Selecting the Right Permeable Paver for Each Project

Choosing the appropriate paver is the first step to ensuring the drainage system works efficiently. EP Henry offers several permeable paver options, including Eco Cobble, Eco Brickstone, and Eco Allegro, each suited to different applications. The choice of paver depends on the project’s needs and the expected stormwater volume.

Eco Cobble is ideal for driveways and parking lots due to its structural integrity, which can handle heavier loads while allowing water to pass through. Eco Brickstone or Eco Allegro might be better suited for patios, walkways, or lighter traffic areas, offering a more refined look without compromising functionality. Selecting the right paver for the job ensures you meet your client's aesthetic preferences and effectively manage water infiltration.

Understanding Site and Soil Conditions

Before laying any pavers, assessing the soil and site conditions is essential. In our area, soil types can vary widely, affecting drainage rates and the overall performance of the permeable paver system. A soil test is critical to understanding how well the soil will allow water to infiltrate, dictating whether additional drainage systems are needed.

If the soil has a high clay content, it may not drain quickly, leading to pooling. Consider adding drainage layers like underdrains or retention basins to help manage excess water in such cases. Alternatively, if the soil is sandy and offers quick infiltration, you may not need as many supplementary drainage measures. Properly evaluating the site helps you design a system that maximizes water management while keeping the project on schedule.

Preparing the Subbase for Maximum Drainage

The success of any permeable paver system relies heavily on preparing the subbase. A well-constructed subbase allows for effective water infiltration while providing the necessary support for the surface pavers. For EP Henry permeable pavers, a layered subbase made from angular stone is recommended, as it helps filter water and supports the weight of the pavers.

Fastening the System With Edge Restraints

Maintaining the structural integrity of your installation over time requires proper edge restraints. These are necessary for the pavers to shift, compromising both the drainage functionality and the project's visual appearance. Be sure to install weather-resistant, durable edge restraints that can withstand our area’s freeze-thaw cycles and prevent the pavers from moving out of place.

Edge restraints also keep the permeable aggregate in place between the pavers, ensuring that the joints remain functional and water can continue to infiltrate efficiently. By installing reliable edge restraints, you’re protecting the long-term integrity of the system and avoiding future repairs that could otherwise become necessary.

Filling Joints With Permeable Aggregate

The joints between permeable pavers make the system effective at managing water runoff. Instead of traditional sand, contractors should use permeable aggregate in these joints to allow water to filter down into the subbase. A clean, angular stone that won’t compact over time is essential for maintaining proper water flow and preventing blockages.

EP Henry permeable pavers are designed with wider joints to hold this aggregate. Once the aggregate is placed, thoroughly compact the pavers to ensure they’re properly seated and stable. This process helps to prevent settling and keeps the system functioning at its best.
