Gravel Guides for the Weeks the Ground Is Dry Enough
Base work here waits on the weather more than on the calendar, and the planning is best done while the clay is still too wet to touch. These guides cover the decisions worth settling in that gap, so the order is ready when the ground firms up.
Why a Piedmont drive ruts when the same build holds elsewhere
Clay softens under load and pumps fines up into the stone above it, which is why a layer that holds on firmer ground gives way here after a long wet spell. The base-depth guide covers shaping the subgrade, working in lifts, and what the finished compacted thickness actually means once the roller has been over it.
Crush and run or #57 stone for the drive I already have?
One binds and one drains, and the answer turns on a single question: is the layer underneath being rebuilt, or is the surface only being topped up? The comparison guide sets Crush and Run against #57 Stone on compaction, drainage and how each behaves once a car has been turning on it for a season.
How much ABC stone does the pad need, and at what depth?
The ABC guide takes the tonnage question directly: measuring, converting cubic yards to tons, and typical depths for drives, patios and parking pads. Pair it with the material calculators to get from a measured area to an order quantity, or go straight to ABC Stone if the depth is already settled.
For anything not covered here, the catalogue lists the size and grading of every material, and the common questions page answers the ones that come up between measuring and ordering.
Common questions
Which guide should I read first for a new gravel drive?
The base-depth guide, since the subgrade and the compacted thickness decide whether the drive holds. The tonnage question is easier to answer once the depth is settled.
Do these guides apply on the Coastal Plain as well?
The base-depth guide is written around Piedmont clay. On sandy ground the drainage problem largely disappears, but the binding still has to come from the fines in the stone, so the material choice holds even where the depth logic changes.
Is there a guide that gives a quantity for my own drive?
The guides explain the method and typical depths; the calculators do the arithmetic for your measurements and return cubic yards, tons and cubic feet.
