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.

Do you want to know the level of thickness a driveway concrete slab should be? Well, you are not alone! So many other home owners ask this question on a regular basis and reasonably so. In order to prevent cracks on your concrete over time, it’s crucial to ensure an even thickness across your driveway concrete. To determine the necessary thickness of your driveway concrete, there are some questions that must be answered. These includes:

• What’s the number of vehicles you expect to have on your driveway?

• Do you plan on parking heavy, industrial vehicles on it?

For a standard passenger vehicle driveway, you’d have a driveway spanning 8 to 9 feet in width as well as 15 to 18 feet for double width. The thickness for this type of driveway concrete is usually 4 inches of non-reinforced pavement. Ultimately, this enables you to park everyday family cars on it without having to worry about it cracking due to the car’s weight. Also in order to prevent cracks, it’s expected that the driveway should be sloped towards the street as this would make sure that there’s a run off of water especially for areas that experience lots of flooding. In addition, there’s also the need to install joints to prevent cracking. For the standard 4 inch thick driveway, these joints should be positioned about 10 feet apart.

Finally for parking heavy industrial vehicles, your concrete driveway is expected to be thicker in order to cope with the added weight. Typically, the concrete driveway will require a thickness of about 5 inches. The additional one inch may not sound much, but the fact is this can increase the load carrying capacity of the concrete driveway by up to 50 percent.

There’s no doubt that weeds coming through your block paving can be unsightly and annoying. But, it’s relatively easy to get rid of weeds that are growing in the joints between your block paving. To start, pull out the larger weeds, and then you can use a pressure washer or firm bristled brush to remove the smaller weeds and debris from the joints in your block paving. It’s best to then refill the joints with additional sand to ensure your block paving remains level. Regularly brushing your block paving and treating with weed killer will help to prevent the weeds from reoccurring.

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.

• Where in the country you live
• What colour you choose
• What pattern you choose
• Whether you choose a standard or a higher-quality 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.

Resin bound driveways are known to last a long time without the need for repairs, but sometimes accidents happen. You also need to make sure you regularly maintain your driveway by sweeping and power washing it to prevent damage. But if it does get damaged, how do you repair your resin bound driveway?

If you notice a crack in your resin bound driveway, it’s important to repair it as soon as possible. If you leave it to erode, you could end up with a difficult repair that will cost much more money.

To repair a crack, you’ll need to carefully chisel it open slightly so you can apply a primer then fill in the crack with a matching-coloured resin and aggregate mix. While there are variations in colour and size with all stone mixes, usually it’s easy to find a batch that matches almost perfectly. And once the crack has been repaired for a while, it will blend in seamlessly with the rest of your driveway.

To prevent cracking in your resin bound driveway, it’s best to tackle the issue at initial installation. Speak to your installer about whether it’s possible to add fibreglass mesh to the base. You should also ask your installer to add expansion trims as these will significantly reduce the risks of cracks.

So the best way to repair resin bound driveways is to prise open the crack and fill it in. It might seem simple, but getting the right colour match is something that should be left to the professionals, so get a few quotes to ensure you get the best finish.
