Triple Sealed Manhole Covers

If you need an indoor manhole cover, our triple-sealed manhole covers are just what you need. With three sealing rings, they prevent unpleasant nuisance odours from escaping the drain into your living space. They can be filled with any flooring finish of your choosing, allowing you to maintain the required access without detracting from the property's finish. Available in a range of sizes and with ultra slim surrounds they have an exceptionally low impact visually.

About Triple Sealed Manhole Covers

Our range of manhole covers with triple seals is designed with three high-quality elasticated rubber seals built into the sides of the frame for the most demanding jobs, where maximum odour control, security, and water tightness are needed.

These covers deliver an extra layer of protection compared to double-sealed covers, providing access protection for both indoor and outdoor environments. They are ideal for urban infrastructure, industrial facilities, and areas that are prone to flooding, as well as public restrooms, changing rooms, and areas near bodies of water, where access points must be kept completely secure and immune to environmental effects.

In both private and public spaces, managing access to sewage and other utilities (like electricity and water), while preventing smells from escaping can be essential. By installing a triple-sealed manhole cover and frame, not only are there three strong barriers against escaping smells, but utilities are also triple-protected from the ingress of debris and water.

Available in a range of different materials, from lightweight aluminium to heavier-duty steel, triple-sealed manhole covers are durable, even in year-round British weather conditions, providing good resistance to corrosion and heavy footfall. With features like rubber seals for odour leaking, reinforcement mesh for added rigidity, and lifting keys included, our range performs well and facilitates easy use in the long term.

Recessed Triple Sealed Manhole Covers

Recessed manhole covers feature a hollow top, meaning they can be filled with paving materials (like stone, gravel, tiles or even wood), creating a finish that blends in with the surrounding area’s aesthetic. Because of this recessed design, these covers are perfect for installation in indoor and outdoor areas, like pedestrian areas and landscaped spaces, because of this recessed design. Once filled, this leaves a discreet access point that blends in visually with its surroundings.

Aluminium Covers

Aluminium manhole covers are designed to provide a lightweight barrier that is resistant to corrosion and other year-round wear. They are suitable for indoor and outdoor areas where a lightweight cover is preferred by workers. Our range of aluminium manhole covers often features slip-resistant surfaces and comes in a variety of different designs and sizes.

Getting The Best TripleSealed Manhole Cover For Your Needs

Consider the following factors when choosing the best triple-seal manhole cover for your needs:

Load-Bearing Capacity

It’s important to choose a cover with the correct load-bearing capacity for its intended installation environment and use case. Standard residential covers can generally support pedestrian and light vehicle traffic, while heavier-duty options can handle small utility vehicles. Make sure the cover meets the required loads to prevent damage to infrastructure and vehicles!

Ventilation & Odour Control

Consider a sealed cover in areas where odours may come up from the manhole cover, especially in kitchens or public areas like libraries or gardens. Our stock of double-sealed covers provides strong odour control, while our triple-sealed manhole covers are some of the strongest on the market!

Visual Coherence

For areas where appearance is important, consider a recessed manhole cover that can blend in with its surroundings.

Load-Bearing Capacity

It’s important to choose a cover that has the correct load bearing capacity for its intended use case and also has the correct slip-resistant surface. f. Standard residential covers can generally support pedestrian and light vehicle traffic, while heavier-duty options can handle small utility vehicles. Make sure the cover meets the required loads to prevent damage to infrastructure and vehicles!

Ease of Installation and Removal

The lightweight nature of plastic manhole covers makes them easier to handle compared to heavier materials. Most of our manhole covers come with lifting keys for ease of use, but consider the cover’s material and features for easier installation and use.

Security Features

Sometimes, it’s important to prevent access to the utilities below the manhole cover. Look for covers with locking mechanisms or tamper-resistant designs. These features are especially important in public areas and private properties where safety and security concerns are higher.

Slip Resistance

Depending on the style of manhole cover you choose, and its intended installation location, slip resistance can be an important safety feature, especially in high-footfall indoor public spaces. Choose a cover with slip-resistant features to reduce the likelihood of slips and falls, or consider a recessed manhole cover with contents that improve grip, especially in wet or icy conditions.
