ᐅ Which type of garage floor is best suited for easy cleaning and resistance to dirt?

Hello everyone,

The strip foundation for our double garage is already completed. Now the gravel is being prepared, and then the floor slab (probably 15cm (6 inches) thick) will be poured.

The driveway in front of the garage is about 8m (26 feet) away from the street. So far, the contractor has laid the gravel so that the floor slab will be approximately 10cm (4 inches) above street level. However, he recommends 15cm (6 inches) and therefore suggested an additional 5cm (2 inches) of screed or similar material to reach this height.

1. Question: Is screed suitable for a garage floor, or should we raise the floor slab by 5cm (2 inches) and install an industrial-grade floor covering? According to the contractor, the raw floor should not be left as is, because, for example, saltwater in winter could damage the floor.

2. Where is the usual position for a finishing strip at the garage entrance? For example, with a sectional door. Should the floor (e.g., screed or industrial floor) be laid up to the inner edge of the walls at the garage entrance, with the exterior/paving stones installed slightly inside the garage entrance (i.e., accounting for the wall thickness of the garage entrance)? If so, this would need to be considered during the slab formwork.

Best regards

1. Correct. However, you can also grind the concrete, which saves you from having to apply a coating. This coating can sometimes be very expensive, around 100 euros per m2 (11.5 square feet). You only need a screed if you plan to install tiles.

2. That is exactly right. The formwork is set up so that paving can be done right up to the inner edge of the block.

This has often been done incorrectly and still is. It only takes the construction company about 5 extra minutes to avoid extending the formwork straight through...

Does this (100 €/m²) refer to the "sanding" or the "coating"?

Sorry, that was unclear. These are the costs for the coating. Sanding costs approximately 20 euros per m2 (10.8 square feet).

There is liquid PVC or "garage coating" available in buckets. Check at Norma. You paint it onto the floor and it is oil resistant.

I would put two small electrical conduit pipes on it. I would also extend them a bit up the walls instead of using baseboards. Done. BüFa has something like that. So does Brillux.
