So, the land developer offered to do the site cut free of charge when I purchased the block, which has been done and I went to look at it and I am concerned they may dug too deep. The land has approx a 2m fall from back to front.

When I go to the back of the block, the depth of the cut is approx 2 metres. I know that there is a fall on the land and I don't know how thick the slab will be but the cut at the rear seems too much, actually overall he seems to have taken too much out.

I know they can fill this but does anyone have any ideas about site cuts and slab thickness etc? I am a first time builder so I have no idea.

Cheers.

Do you already have a builder for your home? Best to speak to them, they are the one's who should determine how much cut/ fill you require and they will draw up your plans according to your block.

Also where is your sewer situated? We were supposed to cut and fill as we had a small fall of 0.5m back to front, meaning we would cut in around 300mm which is not a lot. But now we have had to change our plans to raise the slab 200mm, therefore only need minimal cut (less than 100mm) at the back of the block but all fill at the front of the block, due to the fall in the sewer which is at the back of the block.

Maybe you could also speak to your local council/ water board about specific requirements related to your block. Sorry I am not much help as the builder has looked after these issues for us, which we wern't aware of when we bought the block. We also arranged to get a certificate 149 (NSW) which lists requirements for our block for our pool builder. It cost $55.

Good luck!
