Slab Paving in Lisburn

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.

To inexperienced people laying of paving slab isn’t much more than digging a little, purchasing little amount of mortar and pressing down the paving slabs. But how good would it have been if only it were that easy in real life? The truth is, in reality, laying paving slabs does not only require you to prepare your sub-base painstakingly and mix your mortar using the appropriate materials, but you’d also have to work with accurate and precise paver placements to guarantee the patio’s longevity. As a result, if you lack proper training or experience, we’d recommend you hire the services of a seasoned professional who can guarantee the best results and also save you time and extra cash that may result from possible costly errors. In this guide, you’d gain more insight into the paving slabs laying process.

To get started, you’ll need sharp sand, cement, shovel, wheelbarrow, pointing trowel, rubber mallet, spirit level, jointing compound, hard-bristled brush and tarpaulin.

• Mix a layer of mortar for each paver.

• Apply the mixed mortar onto the sub base by using the trowel.

• Slot the first flag in place and ensure not to stain the paver’s surface with the mixed mortar.

• Using a rubber mallet, carefully tap the paver to the mortar bed. Once done, ensure the surface is even with a spirit level.

• Take a measurement of the gap between the pavers

• Repeat the above steps until all pavers have been perfectly laid

• Leave the pavers to dry for about 1 to 2 days. You can protect it using a tarpaulin if concerned about rain.

• Use the jointing compound to fill up the paver gaps to bind together the pavers. Ensure to wipe off any excess compound using the hard bristled brush.

Slab paving is a great material to use to create a sturdy shed base.

Start by measuring out the area where your shed is going to be. This needs to be the size of your shed, plus about 10-20cm extra each way. Mark it out with string and pegs, make sure it’s square, and dig it down to about 6cm deep.

Then create a sand and cement mixture and put a layer down, followed by your paving slabs. Make sure you start in one corner and use a rubber mallet and spirit level to make sure they’re as level as possible. Leave this to set and you’re ready to use your shed base.
