Materials for Hillsborough Projects

Most work in Hillsborough starts with fill and sub-base: raising grade, building a pad, or putting down a layer that will carry what goes on top. Crushed gravel is the standard New Hampshire base material, used under driveways, parking pads and shed bases.

Crusher Run is the same idea where you want a material that compacts and binds. It locks together under a plate or a roller and makes a firm pad for a garage, a shed or a drive.

Once the base is set, the surface and finish materials come in by project type.

For a driveway, top a compacted base with Driveway Gravel. For a patio, set the pavers on Stone Dust over a crushed base, with Washed Sand for leveling under a slab. For a drain, run #57 Stone or Drain Rock in the trench and outlet, and use RipRap where water leaves a pipe and hits bare ground.

Pea Stone covers walkways and play areas, and River Rock or Large River Rock handles decorative beds and dry creek beds. New Hampshire landscapers call topsoil loam, and screened loam is what goes down before seed. Garden Soil is blended for raised beds and planting areas.

Ground and Conditions in Hillsborough

Start with the soil, because it decides how much base you need. Sandy valley outwash drains fast and will swallow a thin layer of crushed gravel. Dense till with a hardpan layer drains slowly, so water sits on top of the base and works it loose.

In mud season, thawed soil holds water above ground that is still frozen. That is the worst time to build a pad. Compact a base on ground that is still frozen and it will move when the thaw comes.

Winters here bring repeated freeze-thaw and frost heaves in gravel drives and roads each spring. Frost depth runs about 4 feet in most towns, and the town building official sets footing depth. That is why an under-built base fails: the material is too thin for the ground under it.

River and stream banks also scour after heavy rain and snowmelt, as in the May 2006 flood that set record flows on several rivers in this part of the state. RipRap on a bank or a culvert outlet holds that ground. Base, driveway and paver work runs from the end of mud season into late fall, and frozen ground stops compaction through the winter.

Questions from Hillsborough Buyers

What is the best base under pavers in Hillsborough?

Compacted crushed gravel is the base, then a thin bedding layer of Stone Dust. Crushed gravel gives you a firm, draining layer that will not pump when the ground is wet. Stone Dust screeds flat and locks the pavers in place. Build the base thick enough for the ground under it, because the base carries the load, not the bedding.
