We often hear about permeability in the world of landscaping. But what exactly is a permeable paver? Find out more from your landscape expert.

What is permeability?

Permeability is the ability of a material to allow water to seep through it. In the context of uni pavers, this means that the pavers are laid in such a way as to allow rainwater to flow between the joints of the pavers and penetrate the soil below.

What are the advantages of permeable pavers?

Rainwater management

Permeable pavers reduce rainwater runoff by allowing water to infiltrate into the ground, helping to prevent flooding and recharge water tables.

Reducing impervious surfaces

Unlike completely impermeable surfaces such as asphalt or concrete, permeable pavers allow water to pass through, reducing the amount of water that runs off into storm drains.

Erosion prevention

By reducing the volume and speed of surface runoff, permeable pavers can help prevent soil erosion.

Improving water quality

Permeable pavers filter pollutants from rainwater, improving the quality of the water that seeps into the ground.

What types of permeable paving stones are there?

Wide-joint pavers

These pavers are installed with wider joints filled with gravel or another permeable material that allows water to seep through.

Honeycomb pavers

These pavers have a honeycomb structure that allows water to flow through the open cells.

Porous paving stones

The pavers themselves are made of porous materials that allow water to seep directly through.

Are permeable pavers easy to maintain?

Even so, maintaining permeable interlocking paving stones is simple. To maintain its effectiveness, however, regular maintenance is essential:

• Joint cleaning : Remove debris and sediment from joints to prevent clogging.
• Reloading joints : Add permeable gravel or sand if necessary to maintain permeability.

Permeability in interlocking paving is a crucial feature for sustainable stormwater management. By allowing water to seep into the ground, permeable pavers help prevent flooding, reduce erosion and improve water quality, while providing a stable, aesthetically pleasing surface for walkways, patios and pedestrian spaces.
