Materials for Sandown Projects

Raising grade and building pads is where most Sandown jobs begin. You need fill that compacts and stays put under a slab, a shed, or a driveway that has settled. Here is what to order, sorted by the project in front of you.

For a driveway, lay crushed gravel first and compact it in lifts. Crusher run works when you want the surface to bind and tighten up. Top it with driveway gravel if you are refreshing an existing drive that has gone loose.

For a patio, bed the pavers on stone dust. It is the New England default under flatwork, and it screeds flat without fighting you.

For a drain, order drain rock and keep it washed and open. Pea stone handles walkways, play areas and shallow drainage, while 3/4 inch crushed stone covers drainage beds and construction entrances.

Building pads need bulk before anything pretty. Bring the grade up with crushed gravel, compact in shallow lifts, and let the material do the work under the slab.

Ground and Conditions in Sandown

Sandown sits in the Southern interior and Merrimack Valley ground zone. That means stony glacial till and ledge on the hills, with sand and gravel outwash in the valleys. Two sites a mile apart can drain completely differently.

Sandy outwash drains fast, so a base there stays firm. Dense till with a hardpan layer drains slowly, and water sits right where you wanted your sub-base. In mud season, thawed soil holds water above ground that is still frozen.

That is why base depth matters more than base price. On slow-draining till, dig deeper, use a coarse open stone like #4 crushed stone or #57 stone in the bottom, and compact every lift. Skip that and the pad pumps, cracks and settles.

Frost heaves show up in gravel drives as the ground thaws each spring. Frost depth runs about 4 feet in most towns, and the town building official sets footing depth. Base work runs from the end of mud season into late fall, because frozen ground stops compaction through the winter.

If your site touches a stream bank or a culvert outlet, rip rap armors the slope against spring runoff and heavy rain scour.

Delivery to Sandown and the Surrounding Area

Order online and choose your quantity by the ton, or by the yard if you are thinking in volume. Measure the area, set your depth, and let the site handle the conversion. If you are close, order a little heavy rather than a little light.

Bulk delivery drops the load where your machine can reach it, so tell us where the truck can get in and where you want the pile. A long drive, a tight gate or a soft shoulder all change how the drop works.

Sandown is in Rockingham County, and we deliver across the area, including Derry, Salem, Londonderry, Portsmouth and Hampton. Screened loam, garden soil, mason sand, washed sand and shredded mulch ride on the same order as your stone.

Questions from Sandown Contractors and Homeowners

What is the best base under pavers in Sandown?

Compacted crushed gravel is the base, then stone dust is the bedding layer the pavers sit on. On slow-draining till, dig deeper and use a coarse open stone at the bottom before you build up. Both layers need compaction in shallow lifts. Get the base right and the patio stays flat through freeze-thaw instead of rocking the following spring.

Do you supply contractors working in Sandown?

Yes. Contractors, builders and homeowners all order the same way, online by the ton, with delivery to the site. Place your order, set the quantity and the drop point, and we bring the load. If you are running base and fill across several jobs in Rockingham County, order each one as you need it.
