7 Risks of Uncovered Core Holes in Streets
Share
Core drilling is a routine necessity for utility locating, pavement testing, and infrastructure inspections. But once the drill bit comes up, a new challenge begins: managing the 8-inch hazard left behind in the roadway.
In a busy travel lane, an uncovered core hole is a ticking clock of liability. From shredding passenger tires to snagging snowplow blades, the consequences of 'leaving it for later' can result in expensive claims and project delays.
Here is why securing your street-level core holes immediately is the smartest move for your crew and your bottom line.
1. Vehicle Damage and Flat Tire Claims
An 8-inch core hole in a travel lane is a tire-swallowing hazard with perfectly sharp edges that can shred a sidewall or crack a rim instantly.
- Tire blowouts: Low-profile tires on passenger vehicles or motorcycles can easily be pinched or blown out by an open core.
- Rim damage: The vertical drop of a core hole is the perfect depth to bend a rim, leading to costly claims against the city or contractor.
2. The “Snowplow Factor”
In northern climates, traditional “temporary” fixes like asphalt cold-patch or loose steel plates fail when the snowplows come out.
- Blade snags: An 8-inch open hole or poorly secured cover can catch a plow blade, damaging the equipment and the surrounding pavement.
- Corx solution: Because the core plate hole cover from Corx sits flush and secures tightly, plows glide right over them without dislodging the cover or damaging the blade.
3. Pedestrian and Cyclist Safety (The ADA Factor)
Core holes in crosswalks or bike lanes are catastrophic hazards for cyclists or scooters.
- Cyclists: A narrow bike tire falling into a core hole results in an immediate “over-the-handlebars” crash.
- Trip hazards: For pedestrians, especially those with mobility aids or heels, an open hole is a direct violation of safe-pathway standards.
4. Preventing “Rework” from debris infill
In street work, you often need to return to that hole to inspect or fill it later.
- If left open, the hole fills with road salt, gravel, and trash.
- Cleaning out a “clogged” core hole before final patching adds unnecessary man-hours.
5. High-Visibility for Nighttime Traffic
Street work often happens in low-light conditions.
- A dark hole in grey asphalt is invisible at 35 mph.
- Using a high-visibility (orange/yellow) cover alerts drivers and workers to the hazard before they are on top of it.

While a cold patch is often the ‘default’ fix, the labor costs and risk of snowplow damage make it the most expensive option in the long run. Corx provides a one-and-done solution.
