How to Install Grey Slate Stones in the Garden
Installing grey slate stones is easier than you might think. You don't need to be a professional landscaper to get it done right. Here's a simple step-by-step guide to help you lay them safely and neatly.
Option 1: Dry-Laid (on Soil or Gravel)
This method is ideal for stepping stones or informal garden paths.
Step-by-step:
1. Plan the layout
Lay the stones loosely on the ground and adjust spacing. Walk around to see how it feels.
2. Mark and dig
Use a spade to mark each stone's shape. Dig down about 5–8 cm (2–3 inches).
3. Add a base layer
Fill the hole with crushed gravel or compacted sand. This helps with drainage and keeps the stone stable.
4. Place the stone
Set the slate stone in the base. Tap it gently with a rubber mallet to level.
5. Check level and adjust
Step on the stone. If it wobbles, adjust the base until stable.
6. Backfill
Fill any gaps with soil, gravel, or ground cover plants.
Option 2: Mortar-Fixed (for patios or heavy use areas)
Step-by-step:
Prepare a concrete or compacted sand base
Mix a thin layer of mortar or tile adhesive
Lay each slate stone and tap it level
Let it set, then fill gaps with grout or mortar mix
Seal the surface if needed
This method is better for high-traffic paths, patios, or where a more permanent finish is needed.
Tips Before You Start
- Always wash the stones before laying
- For a natural look, mix stones from different pallets
- Leave 10–20 mm (0.4–0.8 inch) gaps if dry-laying
- Use a spirit level or simply step-test for balance
- For best results, install during dry weather

Tips Before You Buy
This is a natural stone product. Expect slight differences in color, texture, and thickness. That's what gives it character. We recommend sealing the slate if you're using it in very wet or heavily used areas-it helps protect the color and makes cleaning easier.
