Pea gravel is a familiar sight to anyone strolling through a landscaped garden, where a sandy mixture of small, rounded stones crunches softly beneath your feet. Or perhaps when walking past a driveway paved with smooth, rainbow-hued pebbles you reflected on its striking resemblance to pea gravel. This relatively inexpensive, natural-looking material has established itself in homes, gardens and work sites throughout Australia for its utilitarian and aesthetic properties. Here's why:
What Is Pea Gravel?
Pea gravel is a naturally occurring aggregate composed of small, rounded stones. The size of the stones generally varies between 3 and 10mm. The rounded shape is achieved over millennia with the action of water eroding the edges of rocks on the beds of rivers, streams and natural deposits. The gravel is then collected and washed to remove any fine particles and sorted to remove any rubbish.
Pea gravel is not sharp and angular like crushed rock, so it feels easy to walk on and is easier to manipulate. However, it usually exhibits a range of natural colors from white, beige, and grey to brown to suit any style.
Key Benefits of Pea Gravel
- Affordable and Cost-Effective
A major benefit of pea gravel is its overall cost. For the most part, when compared to poured concrete, pavers or natural stone, pea gravel is much more affordable in both initial buy and installation costs. Less time, labour and machinery is needed to lay pea gravel which means less expense on the part of the property owner or designer.
- Excellent Drainage
The loose rounded shape of pea gravel helps promote percolation of water rather than piles of water resting on its surface. This is naturally perfect for if you have areas that receive a lot of water run-off as it minimises the occurrence of puddles forming after rain and erosion occurring. That's why it's often used on driveways and in flower beds and pathways.
- Low Maintenance
Pea gravel is very low-maintenance after installation. There’s no mowing like a lawn or topping up like with mulch. It’s also very durable, with years of use without needing maintenance. Raking it to move stones around and replacing it in the busiest areas is the most you’ll need to do.
- Versatile and Aesthetically Pleasing
Thanks to its natural colours and gently rounded, easy on the eye texture pea gravel suits myriad landscaping styles. From simple, clean lines of a modernist garden to rustic cottage schemes, it fits a variety of design approaches. It can also be incorporated with pavers, timbers and other landscaping materials to add variety.
- Durable and Weather-Resistant
Pea gravel can withstand the elements. Unlike other landscaping materials, it will neither crack, fade or degrade and can endure fierce Australian summers and cold, damp winters.
- Eco-Friendly Option
Due to the fact that it is a substance that enables the water to permeate naturally into the ground, the safety of the healthy soil helps to reduce the risk of storm water runoff. A rare natural element, simple to maintain, a load of pea gravels can last for numerous years.
Best Applications for Pea Gravel
Garden Paths and Walkways
Pea gravel is a popular material for informal gardenwalks. The sound that the loose stones make when walked over can be a pleasure to hear. Its drainage also means that it does not turn into a mud bath when it rains.
Driveways
Pea gravel drives are a cheaper option than concrete or tarmac. These provide excellent drainage and a more natural appearance. If a sound foundation and edge restraint is laid, it is possible to drive over the gravel surface on a regular basis, and still be shallow and speedy to maintain.
Garden Beds and Mulching
Pea gravel as a mulch alternative will aid in weed suppression, moisture retention, and provides an attractive finish around plants, trees, and shrubs. Unlike other organic mulches, pea gravel will not decompose, limiting replacement practice.
Playgrounds and Play Areas
Pea gravel has a rounded, smooth texture, which makes it a more child-friendly alternative to sharp-edged aggregates as a surfacing material under play equipment. Its granular nature cushions impact and allows for good drainage.
Pool Surrounds and Water Features
The natural appearance of pea gravel complements pools, ponds and water features. Its good drainage qualities helps to avoid standing water and the potential slip hazard around the edge of the pool and makes for a clean practical environment.
Drainage Solutions
In addition to its attractive appearance, pea gravel is commonly employed in French drains and trench drains as well as around downpipes to help disperse water off-site and help with site-wide drainage.
Decorative Landscaping Features
Used in places ranging from rock gardens, to dry creek beds,. Pea gravel is just one of many exciting materials that provide texture and visual contrast to garden designs often combined with larger feature stones, plants or timber pieces.
Tips for Installing Pea Gravel
Preparing the base: Clear trees and vegetation and level off before laying a compacted base. This will help stop the gravel sinking into the soil.
Use edging: Edging made from timber, steel or plastic will be useful in keeping the gravel in its place and stop any gravel from falling onto the lawns or footpaths.
Place a weed barrier: Use landscape fabric underneath the gravel to prevent weeds from sprouting. It will also keep the gravel from coming into contact with the base layer.
Use the proper depth: anything between 30-50mm of depth is fine for pathways and garden beds. Driveways may need to have a more substantial foundation of a deeper layer.
Replenish occasionally: Different areas of gravel will sink lower or move around, especially in busy areas, so topping up at intervals will help maintain a consistent, attractive finish.
