Currently renovating an old charming house from the early 1900s. What I want to discuss now is the extension that serves as a veranda/balcony/entrance. The previous owners replaced the posts without supporting the extension, resulting in everything likely sagging a bit with each post that was replaced! The floor on the balcony has a slope of about 3 cm per meter. The new posts are also made of poor-quality timber. Cracking and warped posts. The joists in the extension are also bad. So, I need to redo the work. I want to lift the extension's roof about 5 cm and then replace the posts and install new floors on both the balcony and the entrance level. How do you go about this? I'm thinking of placing three jacks or stamps as per the image and then pressing up the roof. I imagine there will be creaking and noise, but it should be possible. Where are the tools for this?
Jacks are available at Biltema for a cheap price (around 89
, then use regular scaffolding pipes and a makeshift "crossbeam" to avoid damaging your existing, visible beam. Just pump and replace the posts. I have myself moisture-proofed a 1 . 1/5 story house this way, to be able to replace the sill on the house I used the same principle. If it creaks alarmingly much, you may need to take another trip to Biltema and get one or two more jacks. If the length of the poles isn't enough, just add length couplings between them. You can quickly calculate the weight you need to lift, and I believe each jack takes about two tons, so divide the total weight by the number of stamps needed. Go ahead and feel free to show the finished result when you’re done. // Mixar´n

Check with an equipment rental in your area if they have skruvstämp... these are used for concrete casting of slabs and can withstand very high loads... You just insert a crowbar at the handle or sometimes a chain, then you just turn it to the height you want.....
