{"product_id":"40mm-wash-rock-calgary","title":"40mm Wash Rock — Bulk Delivery Calgary","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e40mm washed rock is clean, consistent, and built for Calgary's toughest drainage and landscaping applications. The washing process removes clay, dust, and fine debris — leaving a rock that drains freely, looks clean in a yard, and performs reliably in both structural and decorative applications. The 40mm sizing creates generous void space between rocks for fast water movement, making it one of the most effective drainage materials we carry.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat it's used for\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eDrainage systems and French drains\u003c\/strong\u003e — the clean, washed surface prevents fine particles from clogging the void space between rocks, keeping drainage systems flowing freely for years\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eFoundation and footing drainage\u003c\/strong\u003e — placed around foundations to move water away from the structure quickly and prevent hydrostatic pressure\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eRetaining wall backfill\u003c\/strong\u003e — the large void space allows water to drain freely behind walls without building up pressure\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eConcrete and asphalt base\u003c\/strong\u003e — used as aggregate in concrete mixes and as a stable sub-base layer for roads and paved surfaces\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eDecorative garden beds and ground cover\u003c\/strong\u003e — the washed surface gives a cleaner, brighter appearance than unwashed rock, making it a popular decorative choice for open beds and borders\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePathways and driveways\u003c\/strong\u003e — large enough to stay in place under foot and vehicle traffic, with a cleaner look than standard crush\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eDry creek beds and water features\u003c\/strong\u003e — the washed finish looks natural and holds up well around water\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWashed rock vs drain rock — what's the difference?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eBoth are 40mm angular rocks used for drainage, but washed rock has been cleaned of fines and clay particles.
