Complete Novice Needs Help With Sub-Base Patio (with pics)

Postby Egg80 » Thu Aug 08, 2019 8:11 am

Hello all,

I really need some advice having never attempted anything like this before.

I am attempting to build a 28m² patio and so far I have:

Dug out soil to 150mm
Added 5 tonnes of type 1 MOT sub-base
I still need to add another tonne but I'm worried about levelling (with the drop) as the size of the grains are so large (pic 5). Should I order a type 2 MOT instead of a type 1 before compaction?

Also, what's the best way of levelling it? Pegs or stringline? I can't seem to find much guidance for this part.

Thanks in advance.
