Large River Rock and Bulk Aggregates for Lexington, MA

For gravel and aggregate delivery in Lexington, MA, start with processed gravel. It is the standard Massachusetts base material, specified as M1.03.1 processed gravel for subbase and used under driveways, parking pads, walks and shed bases. Massachusetts Rock Supply delivers it by the ton, along with the coarse stone this town needs for slope, swale and bank work. Lexington sits on stony glacial till, so drainage and grade control matter here.

Materials for Lexington Projects

Erosion control drives most of the stone orders we see in Lexington. Coarse, angular rock interlock and hold a slope, while rounded stone moves and slides. Here is the range by size, coarsest to finest, with what each one does on a Lexington site.

• RipRap: stream bank, culvert outlet and slope stabilization, and armoring banks against storm waves.
• Railroad Ballast: heavy coarse stone for hard standing, track beds and severe drainage.
• #4 Crushed Stone: heavy drainage, construction entrances and trench bottoms. The 1 1/2 inch stone size many suppliers list falls on this same page.
• #57 Stone: drainage, French drains and concrete aggregate. The workhorse size for a swale or a drain field.
• Large River Rock: dry creek beds and heavier decorative and erosion work, where you want the water to read as a feature instead of a scar.

Below that size, Drain Rock handles French drains, drywells, foundation drains and downspout runs. Processed Gravel is the compacting base under a drive or paver area, and Stone Dust is the New England default bedding under flagstone and pavers.

Ground and Conditions in Lexington

Lexington sits on stony glacial till and drumlin hills, much of it over dense, slowly draining lower till. That lower till holds snowmelt and heavy rain near the surface instead of letting it soak away. Plan for a drainage layer, not just a base.

Frost is the other factor. State code puts frost depth at 48 inches. Repeated freeze-thaw in late winter and early spring heaves and breaks up gravel drives and pavement, and late-winter thaws bring the worst soft-ground and pothole conditions. Build the base deep enough to ride through that cycle.

Base, driveway and paver work runs spring through late fall. Frozen ground stops compaction in winter, so time a delivery for workable ground.

Delivery to Lexington and the Surrounding Area

Massachusetts Rock Supply covers Lexington and the rest of Middlesex County, including Cambridge, Lowell, Newton, Somerville and Framingham. Order online and pick your material and quantity. Deliveries are scheduled around your project, so expect a typical lead time rather than same-day turnaround.

Order by the ton or the yard. For a driveway base, measure length and width, decide your compacted depth, then convert to tons. If you are unsure, the calculator will turn those measurements into a load size. A bulk truck needs clear access and a firm spot to set up.
