Materials delivered in Kent County

Processed gravel is the base material most Rhode Island work is specified around. It is aggregate crushed or screened from natural boulder, cobble and gravel.

Section 301 covers aggregate and gravel base courses, Section 302 gravel borrow subbase courses.

Town road standards in Rhode Island stack bank run gravel borrow below and processed gravel above. Order processed gravel for driveways, parking pads, walks and shed bases.

Yards here sell it as 3/4 processed for residential drives and patio bases, and 1 1/2 inch processed where a deeper base has to carry heavy equipment.

Bank run gravel is unprocessed pit sand and gravel, dug and screened rather than crushed. Use it for bulk fill, raising grade, and the first compacted lift under a processed base.

Fill dirt fills low spots and backfills foundations where nothing finished goes on top. Stone dust beds pavers, bluestone and flagstone and packs garden paths.

Washed stone handles water. 3/4 inch crushed stone, sold locally as blue stone, suits drainage beds, trench backfill and construction entrances.

3/8 inch crushed stone covers fine drainage and pipe bedding. 1 1/2 inch crushed stone takes heavy drainage and trench bottoms.

#57 stone and #67 stone are specification sizes for French drains, drywells and concrete aggregate. Drain rock comes as clean or washed stone in an inch size.

Riprap armors shoreline banks, culvert outlets and stream banks, sold in the 4 to 10 inch range. Pea stone covers walkways, play areas and drip edges.

River rock and large river rock finish decorative beds and dry creek beds. Mason sand mixes mortar and beds pool bases.

Concrete sand mixes concrete and beds pipe. Screened loam builds lawns over stony till, and garden soil fills raised beds.

Shredded mulch holds moisture in beds and tree rings through summer.

Ground conditions across Kent County

Kent County spans two ground regions. Around Warwick, West Warwick and East Greenwich the lowland sits on glacial till with pockets of valley sand and gravel over Narragansett Basin sandstone, shale and conglomerate.

Made ground is common there, from filled cove and wharf land to a century of re-graded house lots. Dig depth is unpredictable lot to lot, because old fill, buried slab and ledge turn up in the same neighbourhood.

Water sheds fast off tight lots with a high paved fraction, and made ground settles unevenly and holds it. That is why a compacted processed gravel base matters more than the surface stone on a drive there.

In Coventry, West Greenwich and Greene the uplands are granite and gneiss under stony glacial till, with ledge and boulders close to the surface. Excavation depth and fill volume are harder to guess here than anywhere else in Rhode Island.

Dense till with a hardpan layer sheds water rather than taking it, so snowmelt and thaw sit on the surface and run down slope across drives. Plan a drainage layer with clean stone and expect more fill than the lot suggests.

Runoff cuts down slope on unpaved drives and town roads, and culverts wash out after heavy rain and thaw. Riprap and coarse stone protect those outlets and banks.

Base, drive and paver work waits for the frost to come out and the till to drain in spring, and finishes earlier in the fall than on the coast. Frozen ground stops compaction in midwinter.

Frost depth is 40 inches by state code, and the town building official sets footing depth.

Choosing the right material

Providence County shares both of Kent County's ground regions, the Narragansett Bay lowland and metropolitan Providence and the Western uplands. Its ground also takes in Blackstone Valley and the northern mill towns.

Where the ground is the same, the base and drainage choice is the same, so the material reasoning carries over.

That extra valley ground is the difference worth knowing. Where a lowland lot in Kent County sits on made ground, a valley lot can sit on its own mix of river deposits.

Either way, the answer starts with what the ground does with water and ends with a compacted processed gravel base.
