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.

While many professionals will recommend a pressure washer to clean block paving, it’s possible to clean your paving without one – just scrub the affected areas with a firm bristled brush and use plenty of soap. Then, rinse off the area with clean water.

No, pattern imprinted concrete shouldn’t be slippery. Most good driveway installers will add a special anti-slip agent to the sealant before they brush it onto your driveway, so it will stop it from being slippery.

It’s important to ask a driveway company how they will seal your driveway when you get a quote from them. If an untrustworthy company seals your driveway badly, it can cause a thick and extremely slippery surface, so it’s vital that you ask any contractor what their procedure is before you engage them.

It’s also important to remember that pattern imprinted concrete isn’t a ‘non-slip’ surface – it’s just not slippery. You could still slip over on a concrete driveway, just like you could on tarmac or a block paved driveway. Also, once you’ve walked and driven over your driveway for a few months, its skid and slip resistance will increase as it weathers and builds up tiny specs of dirt on it. Pattern imprinted concrete is often used in high footfall areas in places like shops, fast food restaurants and theme parks, so if there was a significant slip risk these businesses wouldn’t use it.

You might think that you could ask your contractor not to seal the driveway to make it less slippery, but it could actually do the opposite. By sealing pattern imprinted concrete, it means that moss and algae is much less likely to grow, which can be extremely slippery to walk on if it’s left to its own devices. If moss does form on your driveway, the sealed surface is much easier to clean as you can simply pressure wash it away; this is not as easy to do on a non-sealed surface.

Tarmac is a material made up of broken stone and tar, used for surfacing roads, driveways and other outdoor areas. It’s actually a registered product trademark, but many people use ‘tarmac’ interchangeably with ‘asphalt’. Asphalt is similar to tarmac, but is now more commonly used, and is made from bitumen instead of tar.

If your concrete driveway’s looking grubby, it’s best to try cleaning it with water and a brush, or a mild detergent. However, if this doesn’t work, it can be worth trying bleach.

Dilute your bleach down to 50% bleach and 50% water, and apply it to your driveway. Leave it for 10 minutes, then scrub it using gloves and a stiff brush. Finish by rinsing your driveway off with clean water.

It’s important to remember that bleach can stain certain surfaces and kill plants. So, if you’re concerned about materials and boarders around your driveway, it might be best to use a different type of detergent, like floor cleaner or degreaser.

Paving can be used for driveways and is capable of bearing the weight of cars and other vehicles. Ensure that you choose the appropriate type of paving, as some are designed for paths or decorative use. Correct installation is vital as improperly installed paving may move or break under the weight of a car.

Some paving projects require you to cut paving slabs to make them fit into a smaller space. To do this, firstly you need to measure the slab and draw a line in pencil or chalk where you want to cut.

There are then several different ways you can cut the slab – you or your professional can choose the one you or they are most happy with. A hammer and chisel can work well, or a handheld saw. You can also use an angle grinder fitted with a stone-cutting disc.
