We have a provisional sum for rock removal, and was told that the increase chance of hitting rock depends on how deep the sewer pipes are, meaning how deep the excavator have to dig. Would anyone know the trench depth that plumbers dig to connect your sewer pipes and drainage pipe ( the ones that sticks out on top of your site before they pour the concrete slab) to the main pipes (done by the land developer). Just want to know normally how deep the trenches are. I know that the depth of the main sewer pipes (done by developer) is 1.9m. So how deep do the excavator or plumber dig to connect to the main pipe, do they dig 1.9m? Weird questions but hope someone can help. Thank you for your assistance.ReplyReplyLikeShareMoremudmapmudmap7/11/200810:08 am#2mudmapmudmap24 Aug 2008128MelbourneSenior MemberRe: Depth of sewer pipes and drainage pipes2Nov 07, 2008 10:08 amThe depth of the sewer depends on a few things but basically on a flat block you start at the furtherest sewer fitting (toilet etc.) drop 450mm below the slab and grade at 1 in 60 towards the connection to the main. If you block falls towards the sewer main I would say your trench excavation would be approx 1.0m - 1.2m. If the block falls away from the main or the distance will be longer than say 35m you'll use the full 1.9m depth. Hope this helps. Your soil test should have given an indication to the depth of any consistant underlying rock. If they want to claim extra for hitting rock tell them to include a photo in the claim.ReplyReplyLikeShareMorePoloPolo8/11/200812:23 am#3PoloPolo24 Apr 2008292MelbourneSilver MemberRe: Depth of sewer pipes and drainage pipes3Nov 08, 2008 12:23 amhi Mudmap, I appreciate your reply and thank you. My land frontage is 14m and length is 30m. The easement is 2m at rear and the land has about 400mm fall from back of land to front (sloping to front). Soil test is not done because land developer is currently developing the land, so don't know about the continuity of rocks in ground. Looking at the trench of the main sewer pipe that the developer did I can see rock at about 1.7m on one section and rock at 1.9m where the sewer pipe is laid ( I measured the depth). My house cover about just over 50% of land. In your opinion do you think that they need to dig to a depth of 1.9m for the trench?? I believe if they don't dig past 1.5m i could be safe from rocks ( just guessimate) Thanks Mudmap.ReplySign in or Join to reply to this TopicEnd

Yep when I was building my pool in 2023 it was 1k per meter to encase in concrete. The pool builder handled it all and it all went well.
