After an eternity using a laser and making sure we have a slope of 1cm per meter we now have the base layer done :)
If I understand correctly I now need to rent a machine to compact everything tightly before putting the visqueen layer and the armature.

Is the 1 cm per meter put the draining water somewhere that can take more water ? I suppose I've been seeing a few posts about backyards having standing water during rainstorms and I am somewhat intrigued about the topic atm.

You will want to make sure the slope remains after compacting.

I have foreseen some kind of drainage around with a gravel ditch that leads to our water egress thingy. Though our piece of land usually drains quite well unless it pours for weeks.

I’m taking a mental note of that. More laser fun yeahhhh 🫩

That's awesome. Thank you for sharing it educates as well as inspires.

A French drain?

I think an actual French drain requires some kind of pierced tubing running along the drain. I don’t think I will bother with that.

Ooit eens proberen doen met dit ding. Ik denk dat een laser veel makkelijker is.

Allez nog veel plezier met de verbouwingen!

Il heb ok een van deze gebruik. Slecht slecht expérience. 😅

This is my next nemesis : routing the conduits to my basement while keeping as much as possible of the 12cm foreseen for the slab.
It’s an old staircase when they still needed to shovel coal in the basement. At some point someone closed it roughly with some prefab slab. So clearance is limited if I want to keep it as is and not take it apart (which would be… a long and shifty process).
I’m currently missing about 3cm. I’ll see this week if I can grind them somehow.

One of the coolest French drains I've seen is just breathable yard cloth wrapped around rocks.

Just keeps dirt out of it. And water flowing

Level? That depends on how closely you measure it. See The Coastline Paradox. Now get back to work!

That's is my favorite scene in the entire series!

That’s exactly what I have foreseen :) I saw another post a while ago showing that and I had geotextile in excess so I used it with the remaining of the rocks we had around.

Ho lords… so many crevices…
