There are various materials used here and there.
One is caulking
Another one is urea foam
Its functionality is good
Caulking has advanced technology starting with acetic acid and non-acetic acid to non-polluting and fire prevention.
Urea foam is also a really good material
Good use and function because it has the advantage of foam
By the way
It is used incorrectly.
Reduce labor costs
The deadline is sloppy, it's wrong
Use for blindfolding
Than the purpose of the material
Write as a fluke.
Board electrical distribution box
It is a so-called toad house electric box.
If you dig concrete like that
Fill the side with cement mortar
Should be fixed
?Urea foam is over time
When the chemical performance drops
The foam shrank
Then that box
Because it can't be decided, I rattle.
A building built by chance
Can't last long
Last year, as a friend of the owner of the building
The construction was in a mess, so I had to stop the construction three times.
<This is a series of insolvent construction>
Power is nothing without Control!
