Bulk Aggregates for Drainage in Lempster, NH

Wondering what to order for a wet yard or a soggy drive? New Hampshire Rock Supply handles gravel and aggregate delivery in Lempster, NH, and for most drainage jobs the answer starts with washed stone. Lempster sits on stony glacial till and ledge, so water sheds off the hills fast and then sits in low spots that hold silt and clay.

Order crushed gravel by the ton for the base and washed stone for the water. Tell us what the water is doing and we will point you at the right size.

Materials for Lempster Projects

Drainage work here means moving water away from a foundation, a drive, or a low corner of the yard. Washed stone is the backbone of that work because the fines are rinsed out, so voids stay open and water keeps moving instead of silting the bed shut.

The list below runs coarsest to finest, with what each size is good for.

For a downspout run or a drywell, line the trench with drain rock and keep the fabric wrapped so silt cannot fill the voids. Where a culvert dumps onto a bank, rip rap locks the soil down before the next spring snowmelt cuts it away.

Drive and pad work is different. Crushed gravel is the standard New Hampshire base material for driveways, parking pads and shed bases, and crusher run binds and compacts where you want a tighter surface. Top both with 3/4 inch crushed stone if you want the surface to shed water instead of holding it.

Finishing materials follow the same logic. Stone dust beds pavers and flagstone. Pea stone, which most New Hampshire yards call Natural Pea Gravel, suits walkways, play areas and light drainage. Screened loam covers the lawn and bed prep, and shredded mulch holds moisture in the beds through summer.

Ground and Conditions in Lempster

Timing decides more of this work than material choice does. Base, driveway and paver work runs from the end of mud season into late fall. Frozen ground stops compaction through the winter, so a load spread on a frozen subgrade will not lock up.

That matters on both sides of town. Silty and clayey valley soils and dense hillside till drain slowly and stay soft through mud season, while sandy terraces and outwash drain quickly. Dig a drainage trench in the wrong week and you are backfilling mud.

Frost heaves in gravel drives and hill-town roads show up every spring. Winters here bring repeated freeze-thaw, and frost depth runs about four feet in most towns. Your town building official sets footing depth, so confirm it before you pour.

Plan the base depth around that cycle and around what the ground does in spring. A thicker compacted base of crushed gravel or crusher run takes more material now and saves a rebuild later. On the wetter lots, put the drainage layer in before the base goes down.

Delivery to Lempster and the Surrounding Area

Order online and we deliver bulk material to Lempster and the rest of Sullivan County, including Claremont, Newport, Charlestown, Grantham and Sunapee.

Quantity is usually figured by the ton for stone and gravel, and by the yard for sand, loam and mulch. Enter your length, width and depth in the calculator to convert it, or use your own numbers if you have them.

Lead time depends on the material and the week, and mud season is the busiest stretch of the year. Place the order with a little room before your crew is on site. Trucks need a clear, firm approach so the load can be tailgated where you want it, not dropped at the road.
