Hello Thinking of building prefabricated concrete walls myself

[Rygell]

Hello, I'm planning to build prefabricated concrete walls myself. The construction will be a single floor, approximately 10 x 19 meters. Does anyone know how the construction of the wall should be?

 

[Rygell]

Forgot that they should be isolated

How were you planning to solve the facade?

 

[Rygell]

The facade is planned to be painted concrete, there is some slightly grooved variant. But suggestions are welcome,

were you thinking of casting first and then putting them there?

There are hollow styrofoam forms that you fill with concrete. Then you choose the facade after that.

I was thinking of finishing the walls completely at home. Done something with the facade and a smooth surface on the inside that can be painted. All to reduce construction time on site.

I would think that if you order ready-made, it would be cheaper.

wall construction basically concrete cellplast concrete.

I thought the material cost would not be very high. I plan to build quite a few houses, so my idea was to make them myself.

how have you thought of making the form?
how will you fix the cell plastic in the wall when you cast?
how does it work to lift the finished cast wall?
how do you solve transportation?
how do you solve lifting on site?

I can probably come up with more questions.

I thought that the material cost alone wouldn't be so high. I was planning to build quite a few houses, so my idea was to make them myself

I think it will be both simpler and cheaper to build traditional wall blocks in "wood" if you want to do it yourself. It is quite complicated and expensive to cast with large molds, so if you want a short construction time but still concrete, it is probably cheapest and easiest to buy them ready-made.

The frame of a house itself isn't the most expensive part regardless of the material.

Good luck!

The shape should be solvable. Need to figure out how the construction should be first. Lifting and transport are no problem. I'm currently building with wood right now. But in terms of maintenance, concrete is much better.

but not very pretty. and it locks a lot.
is this going to be a residential building you're planning?

 

[Rygell]

Semi-detached house but two apartments in each building unit. But it's possible to make concrete look quite nice anyway. I've seen some options online.

You should cast so-called sandwich walls in a horizontal position. 7-8 cm of concrete as the outer layer at the bottom, followed by 15-20 cm of polystyrene, and then 10 cm of concrete as the load-bearing inner wall. The concrete layers are held together with stainless steel anchors of various kinds from Halfen. Holes for windows and doors are easily reserved with boxes you craft from form plywood.
You will need to build a casting table in steel with some form of hydraulics to lift and place the wall elements as you go. Alternatively, if you have access to a crane on the construction site.
Check further on tilt-up online.
An advantage is if you start by casting the base plaster and red primer before the first concrete is poured for the outer layer. Then you only need to plaster and color when the house is up and the facade is complete.
As you said, it is a very economical building method.
