Block Paving in Barnet

Is Block Paving Permeable?

Back in 2008, there was a regulation introduced which comes with a requirement guiding the pavement of front gardens. It requires homeowners to incorporate the conventional impermeable driveways which makes for an uncontrolled run off of rainwater into sewers, roadways, local watercourses etc. However since then, new systems have been established which complies with the legislation and permit driveway laying of block paving without requiring planning permission while still providing the same visually appealing features as the conventional systems. Therefore, a short and simple answer to whether block paving is permeable is yes.

A permeable paving driveway (unlike the conventional ones which quickly diverts rainwater towards the edges to local drains) purposefully diverts rainwater into the built paving structure which oversees a controlled release of the rainwater into the environment. Permeable block paving comes with a wide range of benefits which includes the following:

• No Planning Permission Required

Unlike the traditional system, permeable block paving requires no planning permission as it oversees the driveway draining by ensuring that the surface water passes directly through the joints which makes sure the drains are not over worked and minimizing the risk of flood.

• Puddles Reduction By Natural Drainage

A permeable block paving minimizes puddles as well as standing water which helps to boost natural drainage. This is due to the laying process which features little voids that permits the passage of water.

• Natural Filtration

A natural filtration occurs when water is allowed to return to the ground by permeable block paving which helps assists in getting rid of any pollutants from the rain water.

• Flood Prevention

Permeable paving can help to prevent flooding as it absorbs water rather than directing it to the local drains or leaving it to build up on the surface’s top.

• Natural & Sustainable Materials

Natural and recyclable materials can be incorporated in producing permeable paving which is an excellent choice especially if you’re seeking a more sustainable driveway.

Have you decided to install block paving and wondering what the best sand to be applied to the joints is in order to achieve a perfect job? Well, you’re at the right place! This is one of the most frequently asked questions when it comes to block paving and we seek to give you a reliable solution once and for all.

The best sand for block paving is a kiln-dried sand. It’s an extremely fine sand which has been dried in a kiln to get rid of all the water before it’s incorporated to achieve the best results. Therefore, the sand contains no moisture and is commonly used to fill the joints of block paving to keep the paving’s structure rigid and strong. It also goes a long way to prevent the ingress of water while stopping the paving from moving and becoming loose. The major reason why the paving sand must be dried is to allow it flow easily into the joints as well as the block paving’s gaps. As result of this smooth flowing to the bottom of the joints, there will be no sand sticking to the sides of the pavers.

Another major reason why kiln-dried sand is commonly applied to the block paving’s joints is to prevent water from penetrating the paved area. It also tightens the individual pavers together to prevent from moving and becoming loose. In the event whereby you happen to leave the joints of your block paving without kiln dried sand, it’s highly likely that they’ll sink as a result of water penetration and the blocks will become very loose. After washing block paving, it’s very important to also replace any sand washed off in the process once the paving is dried to prevent water ingress into the joints.

The most commonly used driveway surfacing materials are gravel, asphalt, concrete and paving - which can be block, slabbed or patten imprinted. Take a look at our product information pages to help you decide which one to use and which one will look best for your driveway.

Your contractor should have access to your driveway and a power source. If they have these things, you don’t need to be there while they’re working on your driveway. However, it’s worth being around if you can so you can clarify details and answer any questions.
