Our Expert Guide to Granite Paving

Classic granite is a go-to choice for strong, stylish, yet subtle paving. Available in the form of spacious slabs and charming cobbles, each in a variety of shades, it provides an array of styling options for your patio, path or driveway. 

In this guide, we’ll outline granite’s many benefits, the types of granite available, the process of laying granite paving, plus cleaning and care tips so you can decide if it’s the right material for your outdoor space.

What is Granite Paving?

Granite is an igneous rock with a grainy texture. In fact, the name granite comes from ‘grain’, and the graininess of granite is what makes it so popular as a slip-resistant paving material. It’s also very weight-bearing, hence its use in driveways. 

Why Choose Granite Paving?

‘Granite is a very durable, naturally hardwearing yet very contemporary option for paving. Its natural characteristics mean it is often a choice for public realm projects within towns and cities, where the volume of vehicular or foot traffic is at its highest, but it is also a very popular option for residential gardens, paths, and driveways.

Granite is a very dense material and has an extremely low porosity, meaning absorption of moisture is minimal. This means granite is resistant to the elements, and very low maintenance is required, which is rare with natural products.

Its robustness, along with its natural charm and beauty, means it is not only a practical choice, but it is an aesthetically pleasing and durable option for paving anywhere.’

Types of Granite Paving

Like many of our natural paving stones, granite has variations in colour, allowing you to select the shade that best suits your garden aesthetic. Choose dark grey granite for a classic and dramatic paving style, or opt for light-coloured granite for an airier and softer look. 

What is Flamed Granite?

Flamed granite is specially heat-treated granite paving. This heat treatment makes the granite’s surface rougher, increasing slip resistance. This makes it a popular paving choice for yards where sports might be played or children may run about. 

How Large are Granite Slabs?

Granite pavers tend to be wide and long for a spacious, airy appearance. Ours is sold at 600x900x20mm. 

However, for smaller and more compact granite pavers, see our cobbles. These can be arranged for a neat yet quaint and rustic look, and are available in 100x100x30mm and 100x200x30mm size options. 

How to Lay Granite Slabs?

Here is our easy 11-step guide to laying granite slabs. 

1. Measure the area. Measure the length and width of your space to calculate the total square meterage needed for your project.
2. Create a dry layout. Before using mortar, arrange the granite slabs on the ground to visualise the pattern and make sure everything fits correctly.
3. Excavate the area. Dig down about 150mm (6 inches). This depth allows for a sub-base, mortar bed, and the paving slabs themselves.
4. Install the sub-base. Lay a weed-proof membrane over the excavated area. Cover it with 100mm of crushed stone, compacting it firmly in two layers using a wacker plate.
5. Mix the mortar. Combine 2 parts building sand, 2 parts grit sand, and 1 part cement with water in a cement mixer until it is a stiff but wet consistency that holds its shape.
6. Lay the first slab. Spread a 30-40mm layer of mortar for the first slab. Place the slab on top and tap it gently with a rubber mallet. Use a spirit level to ensure it has a slight slope (a minimum fall of 1:60) for drainage.
7. Continue laying. Repeat the process for all remaining slabs, making sure to maintain consistent spacing and level.
8. Make cuts. If needed, use a diamond blade on a saw to cut slabs to size, and always wear the proper safety gear, including a mask and goggles.
9. Allow the mortar to set. Let the paving rest for 24-48 hours so the mortar can cure properly.
10. Apply jointing compound. Wet the area and apply your chosen jointing compound to fill the gaps. Wipe away any excess and let it harden for another 24 hours.
11. Seal the surface. To protect the granite, especially if it has a textured, porous finish, apply two coats of a suitable sealer.

How to Clean Granite Paving

Granite is a low-maintenance paving material, and upkeep is minimal. Simply sweep away debris when needed and scrub with a soft-bristled brush and stone cleaner periodically.
