Bulk Aggregates for Drainage in Berlin, NH
How do you keep water moving away from a foundation in the North Country? For gravel and aggregate delivery in Berlin, NH, New Hampshire Rock Supply starts with washed stone. That means crushed gravel for driveways and pads, and clean stone for drains that have to stay open under snowmelt and a long mud season.
Drainage stone comes in several sizes, and the right one for a French drain, drywell or downspout run depends on how water moves through Berlin's stony glacial till and ledge.
Materials for Berlin Projects
Drainage drives most jobs here. A French drain, a drywell, a foundation drain or a downspout run all need washed stone with the fines washed out, so water moves through the voids instead of sitting in the pipe. Order the size by the pipe and the trench, not by what is on the pile.
Drain stone, coarsest to finest
- #4 Crushed Stone: heavy drainage, trench bottoms and construction entrances. The open, coarse choice for a deep run.
- Railroad Ballast: hard standing and severe drainage on soft or saturated ground, including track beds.
- #57 Stone: the standard backfill around perforated pipe in French drains and drywells.
- #67 Stone: the same job at a slightly smaller size, easier to work into tight trenches.
- Drain Rock: sized for French drains, drywells, foundation drains and downspout runs.
- #8 Crushed Stone and #89 Crushed Stone: small washed stone for pipe bedding and paver joints.
For driveways, crushed gravel is the base most Berlin buyers ask for, and it compacts into a firm surface. Use Crusher Run where you want the stone to bind, and Driveway Gravel to top an existing drive. Pea stone handles walkways and play areas, stone dust beds pavers, and screened loam or garden soil finishes the yard.
Ground and Conditions in Berlin
Plan the work around the season, not the calendar. The colder climate leaves a shorter working season than in the south, so base, driveway and paver work fits between a late mud season and the fall freeze. Book the delivery close to the dig, because a pile left through a wet spring slumps.
Winters here are much colder than southern New Hampshire. The long frozen season brings frost heaves in gravel drives each spring, so base depth matters. Frost depth is set by the town building official, and it can be deeper than the 4 feet common in southern towns, so confirm the local figure before you build.
Mud season is the other driver. Thawed soil holds water above ground that is still frozen, and river ice jams add to spring flooding on low ground. A drainage layer under a slab or drive is what protects it. Spring runoff and ice jams also scour river banks, which is where RipRap pays for itself.
