How To Cut Paving Slabs

You will almost always need to make cuts to some of your slabs when laying a patio.

Cutting slabs to fit around drain covers, steps or simply fitting the pavers to the edge of your available area are just a few examples of why you would need to, and we'll talk you through the two most widely used methods used for cutting paving slabs so you can get the best results!

How To Handcut Paving Slabs With A Hammer & Chisel

 
The original method of cutting slabs is to use a simple hammer and chisel.
This is best suited to Sandstone or Slate and is often recommended for Riven Paving or any slabs with a hand-cut edge. This will help to keep the look of the slabs consistent by matching your cuts with the existing hand-cut edges.
 

You will need:

• Tape Measure
• Pencil
• Hammer
• Breaker Chisel
• Rubber Mallet

 
1. Start by measuring the space you need to fill with your slab, then mark out the measurements onto the slab to use as a guide when cutting.
2. Using the hammer and chisel, cut a shallow channel into the slab down the markings around 1-2mm deep.
3. Now that the slab is scored, split the paver by striking the portion you want to cut off with the rubber mallet. Score the slab a little deeper if the paver doesn't split easily.
4. Tidy up any uneven edges using the hammer and chisel if necessary.
5. The slab is now ready to be laid.

Tips For Success

 
When measuring for your cuts, be sure to double-check that all of your measurements are accurate before you start and remember to account for joint widths. Being fully prepared and double-checking your measurements will always set you up for the best results and avoid any excessive, avoidable waste.
Ordering an additional 10-15% is always advised to cover you for waste during installation. Off-cuts will come from the total m² coverage that you have ordered and being prepared for this by allowing yourself an extra few slabs will prevent you from being left short of materials.
Overall, cutting paving slabs is a simple process and if you are unsure of anything, always consult a professional before going ahead.
