Pervious Concrete at UNH Stormwater Center

[MrDistrugator]

What happens with freeze-thaw? Also, what happens when the ground underneath moves due to the water flow?

[Forgeable]

I bet it is a bitch when the water freezes in the concrete.

[Nextil81]

Meanwhile, 100 African children die of thirst.

[KiloByte69]

@Nextil81

Don't worry, they'll have 200 more kids to replace them even though the parents can't even feed themselves.

[mdwoods100]

Amazing, I wonder how it wears?

[sausagesnail]

Fake, video is reversed.

[TheJessassin]

@sausagesnail can't tell if troll... or just stupid

[texasmd91]

@sausagesnail You're a moron.

[sausagesnail]

@texasmd91 I have a PHD in neuroscience, I think I know what I'm talking about.

[Okiesmokie]

@sausagesnail I'm sure you've dealt with a lot of pervious concrete while studying for neuroscience.

[armedturtle]

WTF. send that water to africa or my swimmming pool

[calvers7]

I get that this is impressive and everything but did we really need to see three and a half minutes of it?

[carpustin]

@calvers7 Protip: Don't watch all three and a half minutes of it then.

[jbdranger]

when the guy holding the microphone asked for a soundbite from the water, the water replied, "glurgglurglelglurg*

[MrTheomossop]

So, Water, any words for our viewers?

[MrFruitseed]

Where does the water go / how is it controlled?

[climber7777]

wtf?!

[lichottotube]

A zimą? Nie zamarznie i nie rozsadzi?

What about freeze winter? Won't the iced water crack it?

[GetNameError]

@lichottotube

The air voids allows enough room for water to expand.

[EasternCanuck]

@GetNameError that doesn't matter... the ice build up would eventually fill all the holes and destroy the concrete. Any place that goes below freezing would not be able to use this.

[zeruel111]

and fuck tsunami

[michal1337]

sprogniony bo kaca mioł

[mibars]

Cool, cool and then freezing

[dasher1982]

65,232 people have watched this? that's FUCKED UP SON!

[TimNFtWayne]

@dasher1982 : A day later, it's 69,995.

[icyblacktear]

wow this is dumb there's going to be so many sink holes....

[jimmykinkade]

Good thing a reporter from radio was there with a microphone.

"This is the sound of concrete absorbing water. Trust me."

[sappholian]

so what does this do the the re-bar? or have they come up with a support framework that isn't iron based?

[sappholian]

[Lonelan]

....why did they need the sound of the water coming out?

[rickodelico]

I want a roof made of that concrete.

[sodhill]

we use it on tennis courts

[runasv]

I hope the water from they used is some form of grey-water... lol This is great engineering for storm water treatment. Using this also allows LEED certified Buildings to gain a valuable point if they use 50% Previous Concrete for the complexes parking lot. (green construction)

[sidenookie]

what about northern states and freeze thaw resistance... what type of lifespan would this concrete get in that enviroment?

[shamickgaworski]

better than conventional ... google porous asphalt or concrete and read about it or better google UNH stormwater ...

(water sink so even if it freezes it expends down ... conventional asphalt is worse when it comes to breaking due to freezing)

[wazzaa4u]

Wow this is amazing, maybe my group can use this in our presentation on our conceptual design assignment :D

[wehaveadogagain]

Wow! This realy shows Redidrain by Redimix at it's best!

[karreyberry]

Oh my goodness, that's amazing! If I had that kind of concrete at the bottom of my driveway, I wouldn't have to drive through swampland every time it rains! And although the video quality's not great, it seems to be much more attractive than ugly, black, oily, polluting asphalt.

Great demonstration on hydraulic capacity of pervious concrete installation at UNH Stormwater Center.
