Pervious Concrete by Legacy General Contractor
PERVIOUS CONCRETE — PERMEABLE SURFACES FOR STORMWATER MANAGEMENT
Pervious (permeable) concrete contains little to no fine aggregate, creating a porous structure that allows water to pass directly through the slab into the subbase and ground below. We install pervious concrete driveways, patios, walkways, parking lots, and pedestrian areas. This reduces stormwater runoff, recharges groundwater, and can help projects qualify for LEED credits and stormwater management requirements.

Residential pervious
driveways, patios, and walkways that allow rainwater to pass through instead of running off.
Commercial pervious
parking lots and pedestrian areas that reduce stormwater runoff and may qualify for LEED credits.
Stormwater compliance
pervious concrete helps meet municipal stormwater management requirements.
Groundwater recharge
water filters through the concrete and subbase, recharging the water table naturally.
Why Choose Our Pervious Concrete
Pervious concrete requires specialized mix design (little to no fine aggregate) and installation techniques. Our crews are trained in the unique placement and curing requirements.
Proper subbase design is critical for pervious concrete. We install aggregate reservoirs beneath the slab that store and slowly release water.
We help clients navigate stormwater regulations and determine where pervious concrete can replace traditional concrete for compliance.
Signs You Need Pervious Concrete
1. Stormwater management requirements
Municipalities increasingly require reduced stormwater runoff. Pervious concrete is an accepted solution.
2. Standing water on hardscape
Pervious concrete eliminates puddles by allowing water to drain directly through the surface.
3. LEED or green building certification
Pervious concrete contributes to LEED credits for stormwater management and heat island reduction.
Our Pervious Concrete Process
Step 1 — Design
Calculate required storage volume and infiltration rate. Design aggregate reservoir subbase.
Step 2 — Subbase Installation
Install aggregate reservoir layer with proper depth and drainage for water storage.
Step 3 — Pervious Concrete Placement
Place pervious concrete using specialized techniques — minimal compaction to maintain void structure.
Step 4 — Curing
Cover immediately with plastic sheeting. Pervious concrete requires careful curing to maintain its porous structure.

FAQs About Pervious Concrete
Does pervious concrete clog over time?
Pervious concrete can accumulate sediment in its voids. Regular vacuum sweeping or pressure washing maintains permeability. With proper maintenance, pervious concrete performs well for 20+ years.
Is pervious concrete as strong as regular concrete?
Pervious concrete has lower compressive strength (typically 2,000-3,000 PSI) than standard concrete. It's suitable for driveways, parking lots, and pedestrian areas but not heavy structural applications.
