Hello everyone
I have a garden shed with a footprint of 6m x 2.5m, which is 15m² (161 sq ft). Since I want to create a walking area all around it, the foundation will expand to 8m x 4.5m, which is 36m² (387 sq ft).
At first, I thought about making a full concrete slab foundation, then building an underlying frame from squared timber on top, and placing the garden shed on it. This would also secure it firmly in place.
However, I must admit that the cost of the concrete slab would already exceed the price of the garden shed, and I feel this might be overkill.
After contacting the garden shed manufacturer, they said a simple slab foundation made of paving slabs would be sufficient. However, I definitely want to anchor it securely.
So here is my planned approach:
I will create a slab foundation using paving slabs. Beneath them: 15cm (6 inches) of crushed stone, 5cm (2 inches) of gravel or grit for bedding, then the slabs on top.
At the corners, I will drill down 20cm x 80cm (8 inches x 31 inches) and make isolated pad foundations.
The squared timber frame will be anchored at the corners through the paving slabs into the pad foundations using bolt anchors. The squared timbers that form the inner frame (supporting the floor above) will only be laid on the paving slabs and not screwed down.
Now my questions:
1. Is it problematic to anchor only the corners?
2. Do I need a frost barrier (frost skirt / frost protection) around the slab foundation?
Thank you very much
Best regards, jumbo125

Great! That sounds very good. Silly question…. I’ve thought about it too, but can I drill into a curb?
I was thinking of drilling and using anchor bolts… but won’t it break? You can drill into curbs. We used standard anchors (I think 8mm or 10mm, but I don’t remember exactly) with suitable screws. Plan to drill more or less in the middle of the curb.

You can drill into the curbstones. We used standard wall plugs (I think 8mm or 10mm, but I don’t remember exactly) and matching screws. Plan to drill roughly in the center of the curbstone. Great, thanks. I’ll choose a wide one on purpose!
So, do you also mean drilling from the top down (into the narrow side)?
