Roof-top balcony, concrete, with kids. Looking for DIY sound-proofing ways, that can handle Tokyo Japan climate...
We have a roof-top balcony (715cm X 384cm / 27m^2 or 23' X 12' 269 sqfeet) which is, like this
, direct concrete slabs. The kids have various toys like Little Tikes car (hard plastic wheels), or golf balls etc. This translate to direct noise to the down stairs neighbour. I have been down there to check and it sure can get rowdy. Socially, it is not a problem, we set a curfew of 20:00 etc, and so on. But at the same time, it is pretty ugly concrete, which turn into a frying pan from June-September on the feet. Why not put down something that would also soundproof.
So, primary a noise reduction event. But it needs to handle Japans rainy season. Not sure it can be too permanent without involving the Housing Estate/Corporation Owner. Also presumably materials easy to find in Japan... I quite regularly have to clean the balcony (scrub off the green moss/algae, that grey clay/powder from the train line)
I've looked at kid's style/cork tiles
- but we've had those before, a little rain, green stuff and it becomes like an ice-rink.
There is Pia-mats
made for soundproofing, and the cow sure looks happy, but I suspect that is supposed to be under-something-else. Black/rubber probably don't work in Summer or rain, right? (Anyone know why its ぴあ? Seems to be a whole category and verb...)
Maybe wood panels, like wooddeckers
which appear to have something rubbery under it. I suspect tiles with bigger gaps like that of nissin
might make the sound from the wheels worse (and I don't know if it has rubber under, they all seem focused on showing the top).
Don't want to break the bank either, and probably something I can lift to clean to ensure we don't get gockis. (Although cockroaches can fly in this country)
(Previous soundproofing ask.me seemed primarily for indoors - this needs to handle some 'weather' - our wooden picnic table/bench lasted 3 years until the wood had rotted through).
