Permeable sidewalks #FTW! It’s drenching rain in #WestSeattle this morning and look at the difference between these two surfaces. Better for walking and better for the water table!
Are they as durable as regular sidewalks? NYC is one of the places where people wear the sidewalks out with their feet sometimes before the ice and weather get to it.
@KevinFreitas For pavements they may be a good choice (I'm not a materials engineer). But they are unfortunately not suitable everywhere. They are much less resilient compared to regular asphalt.
@KevinFreitas It's an amazing invention indeed. I don't think I've ever seen it in real life, but the videos I've seen of it looks almost magic.
I'm not sure I agree that it's a positive thing for the climate though. It requires more maintenance (needs to be repaved more often). What climate angle are you considering?
@loke@KevinFreitas Well they permit water infiltration into groundwater so that can counter subsidence and replenish groundwater in an impermeable surface situation. That can be useful if your locality depends on groundwater for municipal water supply.
As for climate specific results from this? Either the groundwater replenishment for resilience or these permeable materials create less or no CO2 compared to concrete or need no hydrocarbons like asphault. But I do not know how they are made.
