Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Polymeric sand is always better than regular sand for permeable pavers. | While polymeric sand can provide some benefits, such as increased stability and weed prevention, it may not be the best choice for all situations. Regular sand allows for better water drainage and can be more environmentally friendly. The decision should depend on factors such as climate, soil type, and intended use of the area. |
| Permeable pavers don’t need any maintenance once installed. | Like any outdoor surface, permeable pavers require some level of maintenance to ensure they continue to function properly over time. This includes periodic cleaning to remove debris that could clog the pores in the pavers and prevent proper water drainage. Additionally, if using polymeric sand, it may need to be reapplied every few years depending on wear and tear from foot traffic or weather conditions. |
| All types of permeable pavers are equally effective at preventing stormwater runoff. | Different types of permeable pavers have varying levels of effectiveness when it comes to managing stormwater runoff. Factors such as pore size, depth of installation, and overall design can impact how well a particular type of paver performs in this regard. It’s important to choose a product that has been tested and certified by an independent organization like the Interlocking Concrete Pavement Institute (ICPI) or ASTM International for its ability to manage stormwater effectively. |
| Installing permeable pavers is too expensive compared with traditional paving methods. | While there may be additional costs associated with installing permeable pavement systems initially due to materials used or specialized labor required; these costs are often offset by long-term savings in reduced maintenance needs or lower utility bills due to decreased demand on municipal infrastructure during heavy rain events. |
