The HERMEQ Temporary Manhole Cover is a purpose-built hole cover system that eliminates the need for steel plates or timber boards during active construction and groundworks projects. Sized at 750mm x 750mm x 79mm, it covers exposed manholes and surface voids with a reusable, anti-slip, and safety-optimised design. Unlike makeshift plywood or steel covers, it is light enough for one-person installation, yet strong enough to carry 4-tonne site traffic loads.

Built from industrial-grade Nylon 6 and fitted with a spring-loaded alloy steel locking mechanism, the cover remains secured in place under heavy loads, vibration, and frequent crossings. This makes it ideal for construction sites, civil engineering zones and utility works where exposed manhole slabs or core drilling holes pose both safety and access hazards.

Reliable hole covers solution – Seals open access points up to 750mm across.
Safe and simple to deploy – Drop into place and lock using supplied key.
Replaces unsafe timber hole cover practices – Engineered to prevent falls and ingress.
Stronger than standard manhole covers – Withstands 4T loads with elastic deformation safety.
Ideal for temporary reinstatement – Reusable for repeat installations across projects.

This innovative alternative to traditional manhole covers ensures site efficiency and H&S compliance while drastically cutting lifting risk. The rotating steel interlock holds the cover in place until released with the included key. Built to BS EN 124:1994 testing standards, the cover is fatigue-resistant and resilient against repeated impacts, ensuring it retains shape and load-bearing integrity over time.

Contractors benefit from quicker installs, reduced material waste, and improved safety outcomes compared to temporary boarding, surface barriers or costly steel manhole cover plates. A simple and effective way to maintain surface access while keeping hazardous voids safely sealed.

HERMEQ stock a wide-range of Ground Mats, Bog Mats, Trench Covers & Road Plates conforming to all required safety specifications and regulations.

This temporary hole cover is ideal for general contractors, civil engineers, and public works crews who require a cost-effective and reusable way to seal voids between active service phases. It eliminates the need for manual lifting gear and reduces downtime associated with placing and removing traditional manhole covers or boards.

By allowing site vehicles to pass directly over covered manholes without routing detours, the HERMEQ cover enhances site flow and safety at the same time. It’s particularly suited for use on reinstatement jobs, roadworks, or construction pads where trenching or duct installation leaves exposed holes needing secure coverage.
