Heavy clay soil, low-lying areas, and the spring melt from our heavy snowpack all create drainage challenges that standing water, soggy lawns, and wet basements. 40mm drain rock is the material that solves those problems properly. The large angular stones create maximum void space between rocks, letting water move freely and fast without clogging or compacting over time.\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\u003eFrench drains and weeping tile systems\u003c\/strong\u003e — the primary use.

Spring melt, heavy rain, and overland flow from neighbouring properties can saturate yards quickly — leading to pooling, foundation seepage, and damaged landscaping.
