Large River Rock and Bulk Aggregates for Kensington, MD

Maryland Rock Supply delivers gravel and aggregate delivery in Kensington, MD for driveways, drainage and planting work. CR-6 is the base material most crews here ask for, a compacting blend of crushed stone down to dust. Kensington sits on rolling Piedmont ground, where silty soil turns soft when it stays wet.

Coarse stone holds slopes, swales and stream banks in place around Kensington, and finer materials take over on paths and beds.

Storm runoff moves fast here. It scours bare banks, cuts under drive edges and leaves ruts where water sits. Coarse, open-graded stone is the fix, and the size you pick depends on how much water and energy the spot has to handle.

Start with rip rap where a slope drops toward a stream valley or a swale carries runoff off the lot. Large river rock works the same job in dry creek beds, and it reads better than plain rip rap in a planted yard.

Below that, #4 crushed stone or #57 Stone handles heavy drainage, French drains and driveway topping, and #57 stone is also the usual concrete aggregate. For finer work, #8 crushed stone sets paver joints and small-chip surfacing.

Base layers come next. CR-6 is the standard compacting base for a Kensington drive, and crusher run is a separate product where you want a binding blend. Stone dust, listed here as screenings, beds pavers and flagstone. On top, Natural Pea Gravel suits walkways and play areas, and Top Soil rebuilds grade after grading before seed or sod goes down.

Ground and Conditions in Kensington

Base, driveway and paver work runs spring through late fall. Mid-winter freezes and wet spells stop compaction, but for shorter stretches than crews see farther west in the mountains.

Winter still brings regular freeze-thaw cycles, with a frost depth of 30 inches in most county codes across this zone. A drive built on a thin base or on wet, silty soil heaves and ruts when that cycle repeats.

So the base depth and the drainage layer matter more here than the top dressing does. Give the drive a crown, plus a ditch or drain where water collects, and compact CR-6 in lifts rather than one deep pass. If grading leaves bare, sloping ground, arm it with rip rap or river rock before the next storm season.

Order online and choose your quantity by the ton or by the cubic yard. Bulk delivery to a Kensington site means a truck placing material where the driver can reach it, so mark the drop spot and clear the approach before the truck arrives.

Coverage reaches the rest of Montgomery County, including Germantown, Silver Spring, Gaithersburg, Rockville and Bethesda. Lead time depends on material and on the route, so plan a delivery around your grading and compaction schedule rather than after it.
