I've been pouring over information about sub bases including on this site and asking mates who were in the trade before their backs gave up and going round the houses.
I need 20-25 ton sub base to build up levels 150mm for path and astro. Problem is that this must be slightly permeable to help direct water into a simple drain trench that goes into a sump pit. I'm at the bottom of a hill on heavy clay. Unfortunately everyone Ive spoken to seems to have a different view of what is permeable and what isn't.
Truth be told I don't really want to have to spend well over a grand on 25 ton of type 3 as ground is clay and high water table so ground won't absorb much water in any event. I'm being offered 25 ton of crushed concrete type 1 (not MOT spec) for £250. I'm presuming there will be reduced clay content that will make it more permeable? But then this is just an assumption! Do you reckon just fork out the extra for type 3 or is it a safe (ish) punt to go with the crushed concrete?
Thanks as always brilliant site and a life saver for those of us with little practical experience of how to deal with site problems.

How can this "material" be described as Type 1 but not MOT? It's the same bloody thing!
Admittedly, MOT is a very outdated term, but we all know what it means, and the full name of the "material" is crushed sub-base aggreate to a Type 1 specification of the Dept of Transport documentation.
It can't simultaneously, be Type 1 but not MOT!
