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.

Clearing snow from a gravel driveway can be tricky – you need to remove the snow without taking the gravel with it.

If the snow’s quite light and dry, try using a leaf blower. You might find that this is enough to get the snow out the way. If it isn’t, start by using a shovel. Use this to clear the top layer of snow off your driveway, leaving about an inch behind. Then, use a rake to remove most of the remaining snow. This won’t take away 100% of the snow or leave all of your gravel in place, but it’s still pretty effective. You can then lay salt to melt away the rest of the snow and stop it turning into ice.

Removing oil from block paving can be tricky, and a professional clean and re-point is often the best option. However, for small stains, especially recent ones, it’s worth attempting to clean it yourself. To do this, you can purchase oil remover or driveway cleaning solutions – although be careful, as some may stain or mark certain kinds of paving stones. In general, stay away from acid based cleaners.

1. Prepare the sub-baseThe driveway company will excavate, or dig, the existing surface down to a depth of around 200mm. They will remove any debris from the area may place it in a skip or arrange for it to be removed in another way. When they dig down to the sub-base of your previous driveway, they will assess how much hardcore they need and arrange for that to be delivered to the site. They will then spread the hardcore across the sub-base to create a level surface to pour the concrete on. Most good contractors will apply a gel to any walls and doors to protect them from concrete splashes. They will also add any gulley tops, manhole covers or shuttering that’s required.
2. Installation and imprintingNext, the tradespeople will have the concrete either poured from a large mixer vehicle or barrow it in from a mixer and pour onto the surface. They level it with rakes, then add a colour surface hardener in a colour of your choice. This will give the driveway its permanent colour. They will then wait until the concrete has hardened to the correct consistency for imprinting the pattern, then will use special tools and stencils to make the pattern that you asked for. They will then spread a colour powder called a release agent over the surface, and leave to dry for 1 to 2 days depending on the weather conditions.
3. CleaningWhen the contractors return, they will add crack control cuts into the concrete. This is important because concrete expands and contracts in the heat, so there needs to be some give to stop any larger cracks from forming. Then everything is power washed clean, and a chemical wash is also used on the concrete to ensure it’s completely dust-free. The installers will ensure all your walls and doors are clean, which will hopefully be an easy job if they used wall gel.
4. SealingThe final step is to seal the driveway. There needs to have been at least two dry days before the tradespeople can do it, so you might find it’s best to have your pattern imprinted driveway installed in the summer. The contractors will blow any debris away from the surface and dry any damp areas where necessary. They will then add an anti-slip agent to the sealant and brush it on. It’s best to not walk or drive onto your new concrete driveway for about 4 days after sealing to allow everything to set. But after that, you’re ready to use your new driveway!
