17 Jun 2023
Laying paving stones is a rewarding do-it-yourself project that can completely transform your outdoor space. Proper installation is critical for long-lasting results when building a new patio, pathway, or driveway. We’ll walk you through the step-by-step process of laying paving blocks in this guide to help you achieve a professional-looking finish.
Step 1 – Preparation and Planning
Proper planning and preparation are required before you begin laying paving stones.
- Begin by measuring and marking the area where the blocks will be installed. Remove any vegetation, debris, or existing paving from the site.
- Examine the condition of the ground and make any necessary repairs or adjustments.
- Make sure the area is well-drained to avoid water accumulation.
- Gather all of the project’s tools and materials, including paving blocks, sand, a shovel, a rubber mallet, a spirit level, and safety equipment.
Step 2 – Laying a Firm Foundation
A solid foundation is essential for a successful paving block installation.
- Dig out the marked area to a depth of 8-10 inches, with a slight slope away from any nearby structures to allow for proper water drainage.
- Remove any soft or unstable soil, then compact the remainder with a plate compactor or a hand tamper.
- Then, as a sub-base, add a layer of hardcore or crushed stone and compact it thoroughly.
- Spread a layer of sharp sand over the base and compact it with a rake or a piece of wood to further stabilize it.
Step 3 – Laying the Paving Blocks
- Begin by laying the first paving block in one corner of the area, making sure it is level and aligned with the desired pattern.
- Check the horizontal and vertical positions with a spirit level.
- Place a wooden block on top of the paving block and gently tap it into the sand with a rubber mallet.
- Place the blocks one at a time, leaving a small gap (about 1/4 inch) between each one for jointing sand.
- Check for levelness and alignment on a regular basis, making adjustments as needed.
Step 4 – Final Details
- Spread jointing sand over the surface once all of the paving blocks have been installed.
- Brush the sand into the gaps between the blocks with a broom to ensure it fills all of the spaces.
- Gently compress the blocks with the plate compactor or by tapping them with the rubber mallet.
- Continue adding sand and compacting until the gaps are completely filled and the blocks are secure.
- Finally, sweep away any excess sand and rinse the area with water to further settle the sand.
Step 5 – Maintaining and Repairing Paving Blocks
Regular maintenance is required to ensure the longevity of your paved area.
- Inspect the blocks on a regular basis for signs of damage or movement.
- Remove any loose or damaged blocks, replace the bedding sand if necessary, and reposition them.
- Keep the surface clean by sweeping it on a regular basis and removing any weeds or debris that may accumulate.

Remember to take your time, pay attention to detail, and ensure proper alignment and levelness throughout the process, followed by regular maintenance.
