How to make my own concrete paving block moulds

Updated February 21, 2017

If you have a very large paving job to complete, you should purchase pre-made pavers. However, if you have a small job to complete, you can build paving stone moulds and make your own pavers. This can save you money and prevent an excess of leftover pavers due to buying a pallet. Paver moulds are relatively easy to make and you can make them in just about any size you want.

Determine the dimensions you want for your paving stones. Go to a DIY centre and look at the stones they have for sale to get ideas. For this example, we will assume stone dimensions of 15 x 15 x 5 cm (6 x 6 x 2 inches). This is a common paving stone size. You can adjust these dimensions for your own needs.

Cut two wooden strips 15 cm (6 inches) long by 5 cm (2 inches) wide using a table saw. Use 2.5 cm (1 inch) thick wood.

Cut two wooden strips 17.5 cm (7 inches) long by 5 cm (2 inches) wide with a table saw. Use 2.5 cm (1 inch) thick wood.

Create a square by placing the two 17.5 cm (7 inch) strips parallel to each other. Place the 15 cm (6 inch) strips between the 17.5 cm (7 inch) strips and secure all four corners with a 3mm (1/4 inch) wood screws. When completed, the inside dimensions of the box is 15 cm x 15 cm (6 inches x 6 inches).

Spray the inside of the mould with lacquer and allow the lacquer adequate time to dry before moving on. The lacquer will prevent the block from sticking inside the mould.

Tip

To make the blocks, place the mould onto a flat bed of sand. Mix mortar in a bucket and then pour the mould full of mortar. Level the mortar in the mould with a trowel and give adequate drying time before lifting the mould off the block.
