With urban sprawl reaching farther and farther, impervious surfaces are becoming more and more of an issue. Sometimes it seems like we are paving the world. Permeable pavers use larger voids and deep stone bases to allow water to percolate more readily into the earth below. Trying to reduce surface run-off, townships are passing more ordinances to limit the amount of impervious surfaces. Homeowners limited on yard space look to find a surface that is more diverse in its use, while also helping to save the environment. Below, we’ll look into the types of pervious pavers and their use.
Benefits of Permeable Pavers:
- Reduce storm water run-off – They keep surface water from overburdening our storm sewers and waterways.
- Reduce the heat island effect – By not using a solid paving, the surface temperatures of the surrounding area are reduced. This is particularly the case with asphalt.
- Helps filter contaminants from surface water – Motor oil, fertilizers, pesticides, and other harmful contaminants can pollute surrounding drinking water sources and harm wildlife. The large stone base installed beneath the paver assembly helps to rid the percolating water of these substances.
- Erosion control – The structure that concrete turf pavers and – plastic permeable pavers provide helps to stabilize soil and gravel areas.
- Encourages adjacent plant life to flourish by allowing easier root growth.
Types of Pervious Pavers:
1. Permeable Interlocking Concrete Pavers – Permeable interlocking concrete pavers provide the most impervious surface. They look more like a traditional brick paver. Soil and grass or a fine gravel typically fill the enlarged voids between them. These types of pavers are typically used in higher traffic areas, where people are looking for a more formal look like roads, parking lots and driveways.
2. Concrete Turf Pavers – Concrete turf pavers allow more water to percolate into the soil than permeable interlocking concrete pavers. They are typically filled with soil and grass, but are sometimes filled with crushed stone. They provide you with a more natural look than the standard pervious concrete brick paver, allowing more vegetation growth. They are used most often in areas less traveled, like overflow parking areas or maintenance/fire access lanes. They are also used in basin spillways, culverts and hillsides for erosion control.
3. Plastic Pervious Paving – Plastic pervious pavers allow the most water to percolate in the soil. They are typically filled with either stone or soil/sand and grass. They are made of plastic cells that when totally established are invisible. Plastic pervious paving is sometimes used in areas less traveled such as overflow parking or maintenance/fire access lanes where the site of a solid driveway are not wanted. You’ll also find this product stabilizing high traffic gravel driveways, recreational paths and/or parking areas where increased percolation of surface run-off is desired.
Permeable pavers have multiple uses and benefits. In a time of increased environmental responsibility, they lower our impact on the surrounding landscape. Implementing this kind of project on your own can prove to be difficult. It is back breaking work to say the least. Not only that, but securing a permit can be challenging as well. Don’t hesitate to call us. As a professional residential landscape construction installer of permeable landscaping pavers serving Bucks, Montgomery and Philadelphia PA, we can help things along. If you can benefit from the use of permeable pavers, decide which type is for you and do your part to help green up the earth.
