Frequently Asked Questions

The Corx Core Plate Hole Cover is designed specifically for 8-inch core holes. Using the correct size ensures a proper fit and helps the cover stay securely in place. A 6-inch core hole cover is in the works and will be available in the near future.

Yes. Open core holes create a clear trip and injury hazard on active job sites. Covering core holes helps protect workers, visitors, and inspectors from accidental step-ins, twisted ankles, or falls. Even shallow holes can cause serious injuries if left exposed.

If left open on the street, it can impact the safety of bicyclists, joggers, and tires on vehicles. Discover risks of liability for an open hole.

The safety orange color of Corx assists the concrete/asphalt crews to find the core holes for filling (as they typically follow the utility contractor), as well as alerting municipal agencies (i.e. city managers/Quality Assurance agents) to where holes remain to be filled.

Corx hole covers are commonly used by concrete contractors, directional drilling crews, utility contractors, and facility engineers/managers who want a fast, simple way to reduce job-site hazards caused by open core holes.

Corx is made from HDPE (High-Density Polyethylene) for durability and for all seasons. Learn more about this product.

Yes. Corx Hole Covers are made from durable materials and can be reused across multiple projects as long as they remain in good condition and fit securely in the hole.

Any drilled opening in a walking or working surface that a person could step into should be covered. Core holes — especially those created during concrete drilling — are common hazards because they are circular, easy to miss, and often located in high-traffic areas.

Core holes should be covered immediately after drilling is complete. Leaving holes uncovered, even temporarily, increases the risk of accidents as crews move around the site. Corx Hole Covers are designed to be placed quickly so safety isn’t delayed.

Makeshift materials like cardboard or loose plywood are unreliable and can shift, break, or go unnoticed. Purpose-built hole covers are designed to fit securely, remain visible, and reduce the risk of failure compared to improvised solutions.

No. The Corx Core Plate Hole Cover is a simple drop-in solution. It installs by placing it directly into the core hole — no tools, anchors, or hardware required. This makes it easy to use immediately after drilling.

Any surface that may be exposed to foot traffic or equipment should be evaluated carefully. While Corx covers help reduce trip hazards, users should always assess site conditions and traffic patterns to determine appropriate placement and use.

Uncovered holes are a known job-site hazard. Covering them demonstrates proactive safety practices and helps reduce the risk of accidents that can lead to injury claims, insurance issues, or work stoppages.

Yes. Hole covers should be inspected periodically to ensure they are not cracked, damaged, or loose. If a cover no longer fits securely or shows signs of wear, it should be replaced.

Corx Hole Covers are intended as a temporary safety solution for open core holes during construction or renovation. Permanent repairs or infill should be completed according to project requirements once work is finished.
