to get the levels right.

Plastic Paving Slabs

Answer 4

I just took off the top layer of grass using a spade and put the paving slabs directly onto the ground. You could use a little sand for leveling if necessary. My shed has been in the same place for 13 years and is rock solid.

Answer 5

You may be better off setting up a more stable base. There may be different thickness of grass under the slab and it settles different. Put some sand or fine crushed stone under the shed. If you think it is not a big deal...then go for it.

If the shed is small, you may want to tie/stake it down to the ground too, lest a wind take it over.

Answer 6

It would depend entirely on the size of the paving slab and shed to be placed on said slab. However, as a professional home remodeler, I would not use paving stones as a foundation for a shed for a variety of reasons. The most important being settling. The stone density may not be adequate for the weight of the shed and its contents. This will cause the shed to sink unevenly with settling. Or, once the shed has settled, it may settle on unseen obstacles (rocks, roots, etc.) beneath the surface of the grass which will cause a tilting effect.

Answer 7

Your slabs will crack if walked on and not level. I reccommend pulling up the grass, levelling and putting down stone screening, 2-3inches. You may have to dig down those 3" if you don't want a step up into your shed. This will prevent (slow down) any grass from coming up and around your slabs that are on the outside of your shed area. This is the good job done, any other way is the quick, easy and what ever, lets just get it up and done way. Which one do you want???
Also make sure it is on a down slope away from the house. (if any where near the house)

Answer 8

Three years ago I did exactly that; I used Weedol to kill off the grass, then spread a thin layer of sand in order to make sure the slabs could be levelled. I then erected a greenhouse on the platform. It has stayed level ever since, and I've had no problems with movement or warping of the greenhouse frame. So give it a go!

Answer 9

You'd be better taking up the grass, putting down some sand and flattening the area off before putting the paving slabs on top.

Answer 10

Caroline is correct.

One of the problems comes from the ground being uneven which can twist the shed over time, the door will not close properly, etc.

You also need to raise the floor or it will rot, most sheds rot from the ground up so even if you put it on paving stones, shove a few timbers underneath the shed floor as an extra barrier and level it up.
