HERMEQ’s plastic hole covers are engineered to quickly seal and secure temporary floor openings on construction sites. These 350mm x 350mm square covers are designed to fit 300mm diameter holes precisely. With a low-profile design and high-visibility finish, each hole cover provides clear, anti-slip protection over voids without introducing trip hazards.
Unlike makeshift timber boards, these purpose-built hole covers offer a professional, durable, and safer alternative for covering service holes, drains, or maintenance voids. Installed using four corner screw fixings, they stay firmly in place during ongoing work and foot traffic.
- Non-slip hole cover surface – Moulded pattern improves grip in wet or dusty conditions.
- Fast deployment – Covers can be installed or removed in seconds with screws.
- Reusable site safety gear – Made from sustainable polypropylene plastic.
- Vivid yellow finish – High visibility for safety indoors and on live sites.
- Compatible with 300mm voids – No trimming required; ready to install on delivery.
These lightweight but strong covers are ideal for commercial fit-outs, infrastructure works, and service maintenance operations. Their clean, professional appearance and anti-bacterial properties make them suitable for hygienic interior spaces as well as active build zones. The bright yellow colouring acts as a warning while calming movement on site with their stable, flush-mounted design.
HERMEQ stock a wide range of Ground Mats, Bog Mats, Trench Covers & Road Plates conforming to all required safety specifications and regulations.

Supplied flat-packed and ready to install, these hole covers are suited to high-traffic internal construction areas where frequent hole access may be required. Reusability and cleanliness make them an excellent addition to health-conscious projects. With no need for cutting or shaping, they support lean install processes on site, and their anti-slip texture supports confident footing for workers and trades.
Whether used across voids in office blocks, service shafts or core drilling gaps, these covers offer rapid protection that aligns with best-practice site safety protocols. For added peace of mind, each hole cover is supported by test data confirming its capability under working conditions.
