Mason Sand for Patios in Silver Spring, MD

Maryland Rock Supply stocks gravel and aggregate delivery in Silver Spring, MD, and the patio work around here starts with what goes under the pavers. CR-6, crusher run, stone dust, mason sand and washed sand all leave the yard sized for the job. The ground in this part of Montgomery County is often flaky with mica, so bedding and base both matter.

Materials for Silver Spring Projects

A patio or walkway stays flat only as long as its bedding layer holds. Stone dust, which many yards call screenings, packs tight under pavers and flagstone and holds a flat surface without shifting. Order Screenings for the bedding course, then finish the joints with a finer washed stone.

Below the bedding you still need a compacting base. CR-6 is the standard Maryland base material, a blend of crushed stone down to dust that locks together under a plate compactor. It goes under patios, driveways, parking pads and shed bases. Order CR-6 for the base course and keep it at the depth your plan calls for.

Some crews prefer crusher run for the same job. It is a separate product from CR-6, and it also binds and compacts well. Order Crusher Run if that is what your spec names.

For the joints and the fine finish, #8 stone and #89 stone both work. #8 stone is a small washed chip used in paver joints, small-chip surfacing and concrete aggregate. #89 crushed stone is smaller still, sized for tight bedding and narrow joints. Order #8 Crushed Stone or #89 Crushed Stone to lock the surface in.

Where a patio meets a downspout or a low corner, drainage has to move water away. #57 stone is the washed stone most crews reach for, and it also tops drives and mixes into concrete. Order #57 Stone for a drainage layer or a French drain run.

Ground and Conditions in Silver Spring

A thin base shows itself fast here. The soil across the Central Maryland Piedmont is loam, silt loam and clay loam weathered from schist and gneiss, often carrying mica and rock fragments. When it saturates, it turns soft and will not compact.

That is why a patio dug on a thin base ruts and rocks within a season. Doing it right means excavating far enough down, compacting the subgrade, then building the base in lifts. Rolling slopes shed storm runoff toward the stream valleys quickly, so plan a crown, a ditch or a drain where water collects.

Winter matters too. Regular freeze-thaw cycles heave and rut drives built on a thin base or on wet, silty soil, and frost depth runs about 30 inches in most county codes across this zone. Base, driveway and paver work runs spring through late fall, with mid-winter freezes and wet spells stopping compaction for shorter stretches than in Western Maryland.

Erosion is the other local driver. Summer thunderstorms and tropical storm rain scour stream banks, and bare sloping ground washes during grading. Rip rap armors banks and culvert outlets, and a silt fence or straw mat protects an open slope until grass takes.

Delivery to Silver Spring and the Surrounding Area

Order online and choose your quantity by the ton or by the cubic yard. Bulk material is sold by weight, but most homeowners think in volume, so decide which measure your plan uses before you order. A quick way to estimate is length times width times depth in feet, then divide by 27 for cubic yards.

Delivery covers Silver Spring and the rest of Montgomery County, including Germantown, Gaithersburg, Rockville, Bethesda and Potomac. Tell us where the truck can set down and how far the pile needs to be from the work. A patio bedding order usually lands close to the excavation so you are not wheeling sand across the yard.
