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.
