Most concrete septic tanks do not have waterproofing. I explain: why did I decide to coat my "construction", and why from the inside?

Nothing in our world lasts forever, and even concrete corrodes over time. The only question is how long will it take, and is there any point in defending yourself against it?

Of course, when you do something for yourself, you want your creation to serve as long as possible, especially when it comes to building your house and all the adjacent communications.

But it often happens that "a good thought comes after" ...

And I was convinced of this in my experience as a self-builder, not once.

❗ Waterproofing my homemade septic tank is one example.

All articles about building a septic tank with one hand, read on my channel.

It is not difficult to coat the concrete walls with mastic, but in my case there were some nuances.

My inexperience is the main one.

The moment I poured my concrete box, and it stood on the surface, it was necessary to waterproof the walls from the outside. But I just didn't think about it at that moment.

It may sound stupid, but when there are a lot of thoughts in your head, you sometimes miss something. Even important ...

And yet, the fact that septic tanks smeared outside are rarely found here played a role. How many examples I have not met with a septic tank from the same concrete rings, the vast majority were simply buried in the ground, without any protection.

And then an example comes to mind with ordinary wells.

How many decades do they stand and not fall apart? Yes, they can be overgrown with something, but to partially or completely collapse - this is unlikely.

But still, I decided to make protection from the inside.

The natural environment is one thing, but the environment inside the septic tank is quite another.

Anything can be there. Of course, super chemicals and acids will not be there, but even household waste and hygiene products can more seriously affect the body of the septic tank.

✅ How that a layer of bitumen mastic will definitely not be superfluous.

Plus, we exclude the possibility of waste getting into the ground.

But still I wonder if there is any sense in all this, and how much will a wall with a thickness of 100 - 150 mm actually collapse?
