20mm Stone Pebbles/Aggregrate

[QuestionsQuestions]

Hi All

I'm about to start a project to make the area under the pergola a stone/pebble garden. As this will be a large area will it work if i use a base layer of cheaper grey aggregate and over lay with the stone effect I want? i.e. to save money use only the expensive pebbles as the top soil as it were.
I've seen new homes builders do this (in fact they don't even use the same colour aggregate - beige with grey over the top - this is where i got the idea) anybody done this and is there any advice/tips you can give me?

Thanks

Thats the way most would do it, you should use a weed membrane under your pebbles to prevent them mixing.

Just to clarify (sorry if its a silly question) but would I put the aggregate under the weed membrane and then the decorate gravel over the top - would it matter what type of aggregate I use (size wise e.g. 10mm/20mm etc) as say 20mm shingle is 44.00 for nearly a tonne so much cheaper than the decorative grey slate i want to see.
Thanks

Use the aggregate under the membrane and gravel on top, a bigger size stone than 20mm would be better if the area is going to be walked on, or if you had cats in the garden.
