Pea gravel is a small, rounded stone commonly used in landscaping and construction due to its smooth texture and attractive appearance.
 
What is Pea Gravel Made From?
Pea gravel is:
Natural stone, often formed from river rock.
Typically made of quartz, granite, limestone, or basalt.
Stones are rounded and smooth, ranging in size from about 12mm.
 
What is Pea Gravel Ideal For?
Pea gravel is ideal for:
Garden paths and walkways – comfortable underfoot
Driveways – provides good drainage and a rustic look
Playgrounds – soft and safe for children (but can shift)
Around fire pits or seating areas
Decorative garden mulch – helps retain moisture and suppress weeds
Base layer for patios or pavers – supports drainage
 
Recommended Thickness for Pea Gravel Layers
Walkways & patios:
🔹 5–7.5 cm (2–3 inches)
Driveways:
🔹 10–15 cm (4–6 inches) or more, depending on traffic and base layer
It's often best to install over a compacted base (like crushed rock) and use landscape edging to keep it contained.
 
How to Maintain Pea Gravel Surfaces
Rake regularly – to redistribute displaced gravel and keep the surface level.
Top up occasionally – stones can sink into the ground or migrate over time.
Weed control – use weed barrier fabric underneath, and remove weeds as needed.
Re-edge or contain – install edging (metal, plastic, stone) to prevent spread.
Compaction – optional, but lightly compacting can stabilise it for paths.
