I'm going to have a 10x8ft shed installed in my back garden. I'm wondering if I should pay someone to put in a concrete slab base or use one of those interlocking gravel filled bases you can get.
I've searched around the web and can't seem to find much information about the pros and cons of using one of the plastic bases – the pros are that I can install this myself and it'll probably be cheaper. Obviously concrete will be stronger, but would it make much difference? I'm not going to putting any really heavy equipment in the shed, but at the same time I want it to last at least 15 years (same as shed warranty).
Perhaps someone with some experience can help here (I have none).

Concrete is impervious to insects and other critters, it is very clean once fully cured, and will not warp or buckle if installed correctly. Of course, concrete is also very expensive and can be upwards of $10 a sqft and should normally be professionally installed unless you're a pretty advanced DIY'er.
Gravel bases and gravel filled plastic can be a good alternative, but they have a few downsides. It's easier for moisture to get in. Gravel will keep out larger pests, but insects can find their way in. Dust will be a lingering issue but if you start with clean gravel it shouldn't be terrible. It will be more likely to move since it's not one solid panel of material.
The plastic panels can be a good choice for a light-duty shed and will give it a more natural feel. Which should you choose? Well, I can't tell you that, but hopefully this info helps.
