Triple Sealed Manhole Covers

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.
