Browse Forums Building A New House 1 Mar 20, 2012 5:19 pm We are building in Kellyville Ridge. Our plans have been approved by the Ponds Design Review Panel and are currently in with Blacktown Council. We received a call from our builder today to say that Blacktown Council require our piering to be double strength (40MPa) if the piers exceed 1 metre in depth. This could potentially add a lot more money to our piering costs. Has anyone else experienced this?? Re: Concrete Piering 2Mar 20, 2012 5:42 pm If its just increasing the concrete strength it shouldn't be much more. A lot of the cost of piering is related to excavation of the piers and placing the concrete. Basically its a couple of kg of cement per pier in the mix to get a stronger concrete.
