This mix includes everything from fines (dust) up to 2\" stone, allowing it to lock together tightly while also providing the strength needed for deeper construction layers.\u003c\/p\u003e\n\u003cp\u003eIn Southwestern Ontario, a proper sub-base matters. Heavy clay soils and freeze-thaw cycles can cause shifting and heaving, especially when a driveway or patio base is built too thin. A thicker layer of 0–2\" helps spread loads, stabilize soft subgrade, and reduce movement that can lead to rutting, cracking, or settling.\u003c\/p\u003e\n\u003ch2\u003eBest Use Cases\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNew driveway construction:\u003c\/strong\u003e Often used as the bottom 6–12 inches of a full driveway build before adding a smoother top layer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeep fill and grade building:\u003c\/strong\u003e Cost-effective for filling deeper excavations, raising low areas, and building up rough grade.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoft ground stabilization:\u003c\/strong\u003e Helps bridge wet or spongy subgrade better than smaller stones, making it useful where clay holds moisture.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoad base and heavy-use areas:\u003c\/strong\u003e Suitable for base layers under areas that see heavier loads or frequent traffic.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eInstallation Note\u003c\/h2\u003e\n\u003cp\u003eBecause of the larger stone size, 0–2\" does not finish smooth and is designed to be buried.

Installing in lifts and compacting thoroughly will improve long-term performance.\u003c\/p\u003e","brand":"Phatty's Landscape Supply","offers":[{"title":"Default Title","offer_id":48366413086963,"sku":null,"price":176.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0799\/6856\/7539\/files\/36095C3C-55DF-4E6A-BF31-6DEA8415C324.jpg?v=1777042390","url":"https:\/\/phattys.ca\/products\/limestone-0-2-granular-b","provider":"Phatty's Landscape Supply","version":"1.0","type":"link"}
