Browse Forums Building A New House 1 Sep 11, 2020 11:24 am Hi All, If someone could please guide me how should I tackle this.. There is requirement to build a retaining wall around 1 meter high starting from the wall outside of garage.. and the contractor whom I have hired has advised me that he will bolt the C beam to the wall and put the sleepers in.. The total length of the wall will be around 7 meters. As per my understanding it is technically not a good solution as the retaining wall will put its weight on the house wall and not on the base ( which should be around 1 meter deep ) . The reason which my contractor is citing that he does not want to touch/ dig any portion next to slab as it may damage it... and also I think with stormwater pipes already in, he may be trying to avoid extra bit of work... Any suggestions how this should be tackled as personally I want him to dig a hole ( 1 meter deep ) in ground next/ near to slab, pour concrete in and then put beam into it for sleepers to slide into it.

As with any wall over 600mm it would require on of these options usually at 1m high you would need an engineer to sign off on the wall and the footings , he would for sure want a hole dug the same depth as the height of the wall and not attach to the house. Usually walls are meant to be 1m off the boundary Aswell . I would check this first as looks like a new home build and in order to get your final occupancy certificate you would need all retaining walls built and signed off by an engineer Happy to discuss more if you find out those detials Re: Retaining Wall Bolted to The Wall of the House 3Feb 10, 2021 8:39 pm Hi has this wall been approved under DA or a cdc?

I just didnt want to risk interfering with the existing house… 4 11550 Thank you again Simeon.. I will call my certifier for that. Have a good day 4 5197 Thanks for the insights, that makes perfect sense, and yeah, I will be leaning on the experience of the excavator operator entirely. 6 16159 |
