Find a Driveway Installer you can trust in Ware.

Driveways usually sink because they haven’t been laid properly. They may not have been dug deep enough, or the installer might not have used the right materials. This will need to be corrected at the earliest opportunity, although in extreme cases, the driveway may need to be completly be relaid.

Oil stains on your concrete driveway can look obvious and unsightly. However, there are several different ways to remove them.

If you’ve only just spilled the oil, you can use a mixture of absorbent material, like sawdust, and solvent, like acetone or lacquer. Combine these, place them on the stain, cover and leave for about 24 hours. Then sweep up the mixture and rinse the area with water.

If you’ve got a small, older stain, you can use a detergent like baking soda, vinegar, washing up liquid or laundry detergent. Cover the stain with the detergent and leave for about 30 minutes. Then, add hot water and scrub the area and rinse. You might need to repeat this if necessary.

If it’s a larger, more stubborn stain, you might need to use a special degreaser. You can use this similarly to a detergent but make sure you follow the instruction on the bottle carefully.

Gravel is the cheapest driveway surfacing material. Asphalt costs a little more than gravel, and concrete is significantly more expensive. The cost of paving depends on the material you use. Obtain as many quotes as possible as materials and costs differ from company to company.

Cleaning block paving is a fairly straightforward task, although you’ll want to be careful to not use any chemicals that may cause damage to the surface. Use a simple household soap, mixed with water, and brush this across the paving with a stiff brush. Then, simply rinse off with clean water. Alternatively, use a pressure washer – but be careful not to use it on a powerful setting, as this may damage the joints and can cause slabs to come loose. Using the pressure washer on a medium setting and at a 45 degree angle is recommended.

Moss growth on tarmac and asphalt is pretty common. This can make your driveway or outside area slippy and untidy, so it’s a good idea to get rid of it.

Start by using a stiff brush to dislodge as much moss as possible and clear it off your driveway. Then use a moss killer to kill any remaining moss. Make sure you follow the product instructions – some moss killers are best used on tarmac or asphalt that’s clean and damp, whilst others are better for dry surfaces.

To prevent further moss growth, it’s a good idea to reduce the amount of shade on your tarmac or asphalt as much as possible. This will help you keep it as warm and dry as possible, and reduce moss growth.

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.

A resin bound driveway is made from resin and aggregates that are mixed together to create a smooth, flat surface. They’re often called ‘stone carpets’ because they offer a decorative finish that is durable and requires very little maintenance. It has lots of little gaps that allow water to drain into the ground, which means that you won’t get pooling or flooding around your property.

You can choose from lots of different colours and types of aggregate (stones) so that your resin bound driveway complements your property. Most contractors recommend choosing a darker aggregate because they are more resistant to the sun, but if you choose a good UV-resistant resin you should be able to have a lighter stone that doesn’t get too bleached by the sun.

To lay a resin bound driveway, resin and aggregates are mixed in a forced action mixer to create a mixture that a tradesperson will then pour and trowel onto a prepared base. It will become smooth once it’s cured, and the stones will all be contained, so you won’t have to spend time sweeping gravel back onto your driveway. The only maintenance that’s needed is to wash it with soapy water every now and again and sweep away any debris. Just make sure you don’t use chemicals or oils, as this might damage the coating.

Can You Lay Block Paving On Top Of Concrete?

The replacement or improvement of your driveway is unarguably one of the most expensive projects you can undertake in the exterior of your home. When done by a true professional the results can be impressive and visually appealing, however you’d have to pay huge bucks to have this done. This is exactly the situation with block paving as it is not only time consuming, but also a lot more expensive when compared to other types of driveway.

A large chuck of this cost is associated with the removal of the existing driveway. So assuming your old driveway is concrete, can you simply pave over the existing concrete? If yes, will it save you money? The simple and short answer is yes. It’s in fact advisable to pave over concrete as this will not only add around 20% to your home’s value, but also make it look a lot more attractive and pleasing to the eye.

However, there are some problems associated with block paving over concrete. It may be better to remove the concrete in situations whereby the base is substandard. For instance, if the ground underneath the concrete is failing, there’ll most definitely be problems.

Also, there’ll be some issues with settling (not even the cracks). If your concrete is dropping little amounts every year, these can affect the blocks and ultimately lead to dropping of some sections of the block paving in such a way that they’ll no longer be on the same level as the other blocks. Giving a rise to the possibility of drainage issues, tripping hazard and lots more.

Other issues that may crop up can be triggered as a result of using the wrong size block height as well as totally ignoring or overlooking the undulations of the concrete.
