Introduction to Permeable Pavement Systems

In recent years paver manufacturers, homeowners, commercial businesses, and contractors alike have become more environmentally conscious than ever before and have taken serious steps to help in the recovery and conservation of stormwater. Lancaster’s area Townships recently have signed an initiative to manage stormwater runoff for the Chesapeake Bay Watershed. For these reasons, cities and townships have come under pressure to reduce water runoff and protect the environment.

As part of the efforts to replenish the water supply by filtering and returning stormwater back to the environment, the installation of permeable pavement systems has skyrocketed in areas where permeable pavers are an option for water management.

1. Benefits Of Permeable Paver Systems

The benefits of permeable pavement include outstanding beauty, easy care, and long-term efficiency, adding value, class, and elegance to your property. They are a great source of storm and water management for residential and commercial applications, allowing water percolation back into the ground, thus reducing the risk of severe flooding. In addition, permeable pavement systems help in eliminating water puddles and keeping contaminating pollutants away from rivers, streams, lakes, and ponds. Permeable pavements also help control ground erosion and speed up the deicing process of snow melting and removal, saving you money in snow removal expenses.

3. Basic Permeable Paver Installation

The installation of permeable pavements systems varies depending on the application where they are to be used as a water management solution. There are three types of PERMEABLE PAVEMENT filtration bases and options to consider while planning your project, full ex-filtration, partial ex-filtration, and no ex-filtration. The base setup and materials needed are distinctive for each function.

–  Excavation: The dept of excavation is subject to the project application and filtration required for the permeable paver system.

–  Geo Textile, impermeable liners, and drain pipes: The installation of geotextile fabric is required for stabilizing the base aggregates. Depending on the filtration base option on the permeable paver system, a drain pipe may be or may not be needed.

– Sub-base aggregates: Must residential permeable systems require a minimum of 6” of number 2” stone, 4” of 3/4” stone. In commercial applications, the amounts will vary according to the system application. A baseplate compactor needs to be run over the 3/4”, without crushing the stone, until there is no visible movement of the aggregate. Contamination of the base must be avoided at all times.

–  Edge restraint: It is the “frame” for the permeable paver system. It can be hidden or exposed depending on the project specifications. It can rest on an open grade or dense base graded base.

–  Bedding course: 1 1/2” – 2” of 1/4” rice stone is used for the paver setting bed. The screed bedding should not be disturbed by pedestrians or construction equipment and must be free of any contamination.

–  Permeable Pavers Installation: Pavers are placed following the chosen pattern design and application of the project. Run a roller compactor or a compactor with a poly pad to set the paver in the bedding base.

–  Joint Fill: The same 1/4” stone is used to fill the joints by sweeping the stone to fill the joints. The surface must be clean of any excess stone before running a roller compactor, preferably, if using a plate compactor then a poly pad should be used to prevent the pavers from being scuffed.

Post Installation Care: Prevent the joints in the permeable pavers’ system from clogging by maintaining them free of debris and fine aggregates. Refilling the joints is part of the overall maintenance of the permeable pavers’ system.
