The Benefits of Permeable Paving

The Benefits of Permeable Paving

Typically homeowners deal with outdoor water in a variety of ways. This must be done, otherwise your home will be damaged by water. And you never want that to happen because repairs are always expensive. 

For most, an uncovered drainage system and maintenance is sufficient. Another popular method of dealing with outdoor water is permeable paving.

Permeable paving is a type of outdoor foundation that uses a variety of construction materials to accomplish one purpose: allowing water to flow through its surface. Non-porous materials usually direct water to storm drains, but surfaces made of porous materials help water flow through openings between materials. Porous materials have several advantages. For example: It also acts as a filter for pollutants and solid particles from water passing through the surface. Permeable paving is an excellent solution for water conservation, which is why residential and commercial sectors alike are using it now more than ever. In this article, we will shed some light on permeable paving.


A few words about permeable paving

Generally permeable paving is done on large walkways or driveways. A critical step in the process is placing a 6-inch gravel bed foundation beneath the porous material to hold the paving structure in place. The structure itself has four levels. Each of which plays a role in filtering stormwater.

First layer: The actual ripening material
Second layer: A gravel bed
Third layer: Filter fabric
Fourth layer: A bed of sand to keep the structure from shifting

What are the materials used in permeable paving?

Seven materials are used in permeable paving. These are:

1. Brick
Commonly used in brick paving is a perforated paver with gaps between each brick.

2. Crushed stone/gravel
It is the cheapest paving material because it is usually decomposed granite or gravel. This allows rainwater to seep into the small pieces of rock.

3. Dry Lay Pavers
Dry-lay pavers, also known as dry-laid pavers or sand-set pavers, are paving stones that are laid without using mortar or any adhesive. Instead, they are placed on a prepared surface such as compacted sand or gravel. Joints between pavers are usually filled with sand or fine gravel.

4. Grass paver
The permeable surface of grass pavers allows rainwater to infiltrate the soil, reducing stormwater runoff and helping to recharge groundwater supplies.

Also, plastic mats with cells are quite useful.

Benefits of Permeable Pavement

Permeable pavement offers several benefits, particularly in the realm of stormwater management and environmental sustainability. Here are some permeable pavement benefits:

Stormwater Management: Permeable pavement allows rainwater to infiltrate through the surface and into the ground, reducing runoff and alleviating strain on stormwater infrastructure. This helps to mitigate urban flooding, erosion, and pollution of water bodies.
Groundwater Recharge: By allowing water to infiltrate into the ground, permeable pavement helps to recharge groundwater supplies, maintaining aquifer levels and supporting the health of local ecosystems.

Pollution Reduction: Permeable pavement filters pollutants such as oil, heavy metals, and sediment from stormwater runoff, preventing them from entering water bodies and contaminating the environment. This helps to improve water quality and protect aquatic habitats.
Temperature Regulation: Permeable pavement tends to absorb less heat than traditional pavement, reducing the urban heat island effect and moderating local temperatures. This can help to create a more comfortable and sustainable urban environment.
Reduced Flooding Risk: By allowing water to infiltrate into the ground, permeable pavement reduces the volume and velocity of stormwater runoff, lowering the risk of flash flooding and drainage problems in urban areas.

Longevity: Properly designed and maintained permeable pavement systems can have a long service life, comparable to or even exceeding that of traditional pavement materials. This can result in cost savings over time through reduced need for repairs and replacements.

Versatility: Permeable pavement can be used in a variety of applications, including parking lots, driveways, walkways, and patios. It is available in various materials and designs to suit different aesthetic preferences and functional requirements.
Compliance: In many jurisdictions, the use of permeable pavement may help developers and property owners meet regulatory requirements related to stormwater management and environmental protection. This can streamline the permitting process and reduce the risk of fines or penalties for non-compliance.

Overall, permeable pavement offers a sustainable and effective solution for managing stormwater runoff, reducing pollution, and creating resilient, environmentally friendly urban landscapes.

Cost of permeable paving

The cost of permeable paving depends on what materials you use. You should call a professional to do the installation work as they have the knowledge and skills required for the job. For this, you can contact Natural Stone Carpets.
