The surface is the single biggest swing in an industrial outdoor storage budget — and the decision that most affects rents, maintenance, and how the yard holds up. Here's how to choose.
There's no universally "right" surface for an IOS yard. The best choice depends on what you'll store, how heavy and frequent the traffic is, your drainage requirements, and how long you plan to hold the asset. The three common options are stabilized aggregate, asphalt, and concrete.
Stabilized aggregate (millings / crushed base)
A compacted, stabilized aggregate surface — often using recycled asphalt millings or crushed base over a prepared subgrade.
- Pros: lowest upfront cost, fast to install, easy to expand or repair, good drainage when built right.
- Best for: trailer and container storage, lower-frequency traffic, owners optimizing initial cost or testing a market.
- Trade-offs: needs periodic regrading and replenishment; can rut under concentrated heavy loads or constant turning.
Asphalt
A flexible paved surface over a compacted base — the middle ground between stabilized and concrete.
- Pros: smoother, more durable than stabilized, supports heavier and more frequent traffic, cleaner appearance, often stronger rents.
- Best for: active truck terminals, fleet yards, and yards marketed to credit tenants.
- Trade-offs: higher upfront cost; periodic seal-coating and crack maintenance; can soften under extreme point loads.
Concrete
The most durable — and most expensive — option, used where loads are heaviest or most concentrated.
- Pros: longest life, lowest maintenance, handles the heaviest point loads (container stacking, jacks, landing gear).
- Best for: container depots, heavy equipment yards, and high-turn areas like entrances and drive lanes.
- Trade-offs: highest upfront cost and longer cure time.
What actually drives the decision
- Tenant & load type: stacked containers and constant turning push you toward paved/concrete.
- Hold period: long holds favor paving (lower lifetime maintenance); short holds favor stabilized.
- Drainage & permitting: impervious paving changes stormwater calculations and may enlarge the required retention.
- Rent premium: a paved yard can command higher rents — run the math against the added cost.
Because we self-perform site work and surfacing, we can model these options against your pro forma and build the right combination — instead of defaulting to one surface for the whole yard.
FAQ
Is stabilized aggregate "good enough" for an IOS yard?
Often yes — for trailer and container storage with moderate traffic, a properly built stabilized yard performs well at a fraction of paving cost.
Does paving increase my stormwater cost?
It can. More impervious surface usually means more required retention/detention — factor it into both budget and usable acreage.
Can I phase the surfacing?
Yes. Many owners stabilize first to reach lease-up, then pave high-traffic zones as the yard matures.
