Are tarmac driveways permeable and what are its benefits? This article will explore permeable tarmacadam, Porous paving blocks, gravel, and resin. It will also explain what permeable paving blocks are and why they are a better choice than normal paving. Read on to find out more. Ultimately, you should consider the materials you choose based on your needs and budget.

Permeable tarmacadam

A permeable tarmac driveway allows rainwater to pass through and soak into the soil below. The porous surface is essential to allow water to pass, and to ensure this does not happen, it should be regularly maintained. Choosing permeable paving materials for your driveway can save you money on the cost of a new one, and it will benefit the environment too. Permeable surfaces prevent water from filling up water systems, reducing pollution and saving money on your utility bills. Rainwater is also a major contributor to pollution in water systems, picking up debris, oil, fertilizer, and garbage from roads and driveways. This pollution clogs up water treatment facilities and costs money.

If you want a permeable driveway, you’ll need to ensure you have a proper base, which should consist of a solid substrate and loose aggregate. The manufacturer should provide the exact specifications for the base, including the requirements for this material. New regulations in the UK call for permeable paving, but don’t fret if you don’t – you can still lay a non-permeable driveway. However, you’ll need to make sure you have some way of disposing of any excess water.

Porous paving blocks

If you’re looking for a durable, attractive way to create a tarmac driveway that can be cleaned easily, you should consider porous paving blocks. These concrete paving stones can be laid in a wide variety of designs. Porous concrete paving stones are typically laid 50mm thick and have an open-graded design. Porous paving stones are suitable for areas where water may become trapped, such as in the parking area of a retail complex.

Porous paving is often installed on tarmac driveways for its versatility. These blocks have many benefits, including a lower price than their impervious counterparts. Unlike other types of paving materials, porous pavements can last decades and still function properly. The pores in the pervious paving blocks allow water to expand without causing damage to the pavement. The benefits of porous pavement are not only a low maintenance choice, but they can also be a good choice for areas where water levels are high and seasonal temperatures fluctuate.


Permeable driveways allow water to seep through them and soak into the ground below. They must have gaps and pores to do this, but you should check zoning laws before you start paving your driveway. Make sure you regularly mow your driveway to prevent any clogging. Gravel driveways are a great option if you want to reduce your home’s carbon footprint. And remember, permeable driveways are less expensive than paved driveways.

While gravel driveways have many benefits, they are not for everyone. For one thing, they require regular maintenance, including top dressing. This makes snow removal tricky. Additionally, heavy vehicles may cause rutting in your gravel driveway. And, unless your driveway is supported by pavers, you cannot leave your car parked in it all day. This would destroy the grass and cause further damage. Lastly, gravel driveways do not support heavy vehicles, which means that they may be inefficient in storing water.


Resin makes tarmac driveways permable by allowing water to soak through the surface. Unlike other materials, such as tar, resin allows water to pass through. Permeable driveways are a great option for people who live in areas where flooding is common. They are also an excellent way to improve the appearance of your home and increase its value. If you are thinking of installing a resin driveway on your property, it is essential to choose an experienced installer who can give you advice on the best solution.

When you choose a resin driveway, you’ll be reducing your carbon footprint. It requires minimal maintenance and won’t stain easily. Furthermore, you can have the colour and logo of your choice imprinted on the surface. While tarmac driveways are more affordable, resin cannot compete with the endless colour options that resin driveways have. They are also the perfect choice for businesses who want to make a statement about their company.
