I am currently considering creating a concrete slab instead of laying concrete pavers for the planned double carport measuring 6x6 m (20x20 ft) and the attached shed measuring 6x3 m (20x10 ft).
The idea came from the carpenter when he suggested building a continuous strip foundation from shuttering blocks for the shed instead of individual pier foundations, which would need to be closed off at the bottom anyway. This way, the wooden structure would be raised above dirt, snow, and water, using the 6x3 m (20x10 ft) shuttering blocks as a rectangular base to support the wooden construction.
That’s when I thought, why not go straight for a concrete slab and add reinforcing steel mesh along with concrete.
Now one thing leads to another, and I’m considering placing the entire carport (6x6 m / 20x20 ft) on a slab as well.
The question is: does this make sense? And how do the cost and performance of a DIY concrete slab compare to paving?
My concrete slab contractor from when we built the house mentioned that a 20 cm (8 inch) thick concrete slab with C25-30 concrete and reinforcing mesh would be sufficient. Special salt-resistant concrete could be skipped, as that would be overkill.
What are your experiences? The whole driveway including the carport and shed adds up to around 180 m2 (1,940 sq ft) to be paved. The rough sub-base/frost protection layer of 0/32 mm (0/1.25 inch) gravel is already in place and well compacted multiple times.
So, it would just need a top layer of fine gravel plus paving or, alternatively, a concrete slab in sections.
I’m quite torn on this: on one hand, I don’t want to spend €30–50 per m2 (€28–47 per sq yd) just to drive over or park on, but on the other hand, I really don’t like the affordable options I’ve seen (grass grids, honeycomb grids filled with gravel) from a visual perspective at all.
If it were a garage, laying simple standard paving inside would be easier (close the door and out of sight, out of mind). With a carport, it’s trickier because it’s open. Also, the price difference between a garage and a carport is no comparison at all.

Three years ago, we also chose a concrete slab foundation for our metal garage instead of paving stones and pier foundations.
The downside is that you still need to cover the concrete slab. We tiled ours; otherwise, the concrete will wear away over time and water will accumulate. Another disadvantage is that our slab is 6 x 9 meters (20 x 30 feet) in size and cannot be easily removed. Heavy machinery would be needed. Paving stones don’t require covering and can be dismantled quickly. Water also drains better through them.
Regards

For the carport and shed, use isolated footings (pad foundations), and for the shed, either pave the area or screw decking boards onto a beam structure. At least, that’s my plan...
the coarse base layer/frost protection made of 0/32 is already sufficient

so we had it paved by the landscaping contractor.Is that a warning device installed in/on the ground to help with reversing into the parking space? - would you like to share more details about it?https://www.instagram.com/11antgmxde/

Hello, no, it’s a simple marten repellent. I often have visitors early in the morning. It also serves as a “driveway boundary” for me — no further, or else I’m in the next room. 🙂 It works perfectly for me both forward and backward.
P.S. The door gap is now sealed, by the way. It just wasn’t finished at that time.
