Tough step this one. Their are imperfections here and there but poorly accessible and hopefully inconsequential given we will tile over.
The pump
So the concrete alone was €1.351 including the truck to deliver it. The beauuuuuuuuuuutiful pump was €460 but honestly it was so helpful I consider it well spent. Then a couple € because I overestimated my volume by ~0.6m3 so I'll have to pay the recycling tax.
