Hello I would like to build a garden house with aerated concrete and a gable roof. The area is approximately 15sqm.

Now my question is which foundation I need.

Slab, strip, point reinforcement?

And the most important thing for me is the foundation. What basically goes into the 80cm pit? Sand?

Thank you

Hello knock88 Set up a formwork for a foundation, put in proper reinforcement and pour it. Remove the formwork, fill the pit with RCL (compacting well in layers) and place a 15cm floor slab on it. Also put in proper reinforcement. This should last for the next 500 years. Steven

Okay. Simply into the pit recycling and then proven base slab.

How deep does the pit have to be and how many cm recycling?
What about xps insulation, construction foil, separation layer?

Thanks

Hello knock88

I assumed that the pit with a depth of 80cm is already there. If not, it is sufficient to dig the foundations to 80cm. Do some formwork and pour with concrete. Don’t forget the reinforcement. Remove the formwork, dig 30 cm. Fill and compact in layers with 20 cm of RCL (of course only if it is allowed in your area, otherwise use gravel). Then 10 - 15 cm of concrete on top. The RCL/gravel is capillary-breaking. Under the concrete slab, a good foil (rot-resistant). That would be sufficient for a garden house. Of course, you can also put Styrodur under the base slab. Then you should dig accordingly deeper.

Do I now have to dig a pit of 80cm or 30cm?

Hello knock88

make a strip foundation. This should go 80cm deep (frost line). When you have completed the foundation, you dig a pit 30cm deep. The RCL goes into it and the floor slab goes on top.
