Definitely need your engineer to approve the two-pour slab in writing before you let them pour the top. I enjoyed reading your website regarding waffle pod slabs. Coming from Perth I've never actually seen a waffle pod slab, it's all raft slab and footings over here. Thanks for the feedback Chippy. I've put a lot of effort into the website and I'm glad it's helping people. We haven't got all the answers but we try at least to raise awareness of some of the problems. Matt Slab is waffle pod (375mm pod + min 100mm 20ma concrete) on approx 45 bored concrete piers to 200mm depth stiff soil with concrete paths front and sides (except where garage wall is as it is 200mm from boundary). Any suggestions for long term maintenance of the slab? Especially down the garage side? The E class was because the long term estimated settlement of the fill at 25mm plus the reactivity of the soil of 50mm equals 75mm. Thx Re: Can beans and slabs be poured at different dates? 8Dec 30, 2018 9:39 pm cornellengineers Hi sweetswisssteel i had a look at your previous posts and you\'re already pretty aware of the issues. Three things to consider. Drainage. Drainage. Drainage. Keep moisture away from your house. The bored piers should account for the effect of the fill settling - expect to see gaps forming under your footing as the settlement occurs. The gaps aren't so much a worry as what the settlement does to your site drainage. Monitor, maintain and work with your neighbour to ensure the 200mm wide slice of land between the garage and the boundary is free-draining. The original setup of the drainage is on your builder - how you maintain it is on you. Enjoy your home. Matt Otherwise I will keep an eye on the drainage , I have 9 yard drains including under taps. Thx Hello needing some advice. I was about to build my Alfresco and needed a new slab and remove exisiting slab as its not standard. So they start to excavate and jackhammer… 0 10702 my suspicion - some builders, they do usually make 'odd' settings in their site plan / pricing as their standards - being hopeful that first - the initial price is… 9 2508 yep you need a joint, foam is easiest, will look fine once rendered with a joint. 2 5243 |
