Hi,
Just after some advise with sub base materials. It's a large area roughly 90m2 where I will be laying 125mm sub base and then a layer of loose decorative stone.
The sub base needs to be permeable so standard mot type 1 is no good. Has anyone used the mot type 1 reduced fines as an alternative especially as I'm struggling to get the type 3, or am I better with 4/20 grades sub base.
Thanks
