Not much left of the house. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Next step was to stabilise the soil under the original footings. The original house is set on limestone footings which are in reasonable condition, however as we intend to drop the floor level by about 1.4m into the addition the new slab will be well below the existing footings. Step one is to stabilise the soil with chemical grout injection to a depth of about 1m. We will later reinforce this with a cavity fill wall also. The grout takes 3 days to start to harden and can be shaved into your desired shape in about 5-7 days. It reaches max strength in about 1 month.

Re: OB Project - "New vs Old" - Nedlands, WA 18Aug 21, 2015 6:18 pm Looking good kasra - It's been a while since I have been in the OB forum, but glad I popped back today. I'll be following your thread for sure. Good decision you took those Tree roots out from under the slab otherwise over time it would have just rotted away and that's not good for under a concrete slab. Also think you have made a smart move removing the old Garage. From the photos it didn't look original anyway so not too much damage done Keep the pics and updates coming. https://forum.homeone.com.au/viewtopic.php?f=38&t=44762 My Owner builder journey extending a 1930's Bungalow Re: OB Project - "New vs Old" - Nedlands, WA 19Aug 21, 2015 11:25 pm docker_rob From the photos it didn't look original anyway so not too much damage done Good pick up!! Yes, I'm glad we knocked it over. Also access would have been a nightmare. Re: OB Project - "New vs Old" - Nedlands, WA 20Aug 22, 2015 12:17 am Soak wells installed. Based on our roof area we require 2 x 1500x1500 soak wells. To be extra safe we have decided to place an extra 1500x1500 in the front also. This will give us an additional 50% safety margin over BCA. Most likely overkill. Now comes the interesting part... We are planning on having a 3 quote policy for all trades and this example demonstrates why its very important to take the time to get multiple quotes. Here were the results: 1. Plumber who I had used previously for mainly maintenance - $6900!!! for 3x 1500x1500 installed 2. Earthwork/landscape guys currently working onsite - $5000 for 3x 1500x1500 installed 3. Drainage guy who was referred to me by a friend. - $1500 for 2x 1500x1500 installed Job done!! Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ DIY, Home Maintenance & Repair That laser level looks lovely!
