Only 50mm to 70mm over 1 metre if it's natural ie soil/ grass. Read your engineering, somewhere it will mention slope for hard constructed surface, usually 25mm over 1 m.

Re: Protecting your Slab 535Apr 01, 2020 10:35 pm Take photos every day you have ponding of water and email to your builder every day and remind them of their responsibility to adequately drain and protect the foundation during the build. Tell them that you will hold them personally responsible for any issues you have from slab heave etc in the future. Re: Protecting your Slab 536Apr 02, 2020 6:32 am stevenboh Send a letter via registered mail to the general manager of the builder that explains the situation with dated photos. Reference the exact clause in your contract that says they are responsible for site drainage and ask them to take immediate action to install a temporary agricultural drain in the affected area. Point out if they don't do this they are breaching the building contract. Send a PDF of this letter to your SS, the coordinator and the GM by email. Give the builder notice and a fair opportunity to fulfil their contractual obligation.

However, you will need to organise good drainage along the side anyway and probably its better to manage this so its done properly - not a sloppy, temporary fix by the builder to get a few photos for 'evidence'. Re: Protecting your Slab 539Apr 02, 2020 8:49 am stevenboh Hi StevenBoh Thanks for the photos...but photos alone are not enough as you will need data reference points I recommend you now start taking slab movement measurements these will relate to any future cracking that may occur...best to be prepared BTW, your builder is responsible for your site during the build he has possession Cheers Chris Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: Protecting your Slab 540Apr 02, 2020 4:06 pm stevenboh Thank alot guys, It appears in the contract that I may have to look after the surface drainage : Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ If the builders say that the drainage isn't their problem I may ask the SS if I can have the site handed over to me, as I engage landscapers to build in some drainage It is a requirement in the Australian standards that the builder is responsible for drainage during construction and not to cause abnormal moisture conditions. They have clearly breached the requirements and are responsible for issues relating to abnormal moisture conditions created by them. What is your site classification ? Thanks for the insights, that makes perfect sense, and yeah, I will be leaning on the experience of the excavator operator entirely. 6 16106 4 6194 The concreter will take and reuse.
