Porous Concrete Driveways
POROUS CONCRETE DRIVEWAYS — REDUCE RUNOFF, RECHARGE GROUNDWATER
Porous (pervious) concrete driveways use a special mix design with reduced fine aggregate that creates a network of interconnected voids allowing water to pass through the slab into a stone reservoir base below. This reduces stormwater runoff, recharges groundwater, and can eliminate the need for traditional storm drainage. Pervious driveways help meet municipal stormwater management requirements and are increasingly required or incentivized in the NW Metro area.
Starting at $10 per sq ft
Key Highlights

Why Choose Our Porous Concrete Driveways
Pervious concrete driveways reduce stormwater runoff by allowing rainwater to filter directly through the slab into a gravel reservoir, recharging groundwater instead of running off to storm drains. With increasing municipal stormwater regulations in the NW Metro, pervious driveways can help you meet impervious surface limits and avoid stormwater utility fees.
Signs You Need Porous Concrete Driveways
1. Stormwater management requirement
Your municipality limits impervious surface coverage or charges stormwater fees based on impervious area.
Our Process

FAQs About Porous Concrete Driveways
Does pervious concrete need maintenance?
Yes — pervious concrete needs periodic vacuuming or pressure washing to clear fine sediment from the pore structure and maintain permeability. We recommend annual maintenance, typically in spring, to restore drainage capacity.
