Permeable Pavers

Permeable interlocking concrete pavers (PICP) are a specialized paving system that consists of concrete pavers laid over layers of differently sized stones or aggregates. These specific layers work together to filter and direct stormwater into underground aquifers. Beyond managing stormwater, permeable pavers also help mitigate the negative effects of drought, providing advantages not only for homeowners but also for builders and the wider community.

Benefits of Permeable Paving | Eco-Friendly Pavers

• Reduce Water Demand: Installing pavers over grassed areas can help conserve water, as less irrigation is needed.

• Enhance Landscaping: Permeable pavers minimize erosion, especially in areas where grass is dry or has died, helping to maintain the landscape's integrity.

• Prevent Standing Water: These pavers eliminate surface water accumulation, reducing potential mosquito breeding sites.

• Increased Property Value: A driveway with permeable pavers can enhance curb appeal and may increase property value due to its functional and aesthetic benefits.

• Heat Reduction: Permeable pavers often have a cooler surface temperature compared to traditional asphalt or concrete, reducing heat buildup in and around your driveway.

• Erosion Control: By managing water infiltration, permeable pavers help prevent soil erosion around the driveway and nearby landscaping.

• Enhanced Durability: These pavers are designed to withstand heavy loads and traffic, making them a durable option for driveways.

Permeability on Driveways

Permeable pavers are an excellent choice for driveways due to their ability to manage stormwater, reduce erosion, and contribute to a more sustainable environment. Using permeable pavers for driveways is a practical and environmentally friendly choice that offers long-term benefits for both homeowners and the surrounding environment.

Permeable Paving Solutions

Permeable pavers are becoming increasingly popular among homeowners seeking eco-friendly and aesthetically pleasing landscaping solutions. Ideal for walkways, patios, driveways, and other high-traffic areas, these pavers enable the creation of sustainable landscapes that harmonize with the natural environment.

Designed with distinctive spacer bars and wider gaps between the stones, permeable pavers allow rainwater to pass through and naturally absorb into the ground. This design prevents runoff from flowing into storm drains, reducing the risk of flooding.

Installation Guide | Permeable Pavers

Site Preparation

• Excavation: Remove the existing surface (e.g., asphalt, concrete, or soil) to the required depth, usually around 12-24 inches, depending on the expected load and soil conditions.

• Subgrade Preparation: The base soil (subgrade) is compacted to create a stable foundation. It's important to ensure the subgrade has the correct slope to direct water flow.

Installation of Base Layers

• Geotextile Fabric: Lay a layer of geotextile fabric over the compacted subgrade. This fabric prevents the layers from mixing and provides additional stability.

• Base Layer: A thick layer of large, angular stone (typically 2-3 inches in size) is added and compacted. This layer acts as a reservoir for stormwater.

• Intermediate Layer: A second layer of smaller, angular stone (usually 3/4 to 1 inch in size) is placed over the base layer and compacted. This layer further aids in water filtration and provides a stable foundation for the pavers.

Laying the Pavers

• Bedding Layer: A thin layer of fine gravel or sand (typically 1-2 inches thick) is spread over the intermediate layer. This bedding layer helps level the surface and provides a base for the pavers.

• Placing Pavers: Permeable pavers are then laid on the bedding layer according to the chosen pattern. It's important to ensure proper spacing between the pavers to allow water to pass through.

• Joint Filling: The gaps between the pavers are filled with fine, angular aggregate, typically 1/4 to 3/8 inch in size. This material allows water to pass through while keeping the pavers in place.

Compaction and Finishing

• Compaction: Once the pavers are in place, the entire surface is compacted using a plate compactor to ensure the pavers are firmly set and level.

• Final Inspection: The driveway is inspected for evenness, proper alignment, and any necessary adjustments are made. Additional joint material may be added after compaction if needed.

Edge Restraints

• Edge Restraints: Install edge restraints along the perimeter of the driveway to keep the pavers in place and prevent shifting over time.

Maintenance Considerations

• Regular Maintenance: To keep the driveway functioning effectively, it's essential to periodically clean the joints and refill them with aggregate as needed to maintain permeability.

This installation process ensures that the driveway remains durable, functional, and effective at managing stormwater runoff.
