20mm Limestone Chippings Bulk Bag

What Are 20mm Limestone Chippings? 

20mm limestone chippings are a versatile and hard-wearing decorative aggregate commonly used in landscaping, ground cover, and drainage applications. Sourced from natural limestone, these angular stones typically range in colour from light grey to off-white, providing a clean, contemporary look that complements both traditional and modern outdoor spaces.

Their 20mm size offers the ideal balance between visual appeal and practicality - small enough to compact well, yet large enough to allow excellent drainage. This makes them a popular choice for driveways, garden paths, borders, and even water feature surrounds.

Whether you're improving kerb appeal, suppressing weeds, or managing surface water, 20mm limestone chippings deliver reliable performance with minimal maintenance.

Applications

• Paving & Patio Edging: Provides a neat decorative border around paving slabs, helping improve drainage and suppress weed growth when installed over a membrane.
• Shed and Greenhouse Surrounds: Delivers a stable, free-draining surface around garden structures, reducing mud and protecting foundations from excess moisture.

Installation Tips

• Prepare the Area: Clear the site of weeds, roots, and debris. Lay a quality weed membrane to reduce regrowth and keep the chippings clean.
• Add a Sub-Base (If Required): For driveways or high-traffic areas, lay a sub-base of MOT Type 1 or crushed concrete for added strength and stability.
• Spread the Chippings: Evenly spread to an approximate depth of 40-50mm for paths or up to 75mm for driveways. Use a rake to level and compact lightly for best results.
• Edge the Area: Install edging to contain the chippings and prevent movement over time.

Maintenance Advice

• Rake Occasionally: Redistribute stones and remove debris to keep the surface fresh and even.
• Weed Control: Keep an eye out for weeds growing through and remove as needed.
• Top-Up Annually: Replenish any low areas or compacted patches to maintain full coverage and depth.
