Stratford Place
This photo album shows the process of a pervious concrete driveway pour at Stratford Place, a 20-lot plat in the City of Sultan, WA (built with an entire pervious stormwater management system).
Pervious has to be poured very dry. It's not unusual to have to pull the material down the shoot.
Placing pervious demands an experienced team. Note the coarse rock base that handles water after it passes through the pervious.
Properly placed, pervious can handle 200+ inches of water per hour.
Covered curing for 7 days is essential.
Pervious shouldn't be handled too much during finishing.
When screeting pervious, use a method that both screeds and compacts the surface.
When placing pervious, do not over work the mix.
When placing pervious, some finish hand tamping and rollering smoothes out surfaces.
When edging pervious, tamp and set edgers; traditional troweling creams over voids.
