I have now bought sealing slurry, which I will apply to the base slab before installing the dimpled membrane (again, and more carefully than the workers). In terms of dimpled membrane, the simple version is probably sufficient, but I will likely choose the manufacturer "Dörken." It was recommended to me because the material is supposedly high quality. Somehow the price differences have to be somewhat justified. The terrace, front entrance, and driveway to the garage will be paved flush with the house. So no 20-meter gravel strip. Personally, I usually find the curbstones ugly. Many neighbors instead set the regular paving stones in a concrete bed as a boundary. This would have the advantage that there would also be a path around the house. Which of you still had the woman with the "expensive gravel taste"? [emoji6] I am now also looking for decorative gravel. I haven’t really found anything suitable yet. I would like round, gray-anthracite colored gravel with a minimum size of 1.5 cm.
