Also known as “rain gardens” or “storm water planters”, bioretention ponds are intended to gather natural water runoff from walkways, sidewalks, parking lots, and other types of pavements. They are widely used in the commercial and municipal construction industry, but can also render several benefits in the residential market.
Continue reading to learn more about bioretention ponds and ponding issues, as well as, what to do if your pavement quality is declining as a result of improper drainage.
Water Damages and Ponding Issues
Water is not a friend to pavement. Insufficient drainage often leads to an overabundance of water penetration, which can weaken pavement overtime, causing a wide range of damages. Fading, discoloration, cracking, crumbling, fracturing, splitting, and developing uneven surfaces are just a few common damages that can be caused by water accumulation or improper drainage. After some time, these damages can also lead to hazardous circumstances for cars and pedestrians. This may lead to accidents, which can result in liability claims and lawsuits.
Ponding issues are another problem with insufficient drainage. “Ponding issues” refers to water pooling or puddling in a paved lot. This is usually a result of improper installation, old age, or some form of structural damage (i.e. car accident, construction, natural disaster, etc.). Pooling water is not something you want to see on your pavement because it can cause internal damage to the bonds that hold asphalt together. This eventually leads to all of the damages mentioned above, with the addition of bleeding, raveling, rutting, and more.
Even seal coated pavements are subject to water penetration and damage. Although sealcoating is designed to protect pavements from water, it cannot do its job forever without routine maintenance and periodic re-sealing. For this reason, it is important to always monitor your paved surfaces to ensure they are not taking on these kinds of damages. Taking early action is the best method of avoiding costly, tedious, and invasive paving repairs.
As for bioretention ponds, they are a terrific solution to storm water runoff and water damage prevention. They are man-made fixed depressions in landscaping that use engineered storm water control methods to direct water runoff, safely and effectively. However, they require the right soil conditions. Proper soil conditions can help reduce pollutants in groundwater, as well as, slow down the flow of water, or allow water to seep into soil.
Bioretention ponds that contain soil with contaminated groundwater cannot allow water to seep into the underlying soil. In these cases, the ponds are implemented in a way that directs excess water into temporary pools, where it is then filtered and discharged into the local sewer system. In areas where storm water has a tendency to pool, a bioretention pond is needed to collect water runoff.
Not only do bioretention ponds collect storm water runoff, thus prevention pavement damages, they also promote increased water quality, improve the structural integrity of permeable surfaces, and even enhance curb appeal. Furthermore, they are easy and inexpensive to install. Just be sure to hire a licensed, bonded, and insured Indianapolis paving company for expert service you can trust.
