We also paved the garage - but if I had a kind of workshop with it, for tinkering and oil changes etc.. well, I hope you at least planned a tray there so that no oil seeps into the ground.
Paving is good if you only park cars in it. With a workshop and so on, however, not a good decision. I would have preferred to apply an industrial floor coating or polished concrete.
Well, I still want to lay such PVC industrial tiles on the paving in the workshop area anyway. The oil change for the car is done at the specialist workshop. And for the motorcycle, I have a large tray where I have never managed to let anything spill over.
Yes, but your patch will settle relatively soon everywhere, then you will have hollows in the ground, etc. Very impractical for a workshop, I would think carefully about it.
Does anyone know approximately how much such a renovation costs? I have already found quite a bit on the internet, but the ranges were always very wide..
