How deep can you excavate without shoring in Central Ohio?
In Central Ohio, you can excavate up to 5 feet deep without shoring if the trench is in stable soil and workers are not present in the trench. However, Brookston-Crosby clay soils are often unstable and waterlogged, so shoring or sloping may be needed at shallower depths for safety and compliance.
The Quick Answer
- You can usually excavate up to 5 feet deep without shoring in Central Ohio if soil is stable and no workers enter the trench.
- Brookston-Crosby clay soils in the region are poorly drained and may require shoring at shallower depths.
- Ohio law requires an Ohio 811 utility locate at least 48 hours before any excavation.
- Excavation includes footers, foundations, ponds, trenching, and site grading.
- Owner Lee Carson, U.S. Army Ranger (Ret.), has operated Fortress Level Construction since 2009.
- Flat-rate, owner-walked quotes are provided, with responses in 2-3 business hours.

Brookston-Crosby clay soils are common in Central Ohio and tend to be poorly drained, which can make them less stable and more prone to collapse. Wet or saturated clay increases the risk, so even shallow excavations may require shoring or sloping for safety. Soil moisture and structure are key considerations.
Shoring or protective systems are legally required when trenches are deeper than 5 feet or if the soil is unstable, regardless of depth. OSHA and Ohio regulations prioritize worker safety, so even shallow trenches may need shoring if there is any risk of collapse or the soil is not considered stable.
You must contact Ohio 811 at least 48 hours before any excavation. Utility companies will mark underground lines to prevent accidental strikes. This is required by Ohio Revised Code 3781.28 and applies to all excavation projects, including residential and commercial sites. Failing to do so can lead to fines and safety hazards.
Fortress Level Construction follows all state and federal safety laws, including utility locates and soil assessment. Owner Lee Carson personally walks each site, evaluates soil conditions, and ensures proper shoring or sloping is used when required to protect workers and property. Safety is always a top priority on every project.
What are the excavation depth rules without shoring in Ohio?
Ohio regulations allow excavation up to 5 feet deep without shoring in stable soils if no workers are in the trench. However, local soil conditions, like the Brookston-Crosby clay in Central Ohio, can require shoring at shallower depths. Always assess soil stability and moisture before digging to ensure compliance and safety.
State and federal regulations set 5 feet as the maximum depth for unshored trenches in stable soil, provided no workers enter the trench. If the trench is deeper or the soil is unstable, shoring or sloping is required.
Brookston-Crosby clay soils in Central Ohio often hold water and may not be stable, so safety measures like shoring may be needed even at shallower depths.

Why does Brookston-Crosby clay affect excavation safety?
Brookston-Crosby clay is poorly drained and becomes unstable when wet, increasing the risk of trench collapse. This makes excavation riskier, especially in spring when water retention is highest. Proper soil assessment and protective measures are essential for safe excavation in these conditions, regardless of trench depth.
Brookston-Crosby clay soils are common in Central Ohio and are known for holding water, especially during wet seasons. This can cause soil walls to weaken and collapse unexpectedly.
Because of this, excavation projects in these soils often require shoring or sloping, even if the trench is less than 5 feet deep, to ensure worker safety.

How does excavation depth without shoring compare in different soils?
Excavation depth limits without shoring depend on soil stability. Brookston-Crosby clay in Central Ohio often requires shoring at shallower depths than more stable soils. Always assess soil type and moisture before determining if shoring or sloping is needed for a safe excavation project.
| Soil Type | Max Depth w/o Shoring | Water Drainage | Collapse Risk |
|---|---|---|---|
| Stable Sand/Gravel | 5 ft | Good | Low |
| Brookston-Crosby Clay (dry) | Up to 5 ft | Poor | Moderate |
| Brookston-Crosby Clay (wet) | Less than 5 ft | Very Poor | High |
| Silty Soil | Up to 5 ft | Moderate | Moderate |
| Rock | More than 5 ft | Excellent | Very Low |

Frequently asked questions
Yes, OSHA and Ohio regulations require shoring, sloping, or another protective system for trenches over 5 feet deep, regardless of soil type, unless the excavation is made entirely in stable rock. This is to protect workers from trench collapse, especially in unstable or waterlogged soils like Brookston-Crosby clay.
Yes, Ohio law requires you to contact Ohio 811 at least 48 hours before any excavation, regardless of project size, to prevent utility strikes and ensure safety. This applies to all excavation work, including residential and commercial sites, and is enforced under Ohio Revised Code 3781.28.
