{"product_id":"2-5-inch-base-course","title":"2 1\/2 Inch Base Course Gravel for Fill and Base Layers","description":"\u003cp\u003eAlso known as 2 1\/2 Inch Select Borrow or 2 1\/2 minus, this material runs from 2 1\/2 inch rock down to fines in a graded blend built to compact. The combination of mid-sized rock and fine material is what lets it lock together into a firm, load-bearing base, which makes it useful as both a fill and a structured base layer in spots where 6 Inch Minus runs too large to finish cleanly.\u003c\/p\u003e\n\u003cp\u003eIn practice it most often serves as a middle layer under house pads, driveways, and parking areas. It is commonly placed over a coarser lift such as 6 Inch Minus, then topped with a finer 1 1\/2 inch or 3\/4 inch course to reach final grade. Laid in lifts and compacted, the fines drive into the gaps between the rock and bind the layer so it holds its shape under load.\u003c\/p\u003e\n\u003cp\u003eThink of 2 1\/2 Inch Base Course as the step between rough fill and a finished base. It is too coarse to be a final wear surface on its own, but it builds depth and stability faster than the finer courses, so using it in the right layer saves both material and time. If you are unsure how deep to run it or what to cap it with, your contractor can size the layers to the job.\u003c\/p\u003e\n\u003ch2\u003eCommon uses:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCompacted base under pads, driveways, and parking\u003c\/li\u003e\n\u003cli\u003eMiddle layer over 6 inch minus\u003c\/li\u003e\n\u003cli\u003eStructured fill where a finer grade is needed\u003c\/li\u003e\n\u003cli\u003eBuilding depth before a finer top course\u003c\/li\u003e\n\u003cli\u003eLeveling areas that need a firm base\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eGood to know:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAlso called 2 1\/2 Select Borrow or 2 1\/2 minus\u003c\/li\u003e\n\u003cli\u003eGraded from 2 1\/2 inch rock down to fines\u003c\/li\u003e\n\u003cli\u003eCompacts into a firm, load-bearing layer\u003c\/li\u003e\n\u003cli\u003eBest capped with a finer course for the finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn stock now.
