{"product_id":"drainage-gravel","title":"Drainage Gravel | 20mm Free-Draining Stone for Drainage \u0026 Paths","description":"\u003cp\u003eDrainage Gravel is a practical 20mm stone for improving drainage in landscaping and building projects. It gives a stable, permeable layer that lets water through instead of pooling — ideal around drainage runs, behind retaining walls, under paths and driveways, and around the base of garden buildings. Its natural browns, greys and buffs also make it a tidy, budget-friendly top-dressing.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size: 1rem;\"\u003eProduct Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStone:\u003c\/strong\u003e Natural gravel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Brown, grey and buff\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade:\u003c\/strong\u003e Approx 20mm down\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBest for:\u003c\/strong\u003e Drainage runs, driveways, paths and around garden buildings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack sizes:\u003c\/strong\u003e Jumbo bulk bag (approx 1,000kg), standard bulk bag (approx 750kg), midi bulk bag (approx 500kg), or 25kg handy bags in packs of 10, 20 or 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoverage:\u003c\/strong\u003e Approx 10–12m² per tonne at 50mm (2in) depth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNatural stone:\u003c\/strong\u003e Shades vary between batches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupplier:\u003c\/strong\u003e Dandy's Topsoil \u0026amp; Landscape Supplies\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2 style=\"font-size: 1rem;\"\u003eAlso in the Landscaping Range\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/soakaway-gravel-stone-60-140mm-jumbo-bag\"\u003eSoakaway Stone\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/welsh-brown-gravel\"\u003eWelsh Brown Gravel\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sand-and-gravel-mix-ballast\"\u003eSand \u0026amp; Gravel Ballast\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eBrowse more in our \u003ca href=\"\/collections\/building-drainage-aggregates\"\u003eBuilding \u0026amp; Drainage Aggregates\u003c\/a\u003e range, or explore the full \u003ca href=\"\/collections\/landscaping\"\u003eLandscaping\u003c\/a\u003e collection at Oak \u0026amp; Outdoor.\u003c\/p\u003e","brand":"Dandy's Topsoil \u0026 Landscape Supplies","offers":[{"title":"Jumbo Bulk Bag approx 1000kg ⭐️ BEST BUY!","offer_id":55243633197383,"sku":"DDGJBB","price":142.0,"currency_code":"GBP","in_stock":true},{"title":"Standard Bulk Bag approx 750kg","offer_id":55243633230151,"sku":"DDGSBB","price":129.0,"currency_code":"GBP","in_stock":true},{"title":"Midi Bulk Bag approx 500kg","offer_id":55243633262919,"sku":"DDGHBB","price":115.0,"currency_code":"GBP","in_stock":true},{"title":"40 x 25kg Handy Bags","offer_id":55243633295687,"sku":"DDG4025","price":259.15,"currency_code":"GBP","in_stock":true},{"title":"20 x 25kg Handy Bags","offer_id":55243633328455,"sku":"DDG2025","price":171.75,"currency_code":"GBP","in_stock":true},{"title":"10 x 25kg Handy Bags","offer_id":55243633361223,"sku":"DDG1025","price":128.05,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0979\/2418\/6439\/files\/WELSHBROWN20MM.jpg?v=1790946280","url":"https:\/\/oakandoutdoor.co.uk\/products\/drainage-gravel","provider":"Oak \u0026 Outdoor","version":"1.0","type":"link"}
