Frequently Asked Questions

What is the difference between pebbles and gravel?

Pebbles are naturally rounded stones, typically used for decorative purposes, water features, and Japanese-style gardens. Gravel is angular or semi-angular crushed stone, better for driveways, paths, and drainage as it locks together under load.

Which pebbles are best for a garden border?

For borders, smooth rounded pebbles in the 20–50mm range work well. Popular choices include Snow-White Thassos Marble (bright, luxurious), Black Basalt (modern, bold), and Silver Granite (classic, neutral). Choose a colour that complements your planting.

Can I compare pebbles from different UK suppliers?

Yes — that's exactly what our comparison tool is for. Paste a product URL from Wickes, B&Q, Decorative Aggregates, Stone Warehouse, or any other UK supplier and compare it against Stones4Gardens products side by side.

How do I know which size pebble to choose?

For pot toppings and fine borders, use 8–20mm. For general garden borders and decorative beds, 20–50mm is most popular. For driveways and paths, angular gravel at 14–20mm grips well. Water features look best with 30–60mm smooth pebbles.

What is the cheapest garden stone option?

Pea gravel at £80–£150 per tonne is the most affordable decorative option. Standard MOT Type 1 aggregate is even cheaper for sub-base work. For decorative use, pea gravel and standard slate chippings offer the best value per square metre.

Do I need a weed membrane under gravel or pebbles?

Always. A permeable geotextile weed membrane prevents weed growth, stops stone sinking into soil, and separates your decorative surface from the ground. Without one, weeds colonise any stone area within two seasons.

How deep should gravel be for a driveway?

For driveways, lay 50mm of decorative gravel over a compacted 150mm MOT Type 1 sub-base. For pebble driveways, go deeper — 75–100mm of stone. Always use solid edging to contain the material.

What are the best low-maintenance garden materials?

Gravel, slate chippings, and decorative pebbles over weed membrane are the ultimate low-maintenance ground cover. No mowing, no watering, minimal weeding. Add steel edging for clean lines and drought-tolerant plants for colour.
