Can anyone please tell me what the deal is with cut & fill. The fall on the block is only slight but. Is there a rule of the depth of fill before you need peers (I think thats what they are called) It may be 300mm of fill. Does this mean I will neeed peers, compacting. Any help, general comments please.
I was told if its under 300 I dont need them eg 300 cut and 250 fill is OK IS there a general rule or is it up to the builder.
Thanks
