Pervious concrete is a type of structural pavement with an exceptional volume (ranging from 15% to 35%) of interconnected voids. Like traditional concrete, it is made from a mixture of water, coarse aggregates and cement. However, it contains little to no sand, which creates an open-cell porous surface that allows water to pass through easily.
Homeowners May Choose a Pervious Concrete Driveway for Several Reasons, Including:
- They help reduce untreated runoff from discharging into local storm sewers.
- They can help recharge groundwater to boost aquifer levels.
- They can help channel water to landscaping and tree roots, reducing the need for irrigation.
- They help reduce pollutants that can harm sensitive ecosystems.
- They help eliminate hydrocarbon pollution from pavements and sealers.
While They Offer Ecological Benefits, There Are Some Drawbacks to Pervious Concrete, Including:
- They can’t be used for surfaces with heavy traffic flow.
- They require longer curing times.
- They require specialized construction practice.
- It’s hard to determine the water ratio in fresh concrete.
- Conventional concrete tests (compaction factor and slump test) aren’t applicable.
- Special design considerations must be implemented.
- They require regular cleaning to maintain permeability.
In addition to these problems, pervious concrete may not be durable enough for mudjacking techniques, which can repair cracked and sinking concrete for a fraction of the cost of complete concrete replacement. This is an important factor to keep in mind when choosing a specific type of concrete for your driveway.
