Browse Forums Paving & Concreting 1 Oct 05, 2010 4:11 pm Hi My stormwater system was completely blocked and I had to dig up my concrete driveway and then dig about 10 metres of trench (roughly 700mm deep and 600mm wide) to access the damaged storm water pipes. Having done so, I replaced all the old 90mm pipes with 100mm pipes. The ground has a high clay content but no rocks of note. I have now decided to replace the concrete driveway with clay pavers (230 x 115 x 50). As I understand it though, I need to be very careful about how I fill the open trench before paving. My plan is to cover the new 100mm SW pipes with 100mm of river sand (200mm in total), compact it, and then progressively fill the remaining 600 - 700 mm with road base, compacting (by hand) every 100mm. Is that the way to go or is there a better way? I definitely do not want to end up with a sunken driveway and I want to get it right. Thanks John Re: Preparing to pave a driveway 3Oct 07, 2010 6:06 am Your on the right track, did you dig the whole drive or where the trench is ?
