Heavy duty manhole covers are simply removable plates that form a lid over the manhole. The main purpose of the heavy duty manhole covers is to restrict unauthorised access and to prevent anything falling in the manhole. Typically, a manhole cover will be found on driveways or pavements to prevent any dangers.

The heavy duty manhole covers that we provide at Build Plumb Plastics are designed to suit any areas of heavy or regular traffic and each complies with British Standards. Our products are designed and manufactured in the UK and include reputable brands like Clark Drain.

We supply the heavy duty manhole frames too; these are suitable for various loading capacities and protect manholes. Within our collection of heavy duty covers and frames, you’ll discover the manhole chamber reducer ring, amongst many other products. The reducer ring is made from black polypropylene and reduces the opening of the manhole- it’s also ideal for new and existing installations.

The heavy duty manhole covers are hinged, making it easier to lift the plate for inspection. Here at Build Plumb Plastics, we supply the lifting keys for medium and heavy duty manhole covers, allowing you to lift the lid with ease and to carry out regular servicing and maintenance.

Any heavy duty manhole frames and covers are prone to several impacts; therefore, they need to be able to withstand these, without compromising safety standards. Our heavy duty manhole frames and covers incorporate an anti-slip tread meaning that they are safe to use (which is ideal if they are placed on pavements.)

Here at Build Plumb Plastics, we also supply the Clark Drain CLKS1657 heavy duty manhole cover and frame which is made from cast iron. Grey in colour, with a black polypropylene frame, this heavy duty manhole cover is perfect for pedestrianised areas and is compatible with many other accessories.

To avoid choosing the wrong size covers and frames, take into consideration the exact requirements of the manhole. By choosing the right size products, you’ll get more out of them.

What Types Of Manhole Covers Are There?

There are several types of manhole covers, including cast iron, ductile iron, steel, and composite materials. Cast iron covers are the most common and are known for their durability and strength. Ductile iron covers are similar to cast iron but are more flexible and resistant to cracking. Steel covers are lightweight and easy to install, but they are not as durable as cast iron or ductile iron. Composite covers are made from a combination of materials and are often used in areas where theft is a concern.

What Size Manhole Cover Do I Need?

The size of the manhole cover you need will depend on the size of the manhole opening. Measure the diameter of the opening and choose a cover that is slightly larger to ensure a secure fit. It is important to choose a cover that meets the weight requirements for the area where it will be installed.

Can I fit a square manhole cover into a round chamber?

It depends on the size and dimensions of the manhole cover and chamber. It is possible to fit a square manhole cover into a round chamber with the use of adapters or by modifying the chamber to fit the cover. However, it is important to ensure that the cover fits securely and does not pose a safety hazard. It is recommended to consult with a professional or manufacturer for guidance on proper installation.

How can plastic manholes be adapted to the final height of the pavement?

One solution is to use adjustable plastic manhole risers that can be easily cut to the desired height and then secured in place with screws. Another option is to use a leveling compound to create a smooth surface around the manhole and bring it up to the desired height. It is important to ensure that the manhole cover is flush with the pavement to prevent tripping hazards and damage to vehicles.

How can plastic manholes withstand traffic loads?

Plastics manholes are designed to withstand traffic loads through a combination of factors. They are made from high-density polyethylene (HDPE) or polypropylene (PP) materials that are strong and durable. The manholes are also designed with ribbing and other structural features that distribute the weight of the traffic load evenly across the surface of the manhole. Additionally, plastic manholes are resistant to corrosion, which helps to ensure their longevity and ability to withstand heavy traffic loads over time.
