Hello!

We are renovating one of the bedrooms and are considering building a laundry chute, as the laundry room is conveniently located directly below the bedroom in question. The next bedroom to be renovated is also above, and I was thinking of using the same laundry chute through a hatch in a future closet, or something similar.

Since I'm leveling the floor anyway, I discovered that there is some kind of concrete, approximately 10 cm thick, over the entire laundry room. Wire is sticking up in some places, presumably binding some kind of reinforcement. Iron studs are embedded in the concrete.

Anyway, can you make a larger hole in this concrete without any issues? What would be the right tools for this job? Anything else we should consider, has anyone done something similar, how large should the pipe be?

Thanks!

When was the house built?

It was built in 1946
 
Then it should be a standard reinforced concrete slab. The easiest way is probably to contact a company that specializes in cutting holes in concrete. They should be able to cut a round hole with sufficient diameter to drop laundry without requiring special reinforcements.

I'll see if I can find someone who can do that! But even if I could stand on the concrete, isn't the only function of the concrete to act as a cellar ceiling? 10 cm isn't much, and there seems to be some kind of iron framework as well.
 
The local construction company came here and made a hole. It turned out well! The reinforcement consisted of steel wire, more or less.

So the question is… what's the best way to attach a spiral duct vertically? :thinking:
