But what is interesting... check the monorail beams just in front of the MK and in the TTC plaza area. They look far better, as though they semi-recently gave them a paint job in those areas. Since pressure cleaning is out of the question, it appears they could at least paint the areas of the monorail that go over the guest area plazas and in-park areas. Seems it can be done...
I doubt it, and it really shows in some areas. :hurl:
Well its quite a ways up to use a pressure washer along the tracks around the Kingdom.
Also a problem with power washing concrete is you are wearing away at the material with each cleaning. Hurricanes and other inclimate weather do enough damage already. So I'm sure Disney wants to make sure the tracks & beams last as long as possible within the structural safety parameters. Those are not cheap fixes
This is the first I've heard of power washing damaging the structural properties of concrete. And I'm an architecture student who has taken building materials classes as well as two architectural engineering classes. Think this would be something they might mention.
Not sure what type of power washers you have used, but concrete is an extremely durable building material, which is why it's used for highways, bridges and buildings, and it is not easily weathered.
Even conventional concrete can withstand over 6000 psi (though there are grades of concrete 2500 psi, 4000 psi, etc.), and reinforced concrete (which the monorail track certainly is) can withstand up to 10 times that. High-powered professional power washers sometimes can create up to 3000 psi.
In my opinion, they must be dirty for reasons other than they are afraid a power washer would damage the track irrevocably. There could possibly be some minor cosmetic damage. :shrug:
