Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Permeable and porous surfaces are the same thing. | While both terms refer to materials that allow water to pass through, there is a difference between them. Porous surfaces have small holes or gaps that allow water to seep through, while permeable surfaces have larger pores or spaces that enable water to flow freely through them. |
| All hardscape materials can be permeable or porous. | Not all hardscape materials are created equal when it comes to their ability to let water pass through them. Some common examples of permeable hardscaping include gravel, pavers with large joints, and open-cell concrete blocks, while porous options might include brick or natural stone with irregular shapes and sizes. |
| Permeable and porous surfaces require more maintenance than traditional hardscaping options. | While it’s true that some types of permeable and porous hardscaping may require additional upkeep (such as cleaning out debris from between paver joints), they can also offer benefits such as improved drainage and reduced runoff during heavy rain events – making them a worthwhile investment for many homeowners looking for sustainable landscaping solutions. |
| Permeability is the only factor in determining whether a surface is environmentally friendly. | While allowing water to penetrate into the ground is an important aspect of eco-friendly landscaping practices, other factors such as material sourcing, durability over time, and overall impact on local ecosystems should also be considered when choosing hardscaping materials. |
