United States Environmental Protection Agency (EPA). Washington, D.C. "Field Evaluation of Permeable Pavements for Stormwater Management, Olympia, Washington." Fact Sheet. October 2000. Document No. EPA-841-B-00-005B. Open-graded friction courses (OGFC) are a porous asphalt surface course used on highways to improve driving safety by removing water from the surface. These use an open-graded mix design for the top layer of asphalt. Unlike a full-depth porous asphalt pavement, OGFCs do not drain water to the base of a pavement. Instead, they allow water to infiltrate the top 3/4 to 1.5 inch of the pavement and then drain out to the side of the roadway. This can improve the friction characteristics of the road and reduce road spray. [26] Single-sized aggregate [ edit ] Please note some larger products are delivered to kerb-side (the street outside your home), it is at the drivers discretion if they can deliver the item to another location on the property. A soakaway is essentially a large hole in the ground which is filled with large and course aggregate where rain water collects and then slowly seeps away down into the soil.

Now that we know the broad types of drainage options available we can examine the advantages and disadvantages of each specific types of driveway or patio. Gravel-based permeable paving, often incorporated with recycled plastic grids, is another versatile option. It is ideal for a natural, rustic aesthetic and excels in areas prone to erosion. The plastic grids provide structure and stability to the gravel, preventing displacement from foot or vehicle traffic. Brattebo, Benjamin O.

Retrieved 2023-01-29.Gravel is by far the cheapest permeable hard-landscaping option. It comes in many colours, depending on where it was quarried, and can be bought in bags or by the tonne. You can also buy recycled products, such aseco-aggregates, which include by-products of the ceramics industry. With the appropriate design and installation, porous asphalt pavement can have a lifespan of more than 20 years. Maintenance of the asphalt surface requires regular quarterly vacuuming to prevent clogging by sediment and debris. A wide variety of edge restraints are available and range from timber to plastic to concrete to steel or aluminum as well as cut stone

Grass pavers, plastic turf reinforcing grids (PTRG), and geocells ( cellular confinement systems) are honeycombed 3D grid-cellular systems, made of thin-walled HDPE plastic or other polymer alloys. These provide grass reinforcement, ground stabilization and gravel retention. The 3D structure reinforces infill and transfers vertical loads from the surface, distributing them over a wider area. Selection of the type of cellular grid depends to an extent on the surface material, traffic and loads. The cellular grids are installed on a prepared base layer of open-graded stone (higher void spacing) or engineered stone (stronger). The surface layer may be compacted gravel or topsoil seeded with grass and fertilizer. In addition to load support, the cellular grid reduces compaction of the soil to maintain permeability, while the roots improve permeability due to their root channels. [5] Single-sized aggregate without any binder, e.g. loose gravel, stone-chippings, is another alternative. Although it can only be safely used in walkways and very low-speed, low-traffic settings, e.g. car-parks and drives, its potential cumulative area is great. [ citation needed] Porous turf [ edit ] Grass pavement A study published in the Journal of Environmental Management highlights the effectiveness of permeable pavers in reducing stormwater runoff. If you do choose to pave, go for permeable products that allow rainwater into the ground below. Here are just some of the materials available. However, do visit your local builders’ merchants or DIY store as you may find more options. Permeable pavers are an excellent choice for homeowners looking for a sustainable, aesthetically pleasing way to pave driveways and walkways. They help in managing rainwater runoff and can enhance the beauty of the property. Parking LotsThe major advantage here, other than the obvious environmental benefits, is the fact that rain water is FREE and can save you huge amounts on mains water, particularly if you are on a metered supply. Porous asphalt pavementdoes not require proprietary ingredients and does not require special paving equipment. General paving contractors typically have the necessary equipment to install porous asphalt. The performance of porous asphalt pavement is similar to that of most other asphalt pavements. Like other asphalt pavement, it can be designed for many situations.

Drainage– Rainwater drains through the cavities, reducing the risk of puddling and flooding which helps meet SuDS (sustainable drainage system) requirements.There are a few other things that will affect what you can do and the suitability of a permeable driveway. Here are some of the most common, but for a very detailed look at all planning factors involved see the guidance from the Precast Concrete Paving and Kerb Association.
