Yorklyn sits in New Castle County on ground that is often shallow to rock, so what goes under a patio matters as much as what sits on top of it.

Ground and Conditions in Yorklyn

Across the Piedmont and the Fall Line, loamy soil sits over deeply weathered saprolite and hard crystalline rock. On the ridges the rock comes close to the surface, and on the slopes above the stream valleys the soil turns stony.

A thin base shows its weakness fast on that ground. Water moves through the shallow soil, finds the rock, and works along the contact until the bedding shifts and the surface above it moves.

Sloping ground sheds water quickly, so runoff concentrates in the stream valleys and cuts into slopes where cover is thin. That is the case for a drainage layer under the flatwork, not just a compacted one.

Base, driveway and paver work runs most of the year here. Frozen ground in January and February is the main stop, and spring rain the main delay.

This is the coldest ground in Delaware, and repeated winter freeze and thaw lifts gravel drives and paver joints. New Castle County sets a frost depth of 32 inches, the deepest figure in the state, and that number belongs to the county rather than to Yorklyn.

Materials for Yorklyn Projects

Bedding is where a patio or walkway is won or lost. The layer under the pavers has to hold a level plane and pass water, and the right choice depends on what sits below it.

Stone Dust is the bedding material for pavers, flagstone and brick.

10 stone, and it also fills the voids in a compacted base.

Concrete Sand is washed sand used for bedding under pavers and slabs, for leveling, and in concrete mixes.

Mason Sand is a finer sand for brick and block work, paver joints and play boxes.

Below the bedding, GABC is the Delaware base material. It is graded aggregate base course, also written GABC Type B, and it is what you order for driveways, parking pads, shed bases and any layer that has to compact and hold.

Crusher Run is the everyday trade name for the same work, and it is also called dense graded. Use it on lanes, drives and base layers that need a binding, compacting stone.

For drainage and concrete work, #57 Stone is clean stone for drainage beds, underdrains, drive surfacing and concrete.

57 stone.
