What is Manhole Cover Replacement?
Before installing your replacement manhole cover, our team at Active Drainage will visit your property to take precise measurements of the opening. We’ll assess the width, depth, and height of the hole to ensure we find the perfect fit for your new cover.
Our experienced professionals will recommend the appropriate load class for your property, which indicates the maximum weight the manhole can safely support. For instance, if your manhole is located on a driveway, it’s essential to select a load class that can handle the weight of vehicles. In some cases, we may suggest manhole covers capable of withstanding heavier loads, such as delivery vans or lorries that might need to manoeuvre in your driveway.
Manhole covers are available in various materials, including aluminium, stainless steel, galvanized steel, and cast iron. We will guide you in selecting the best option for your manhole, considering factors such as durability, strength, and visual appeal.

Different Types Of Manhole Covers
Manhole covers come in various types and designs, each serving specific functions and requirements. Understanding the different types is essential for identifying when a replacement may be necessary.
- Cast Iron Manhole Covers: These are among the most common types due to their durability and strength. They can withstand heavy loads, making them ideal for roadways and driveways. However, they can rust over time, leading to deterioration and the need for replacement.
- Composite Manhole Covers: Made from a blend of materials, including fiberglass and resin, composite covers are lightweight and corrosion-resistant. They are often used in pedestrian areas and landscaped environments. However, they can be less durable under heavy traffic, leading to potential replacements.
- Plastic Manhole Covers: Lightweight and easy to install, plastic covers are often used in non-traffic areas like gardens or private properties. While they resist corrosion, they may not hold up well under heavy loads, necessitating replacement.
- Reinforced Concrete Covers: These heavy-duty covers are designed for high-traffic areas and can support substantial weight. While very durable, they can crack or chip over time, requiring eventual replacement.
Regular drain inspections are crucial to ensure manhole covers remain functional and safe. If you notice any signs of damage, such as rust, cracks, or misalignment, it’s essential to contact a professional for timely replacement.

FAQ
Frequently Asked Question
Who is responsible for replacing drain covers?
Responsibility for replacing drain covers typically falls on the property owner if the manhole is located on private property. For manholes in public roads or communal areas, the local council or utility company usually handles replacements and maintenance. It’s essential to check local regulations and guidelines to determine the specific responsibilities in your area.
Are manhole covers a standard size?
Manhole covers do come in various sizes, but there are common dimensions that many manufacturers follow. Standard sizes typically include 600mm x 600mm for rectangular covers and 750mm in diameter for circular covers. However, sizes can vary depending on the type of application, local regulations, and specific requirements, so it’s important to measure the opening accurately to ensure a proper fit.
How long do manhole covers last?
The lifespan of manhole covers can vary significantly based on material, usage, and environmental factors. Generally, well-maintained cast iron and reinforced concrete covers can last 30 years or more. However, covers made from lighter materials, such as plastic or aluminium, may have a shorter lifespan, typically ranging from 10 to 20 years.
Can you legally cover a manhole?
Legally covering a manhole is not advisable unless you have the appropriate permissions and it is compliant with local regulations. Manholes provide access for drain inspections of the sewer system, so obstructing them could create serious issues for public safety and utility services. Always consult with local authorities or utility companies before making any alterations to manholes or drainage systems.
