Permeable paving is becoming an increasingly popular hard landscaping choice for homeowners across the UK. Whether you’re looking to create a new driveway, patio, or garden path, understanding the benefits of permeable paving can help you decide if it's the right fit for you.
In this guide, we explain permeable paving, its uses and types, which materials are permeable, and its benefits.
What is permeable paving?
Permeable paving is a type of hard landscaping that allows water to pass through its surface, filtering into the ground below. Unlike traditional paving, which can lead to water pooling and run-off when there’s no proper drainage applied, permeable paving is designed to manage water and prevent flooding and waterlogging.
Permeable paving is made from materials with gaps or spaces between them, allowing water to flow through. These materials can range from permeable concrete to more decorative options like resin-bound gravel and specially designed permeable pavers.
Where is permeable paving used?
Permeable paving is versatile, meaning it can be used in various settings around your property. Here are a few of the places which can benefit from permeable paving solutions:
- Driveways: One of the most popular uses for permeable paving is in driveways. It provides a durable surface that can handle the weight of vehicles whilst also managing rainwater effectively.
- Patios and garden paths: Permeable paving is also an excellent choice for patios and garden paths, offering practical water management, and thanks to the designs availabl and aesthetic appeal that can complement your property.
- Parking areas: Permeable paving is ideal for homes with larger parking areas, preventing water build-up and ensuring your parking space remains safe and functional year-round.
- Front gardens: Many homeowners now opt for permeable paving in their front gardens, especially in areas where planning regulations encourage or require sustainable drainage solutions.
What are the different types of permeable paving?
Permeable paving can be made from a variety of materials, each of which offers some key benefits. Different materials are better suited to different uses. Here are some common options and their advantages:
1. Permeable block paving
Permeable block paving is one of the most popular choices for domestic projects. It looks similar to traditional block paving but is designed with wider joints filled with a permeable material like aggregates or a special jointing compound. Their unique design allows water to drain through the gaps between the blocks, preventing surface water build-up. The advantages of permeable block paving are as follows:
- Aesthetically similar to traditional block paving
- Available in many colours and finishes to suit any style
- Excellent water drainage capabilities
- Durable and long-lasting
- 100% recyclable
2. Porous asphalt
Porous asphalt is often used for driveways and larger areas where high water permeability is needed. It’s made from a special mix of asphalt that includes larger aggregates, creating voids that allow water to pass through. Here are some advantages of porous asphalt:
- Cost-effective for large areas
- Excellent water drainage capabilities
- Low maintenance and long-lasting
3. Permeable resin-bound gravel
Resin-bound gravel is a decorative and functional option that’s become increasingly popular recently. It is created by mixing aggregate stones with a clear resin and then laying this mixture onto a prepared surface. The result is a smooth, permeable surface that allows water to drain through the gaps between the stones. Some advantages of permeable resin-bound gravel include:
- Visually appealing and available in a range of colours and textures
- Smooth, accessible surface ideal for walking and driving
- Low maintenance and weed resistance
4. Grass pavers
Grass pavers, or grid pavers, are a green solution that combines hard paving with grass. These pavers are made from plastic or concrete grids filled with soil and grass, providing a stable surface for light traffic and allowing water to drain. Grass pavers are:
- An eco-friendly solution
- Blends seamlessly with green spaces for a natural look
- Supports the growth of grass, contributing to local biodiversity
What materials are permeable?
It’s important to understand the permeability of different options when deciding which material to use for your project. Here, we’ll explore some common choices and questions, explaining whether they are permeable.
Is tarmac permeable?
Traditional tarmac is not permeable; it creates a solid, impermeable surface that can lead to water pooling and run-off.
Is block paving permeable?
Not all block paving is permeable, but specific designs, such as Marshalls' Driveline Priora, are engineered to be permeable. These blocks are laid with gaps filled with permeable jointing materials, allowing water to drain through the surface.
Is sandstone permeable?
Sandstone is a naturally porous material, meaning it can absorb some water. However, when used in paving, it is not typically considered fully permeable, as the gaps between the stones are often filled with mortar to make for a sturdy install, which prevents water from passing through.
Is concrete permeable?
Standard concrete is impermeable, meaning it does not allow water to pass through. However, permeable concrete, also known as pervious or porous concrete, is designed with larger aggregates and less sand, creating voids that allow water to seep through.
Is MOT Type 1 permeable?
MOT Type 1, a crushed aggregate material commonly used as a sub-base in driveways, is not permeable. It compacts to form a solid layer that does not allow water to pass through, making it more suitable for traditional, impermeable paving systems.
Are gravel driveways permeable?
Yes, gravel driveways are naturally permeable, allowing water to drain through the spaces between the stones. This makes gravel an affordable and effective option for a permeable driveway.
Are bricks permeable?
Standard bricks are not permeable. However, permeable paving systems can incorporate bricks with wider joints or gaps filled with permeable material, allowing water to drain through the surface.
Is slate permeable?
Slate is a dense, non-porous material, so it is not considered permeable. However, when used in paving, slate creates an impermeable surface that requires proper drainage solutions to manage water runoff.
What are the benefits of using permeable paving?
There are numerous benefits to using permeable paving in your landscaping projects. Here’s why you should consider it:
1. Improved drainage and flood prevention
Permeable paving’s main advantage is its ability to manage water more effectively than traditional paving. Allowing water to soak through the surface reduces the risk of flooding and waterlogging in your garden or driveway. This is particularly important in areas prone to heavy rainfall or with existing drainage issues.
2. Environmental benefits
Permeable paving helps to reduce the amount of pollutants working their way into local water sources. Filtering water through the ground naturally cleanses it, contributing to healthier local ecosystems.

3. Compliance with planning regulations
In many areas, local councils have introduced planning regulations that require new driveways and paved areas to be permeable. This is part of a broader effort to manage urban drainage and reduce flooding risks. By choosing permeable paving, you can ensure that your project complies with these regulations, potentially avoiding costly planning delays or fines.
4. Low maintenance
Permeable paving systems are generally low maintenance, requiring less upkeep than traditional paving. Because they are designed to allow water to drain away, you’re less likely to experience issues with standing water, moss, or algae. This can reduce the need for regular cleaning and maintenance, saving you time and money in the long term.
5. Enhanced aesthetic appeal
With a wide variety of styles, colours, and materials available, permeable paving can enhance the appearance of your home. Whether you prefer the classic look of aged cobblestone or a more natural aesthetic, there’s a permeable solution for all types of gardens.
6. Long-lasting durability
Permeable paving is designed to be durable and long-lasting, even in areas with heavy foot/vehicle traffic. Materials like resin-bound gravel and permeable blocks are resistant to cracking and can withstand the freeze-thaw cycles of the British climate, making them a smart investment for any home.
