Cutting paving slabs with a chisel and hammer is a time-honoured way of getting the job done. It’s arguably the simplest and most fuss-free method, and requires the fewest tools. It’s also one of the safest techniques when it comes to cutting garden paving – so if you’re not confident using power tools, this might be the best option for you.

Get the measure of things

Your first step is to measure out the space you want to fill with your paver and then use chalk or pencil to clearly mark the required size on your slab. Use a spirit level to ensure straight lines and a neat finish.

Making the cut

Use the hammer and chisel to cut the pavers. Hold the chisel just outside of the line you’ve drawn on the slab and tap gently but firmly with the hammer until the brick splits. The chisel will then come in handy to knock off any sharp, uneven edges and help you create a neat finish.

The finishing touch

When you’re happy with the straight, even edges to your newly sized paver, slot it into its allotted space and ensure it’s firmly in place by tapping it with a rubber hammer.

Quick guide: Cutting paving slabs with a hand-held saw

Cutting through paving slabs needn’t be daunting – especially if you have the tools for the job. Here’s how to cut paving slabs with a hand-held circular saw:

  1. Set up your work stand
  2. Measure the paver length
  3. Cut the paver with the saw
  4. Slot in the paver

What tools do I need?

  • Skill saw or Stihl saw (must be a diamond-tipped blade)
  • Work stand with adjustable sides
  • Rubber hammer
  • Safety glasses
  • Protective gloves
  • Measuring tape
  • Pencil or chalk

What materials do I need?

  • Water in a bucket

In detail: Cutting paving slabs

Whether you’re laying your patio on concrete or any other material, a circular saw will help you get the job done in no time. But be sure to use a diamond masonry blade, rather than the standard blade used for cutting wood, which obviously won’t be strong enough to saw through paving slabs.

Setting the scene

Set up your work stand and ensure the sides are adjusted to the length of the paver you’ll be working with.

Measure it up

Using a tape measure, take the measurements of the space where you’ll need to install the paver and then, with chalk or pencil, mark up lines on the paving slab where it needs to be cut.

Top tip: Dip the paver in a little water to reduce dust levels – it will ensure greater accuracy when you’re cutting the paver.

A cut above

Secure the paving slab in the work stand and cut through the paver with the saw, using your chalk or pencil lines as a guide. Depending on its thickness, you might have to lift the blade and only cut through a little of the paver, then turn it over and repeat.

Use your judgement as to whether you’ll need to lower the blade more than once and simply keep lowering and cutting until you have a clean break.

In its place

Lay the paver in the space it’s required and tap it firmly in place with a rubber hammer.

Quick guide: Cutting paving slabs with block and slab splitters

These handy tools are simple to use, can cut through a variety of materials and they don’t produce much dust. Here’s how to cut paving slabs with block and slab splitters:

  1. Set up the block splitter
  2. Measure the paver length
  3. Cut the paver
  4. Slot in your paver

 

What tools do I need?

  • Block splitter
  • Rubber hammer
  • Safety glasses
  • Protective gloves
  • Measuring tape
  • Pencil or chalk

Also known as a guillotine or block cutter, the block and slab splitter is quicker than a saw. This means it’s often the preferred method of getting the job done. However, if you’re hiring one to use yourself, you will need to practice as it requires a level of skill. It’s worth investing the time though, especially as this method produces very little dust.

Set it up

Choose a location where the ground is level and stable to set up your block splitter. Make sure you have plenty of room around you.

Off the mark

Use a tape measure to assess the size of the space where you’ll need to install the paver. Using chalk or pencil, mark lines on the slab where it needs to be cut.

Making the cut

Raise the handle of the splitter and insert your paving block, positioning it so that the blade hits the block at the right position. Lower the handle until the blade has sliced right through the brick.

Lay in place

As with the other methods, once the paver is cut it’s time to place it in the space and tap it firmly with a rubber hammer until it’s level.

How to cut garden paving – the curved way

Cutting paving slabs is a relatively easy way to achieve a clean, straight garden paving design. It becomes a little trickier if you’re after a curved effect for your new-look garden.

A curved edge or circle can bring a new dimension to your outdoor space, but you’ll need to cut your pavers at an angle to get the look. While you can use a chisel and mallet to do this, you may find you get a more precise cut with power tools.

Using a circular saw. Mark up the paver as outlined in all the above methods and set it up on supports, ensuring the marked-up area is over the space between the stands.

Use a masonry blade to cut along your marked line – it may take a couple of attempts depending on the thickness of the brick. Practice is needed to create the perfect curve. However, if you find your cutting leaves burrs or uneven edging, you can file it down with a coarse metal file or use a grinding wheel to grind it off. This should then give you curved pavers that fit in perfectly with your garden paving design.
