Should be a human right 😅 Thanks!

House built in 1944 and 0 cracks anywhere so i think im good :) thanks alot!

Thick enough? You mean i should have 2meters of concrete? It doesnt seem like you are in construction mate. Yes, concrete does absorb water. The reason behind this is that concrete is a highly porous material that is made up of gravel, sand, cement and water. The final product appears hard but is full of pores.

Concrete burns even if it starts raining on it. Pouring. You often water a new slab to make it not cure too fast, in that case it will crack.

A packet soil ground is always the first start,under the concrete, and when you can level that you can skip the bottom concrete, (since it has no use at all). That way i save money, work, and height in this low-ceiling bathroom.

Thick enough? Concrete is not hydrophopic. It gets wet and soaks water mate.

Easier to work on a concrete slab than? A packed sand/stone floor? Just a waste of money pouring 2 concrete slabs imo. Theres no problem packing and leveling without concrete

Concrete does not stop moisture. The walls go further down than the floor does so that doesnt make a difference

To be able to put floor heating on it, + it has an insulation property. You cant put floor heating on styrofoam, so you need a layer of something else. And these boards are stuff and sturdy and are approved for floor heating, theyre perfect

THANKS LISA!

Haha, its safe. Everyone has it here

Haha, thank you very much :)

She said "meow".

No xD

I do not care about waterproofing a basement with concrete walls that needs to breath, both in and out. Otherwise you get a mold problem.

Very close

XD the "p-trap", is that a water lock? That is in the drain, under that big lid. Which country are you from? Ive never seen a air vent so close to every drain ever in sweden. We may have 1 or 2 air-vents/backflow thingies in a whole house.

I dont think you know how this works. As i said earlier, you cant rubberize a somewhat damp basement with concrete walls. Concrete needs to breath, especially in basements. And to be real, why do you see a need for a waterproof system in a basement with concrete everywhere? Really no point.

The ground is solid. Thats always a first step, even if you build a parking garage. The 2 layer foams, with boards on top, which are pretty sturdy if youve never worked with one, is kinda tough. And 12mm slab ontop which also filled gaps and what not. Dont be that guy, it holds up my bathtub with no problem, and my daughter jumps and plays without a crack.

You cant use a waterproofing system on concrete walls in a basement. The walls needs to be able to breath. We tested this in this exact bathroom like 8 years ago. We used the kiilto rubber in the shower and on the wall. But the concrete gets a little damp sometimes so the rubber comes off. Its a different story building in a basement than a new drywall - box

We packed the ground - insulaton - plastic - boards - floor heating - leveling concrete. The leveling concrete slab flows down into cracks and edges and fills most up. Yeah if a underground mega earthworm comes im in trouble x)

Copy that

Under the insulation. Well, for what rly? And then another layer conceling the floor heating? Well, you gonna have to drill. Clothes hanger, showerwall, shelves etc.

You mean a trip-fall-toekiller curb? No thx ^^

About 2 meters. We are kinda short so its np ^^

The concrete board is very light, doesnt weigh much at all. It like coated with concrete on each side, with kinda like glassfiber net, and some sort of styro inside of it. Pretty hard.

It was kind of a test. Layered from bottom - Sand and stones - styrofoam - plastic sheet - boards - concrete. The leveling concrete also flowed into edges and stuff so it filled every pocket.

Thanks daddybear😄

I did know what i thew away. But i have a bunch of clear ones laying around aswell.
