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.

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.

Gravel driveways, when properly installed, can be a very cost effective way of surfacing all driveways including both the big and the small ones. As a result, it has grown to become a common choice amongst homeowners in the UK. It does a great job at giving a property a more natural look than other driveway surfacing options which includes concrete, block paving or tarmac.

Are you planning to install a gravel on your driveway? If yes, then you’ll most likely be interested to know exactly how much it’s going to cost. Well, to get started you’ll have to decide whether you’ll be doing this yourself or perhaps you’d be hiring a specialist. The project could be much more effective if you decide to tackle it on your own as you’re only going to be worried about the paying for the materials without any labour costs. However, installing a driveway is in no way an easy task even for the competent and more experienced DIYers. So if you choose to carry out the project on your own, you should also get ready for a longer completion time than it would have been if you hired a tradesman which is usually around 48 hours. If you have all the tools and materials in place before commencement, then it’s possible to complete the project over the weekend. However, there are many risks involved such as the possibility of misjudging the amount of base layer and gravel required etc.

Here, we’ll look at the various material costs of gravel driveways, as labour costs largely varies from one tradesman to the other.

The material cost of a gravel driveway of about 20 square metre should range between £1100 to £1200, 40 square metre should cost between £1600 to £2000 and 80 square metre gravel driveway should cost between £2800 to £3200.

Being a strong and durable product requiring little maintenance and expected to last over 2 decades, it’s little wonder resin is now a popular material amongst homeowners in the UK to build their driveways. However, there’s always the issue of the driveway fading, cracking or even becoming worn and tired. So is it possible to repair resin driveways? The answer is yes, a resin driveway can be repaired, however the best approach to use largely depends on the issue being faced. As a confident DIYer it’ll be very easy to do, but if you lack the confidence then calling in a professional for help would be a better option. So let’s take a look at how you can repair your resin driveways.

For cracks, the best reparation approach would be to chisel it out. Once done, then you can proceed to breaking the stones to form a rough edge. It’s important to make sure that the matrix of the stone remains unaffected. Make a new mixture of resin bound stone and pack it in tightly to the gap. While doing this, we’ll recommend making use of a plastic trowel to avoid burnishing. This fresh mixture will then create a smooth and perfect surface by interlocking with the edges. You can follow similar procedure for patches but these are larger holes or damages than cracks and as the name suggests are mostly likely to remain noticeable but will prevent further crumbling of your resin driveway.

For homeowners, who aren’t so keen about the patch repairs, you can opt for an overlay especially in the event whereby the majority of the surface has failed. Although many usually shy away from this approach because of the perceived high expenses, but the fact is that the approach is actually cost effective as you won’t have the need to spend more money in the long run.

While resin bound and resin bonded driveways have similar names, it might surprise you to know that they’re very different. Both paving systems use resin and aggregates (stones) to form a fixed surface, but there are plenty more differences than there are similarities.

Resin bound driveways are made from a resin and aggregate mix that is trowelled onto a bitmac or concrete base. It leaves a smooth, flat finish and you won’t find any loose gravel. It’s also a pourous surface, which means that rainwater can pass through into the ground, avoiding pools and flooding.

However, resin bonded driveways involve spreading resin across a base, then scattering aggregate into it. Most of the stones will stick to the resin, but some will stay loose. That means you’ll get the effect of loose gravel without so much to sweep and take care of. Because the stones are scattered onto a complete layer of resin, water can’t pass through it. That means you could end up with water pooling, and it also means that a resin bonded driveway isn’t frost resistant, meaning it could get slippery.

So which is better – a resin bound or resin bonded driveway? The answer depends on a few things. If you have a period property where a smooth, shiny surface might not complement the look of your home, you might want to go for resin bonded. If you need lots of grip, for example if you’re a wheelchair user, resin bonded may also be the way to go – even though resin bound surfaces still offer enough grip for sloped driveways and ramps. But if you want a low-maintenance, weed-free, permeable surface, resin bound driveways are the way to go.

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.

From gravel and crushed stones to asphalt and tarmac, the choice when it comes to surfacing options for driveways is truly staggering. However, what’s not too clear is the options that best suits a sloping driveway. If you also possess a sloping driveway and wondering the best material to install, you’re definitely not alone. This is a major source of concern for several home and property owners in the UK being fully aware that making the wrong choice here can prove really costly and disastrous. In order to help you make the best informed decision possible, we’ve put together this post which takes a look at the various driveway material options available to you.

• Gravel
  This driveway surfacing option provides a truly enjoyable “crunch sound when driven on, however, the satisfaction will be short lived if installed on a sloped driveway. If installed on a sloped driveway, there’s going to be a continual displacement as instinctively rolls downhill on an incline.

• Concrete
  This can prove to be a great problem if installed on an incline. This is due to the fact that concrete is subject to freeze/thaw phenomenon which makes it steep and slippery lacking the needed traction.

• Tarmac
  This is particularly far from ideal when it comes to a steep driveway surface. This is because it requires continuous maintenance to prevent spillages from spoiling the surface.

• Resin
  The best surface for a steep driveway is simply that made from resin. This is due to the fact that this surfacing option allows water to soak away naturally. They’re perfectly permeable, preventing water from pooling and reducing the risk of falls.
