Find a Driveway Installer you can trust in Kelty.

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.

Driveway surfacing materials like concrete, asphalt and clay brick usually crack because they’ve been exposed to extreme temperatures or put under high pressure. It’s important to repair driveway cracks before they get worse and cause damage to vehicles and perhaps others to trip on raised cracks.

Creating a tarmac path or driveway is a tricky process. It’s a job best left to professionals who know what they’re doing, as there are plenty of opportunities for it go wrong. However, even if you’re planning to hire someone to do it for you, it’s worth knowing how it’s done.

Firstly, you’ll need to remove any existing path or driveway and excavate down to formation level – about 175mm below paving level. Then, a membrane is laid down to prevent weed growth.

Next, a sub-base goes down, usually made of crushed rock or concrete. This is compacted and the tarmac is laid over the top. This is put down in two layers, and is rolled to make it compact and smooth.

It’s important to use edging when laying tarmac, to ensure that it doesn’t run off where you want your path or driveway to be. Tarmac paving and driveways also needs suitable drainage.

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.

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.

The best way to clean resin bound driveways is to sweep it regularly with a stiff broom. This will remove any debris and prevent moss from growing. It's a good idea to jet wash it after sweeping, because this will get rid of any smaller parts that a broom might not collect.

When you jet wash or power wash your resin bound driveway, make sure the pressure isn’t too high. It’s recommended to keep the pressure less than 150bar, as anything too strong could damage the surface. Make sure the water is cool, but not cold – both hot and cold water can damage the resin. Make sure the jet wash nozzle is at least 20cm from the surface. Any closer and this could damage your driveway. Use a sweeping back and forth motion to clean.

If you treat the area before you have your resin bound driveway installed, you shouldn’t get any weed growth. But if you get any moss or algae appear, you can apply a moss and algae killer that should remove and prevent any regrowth. If you have ingrained algae, you can remove it with a strong bleach solution; make sure you follow the manufacturer’s instructions. This should also help restore the driveway’s original colour. Make sure you rinse your driveway thoroughly with clean water after using bleach on it to prevent any harm to wildlife or plants.

If you get chewing gum on your resin bound driveway and you can’t get it off with a pressure washer, try using a freezing spray on it first. Then use a wall scraper to gently remove it – never dig under the chewing gum as this could damage the resin on your driveway.

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.

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.
