Bulk Material Delivery in Londonderry, NH

What do you order when a slope, swale, or stream bank keeps washing out? You order coarse stone, sized for the water you are actually fighting. New Hampshire Rock Supply handles gravel and aggregate delivery in Londonderry, NH, from crushed gravel for drives to rip rap for bank armoring. Londonderry sits on stony glacial till and ledge, so the ground drains fast on the hills and stalls on the flats.

Materials for Londonderry Projects

Erosion work is where most Londonderry orders start. Spring runoff and heavy rain scour river and stream banks across the southern interior, so the right size of stone matters more than the volume you buy. Work from the coarsest stone down to the fines.

• RipRap is the heavy option for stream banks, culvert outlets, and slope armoring where fast water pulls soil away.
• Drain Rock handles French drains, drywells, foundation drains, and downspout runs that need water to move underground.
• 3/4" Crushed Stone works for drainage beds, drive surfacing, and construction entrances that see constant traffic.
• Crushed Gravel is the standard New Hampshire base for driveways, parking pads, and shed bases.
• Stone Dust beds pavers, flagstone, and patios, the default under flatwork in New England.

Swales and ditch lines usually want a clean, open-graded stone that lets water drop through instead of running along the surface. Rip rap on the banks and drain rock in the trench solve two different problems, so plan them as separate orders. On flatter ground, crushed gravel and stone dust carry the load once the drainage is right.

Ground and Conditions in Londonderry

Timing drives everything here. Base, driveway, and paver work runs from the end of mud season into late fall, and frozen ground stops compaction through the winter. In mud season, thawed soil holds water above ground that is still frozen below, so a trench that looks fine can fill overnight.

Frost heaves in gravel drives and roads show up each spring as the ground thaws. Frost depth runs about 4 feet in most towns, and the town building official sets footing depth, so plan your base depth around that number rather than guessing.

Drainage follows the ground you build on. Sandy valley outwash drains fast, while dense till with a hardpan layer drains slowly and needs a real drainage layer, not just a thicker base. On the hills, ledge and stony till mean you excavate less than you expect and order less fill than you planned. Get your drainage stone in before the fall window closes, and the whole job compacts better.
