Slab Paving in Cornwall

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.

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.

Do you know why paving slaps is a popular choice for both driveways and patios? Well, it’s the versatility! With its durability, diverse colour range, different styles as well as a timeless appeal, paving slabs happen to be a common choice amongst home owners. However, you should know that redeeming these benefits is not as simple as shovelling mortar and pressing down the paving slabs, and neither is it a case whereby you can just copy the laying process of a porcelain paving or block paving. Laying of paving slabs is on a whole other level! As a result, we’d recommend employing a trustworthy professional who can guarantee the best results the first time, especially if you lack proper training or experience to complete the task. In this step by step guide, you’ll discover more about the paving slabs laying process.

• Prepare your paving foundation. This includes checking that your foundation is level, marking out the area to be paved with wooden pegs, removing all vegetation and top soil to a depth of about 200mm to 250mm and raking the area level to ensure and even depth.

• Mix a layer of mortar for each paver and apply the mixed mortar onto the sub base by using the trowel.

• Lay the slabs on top of the laying course at the lowest point of the area to be paved.

• Take note that you may need to cut some slabs depending on the paving area size, your chosen slabs and the pattern selected.

• Once done, brush the area clean and start jointing. The best way to do this is by applying kiln dried sand to the paved area and carefully brush into the joints with a brush.

• Push the sands into the joints using a plate compactor

• Check the paved area for any gaps and fill where necessary.
