Hi,
I'm running a 25mm MDPE pipe under my driveway, but a few meters of it will have to go quite shallow (about 10") due to underground drainage and wondering what ducting I could use? I've looked at the Twinwall stuff but you can only get it in 50 or 100m coils, also I wondered if there was anything more rigid? I could use rigid soil pipe but when I concrete my drive next year, would the brown soil piping hold up about 2" of clay, 4" of type 1 hardcore and 4" of concrete?
Thanks in advance.
