How To Lay Driveway Paving

A well-laid driveway not only improves the appearance of your home but also provides a durable surface that can withstand everyday vehicle traffic. Proper preparation is the key to preventing movement, sinking and drainage problems. Follow our step-by-step guide below, and don’t forget to browse our recommended products at the end of this article to help complete your project.

Tools & Materials You’ll Need

Step 1: Prepare the Base

Driveways experience much heavier loads than patios, so a strong foundation is essential.

Lay a compacted 150mm layer of MOT Type 1 hardcore across the entire driveway area. This provides the strength needed to support vehicle traffic and helps prevent future sinking or movement.

For areas with lighter foot traffic, a 75mm compacted sub-base is generally sufficient.

Using a plate compactor (wacker plate) is highly recommended to achieve a firm, stable base before continuing.

Step 2: Set Out the Driveway

Mark out the driveway using wooden pegs and a string line.

Position the pegs so they represent the finished height of the paving. Creating a grid of string lines across the area makes it easier to maintain accurate levels during installation.

If the driveway meets your property, ensure the finished paving level remains at least 150mm below the damp proof course (DPC) to prevent damp problems.

Step 3: Create the Correct Fall

A slight slope is essential to allow rainwater to drain away from the property.

As a guide, create a fall of approximately 1:60 away from buildings or towards suitable drainage points.

Use a spirit level and string lines throughout the installation to regularly check that the correct gradient is maintained.

Taking time to set the fall correctly will help prevent standing water on the finished driveway.

Step 4: Lay the Bedding Layer

Once the hardcore has been fully compacted, spread a full bed of mortar using approximately:

  • 4 Parts Sharp Sand
  • 1 Part Cement

Lay only enough mortar for a few paving slabs at a time to prevent it from drying before installation.

The mortar should be firm and workable rather than overly wet.

Step 5: Lay the Paving

Start laying the paving from one corner, placing each slab carefully onto the mortar bed. Use a rubber mallet to gently tap each slab into position while checking the level with a spirit level.

Leave consistent joints between each slab and regularly check the alignment using a straightedge or string line.

Continue laying the paving across the driveway, checking both the level and drainage fall as you work.

Once complete, allow the mortar to cure before applying the appropriate jointing compound or jointing material.
