Aggregates FAQs

At MB Wilkes, we supply a wide range of decorative gravel, slate chippings, pebbles and garden stones to suit different outdoor projects.
Please read our ‘Ultimate Guide to Using Decorative Stones in Your Garden’ blog for more ideas and usage.

Slate chippings, decorative pebbles and limestone chippings are excellent choices for garden borders. Slate creates a modern appearance, while lighter stones such as Cotswold Chippings and Dorset Limestone Chippings provide a more traditional finish. MB Wilkes stocks a variety of decorative garden stones, including Black Slate, Plum Slate and Scottish Pebbles, helping you find the right colour and texture for your outdoor space.

The amount of decorative aggregate required depends on the area you want to cover and the depth of the stone. For most garden borders and pathways, a depth of approximately 40–50mm is a useful starting point, although larger stones may require a deeper layer. Measure the length and width of your space to calculate the area in square metres. The MB Wilkes team can help you estimate the quantity required based on your chosen aggregate.

For decorative garden borders, a depth of around 40–50mm is usually suitable for smaller stone chippings. Larger decorative aggregates, such as 40mm slate or cobbles, may require additional depth to achieve even coverage. The ideal depth depends on the aggregate size, ground conditions and intended use. Preparing the surface properly before laying your decorative stones will help achieve a long-lasting, attractive finish.

Yes, decorative aggregates are a popular low-maintenance garden alternative to traditional garden surfaces. When installed correctly, gravel, pebbles and slate chippings can help reduce exposed soil, limit weed growth and protect flowerbeds from erosion. They also provide a durable finish that requires relatively little upkeep. Occasional raking, removal of debris and topping up will help keep your decorative garden stones looking their best.

The best colour depends on your garden design and the appearance you want to achieve. Light-coloured stones, such as Cotswold Chippings and Polar White Chippings, create a bright, natural finish. Darker options, including Black Slate and Basalt Chippings, offer a modern, contrasting look. For additional colour, MB Wilkes also stocks decorative aggregates such as Devon Pink Chippings, Plum Slate and Spanish Gold Marble Chippings.

Decorative pebbles are a popular choice for creating attractive borders around ponds, fountains and water features. Smooth stones, such as Scottish Pebbles, can provide a natural finish and complement surrounding plants. However, if stones will be submerged, particularly in a fish pond, it is important to check that the chosen material is suitable for the water chemistry and aquatic life. MB Wilkes supplies a selection of decorative pebbles in different sizes and colours for landscaping projects.

Decorative gravel and garden stones are relatively easy to maintain. Remove fallen leaves and debris regularly, rake the surface to redistribute stones and carefully rinse them with clean water when required. For heavily soiled areas, a gentle wash may help restore their appearance. Avoid harsh cleaning chemicals, particularly near plants or water features. Regular maintenance will help preserve the natural colour and appearance of your decorative aggregates.
