Composite Manhole Covers Tried and Tested from EJ

Composite manhole covers provide an exceptional utility and infrastructure solution in today's complex and challenging urban environments.

With expertise spanning 135 years, EJ has been on the forefront of designing, manufacturing, and distributing high-quality access solutions in over 140 different countries.

Driven by commitment to communities, EJ has developed a cutting-edge solution that promotes the highest level of safety and functionality to pedestrians, motorists, and utility workers - the composite manhole cover.

EJ composite manhole covers have the following advantages:

1. Composite manhole covers are secured and theft deterrent since composites have zero scrap value. There have been numerous commodity theft incidents, particularly manhole covers, recorded in some states. Open manhole covers create a dangerous hazard for pedestrians and motorists. This problem can cost local city councils hundreds, if not millions of dollars to replace lost manhole covers.

2. Composite manhole covers are made up of lightweight materials, which makes them easy to carry, transport, and install. EJ manhole covers weigh between 13 kg (56cm clear opening) and 34 kg (91cm clear opening). When manhole covers are situated in a frequently accessed areas, the reduced weight allows for easy access. Composite covers also improve the safety and welfare of workers since the reduced weight means fewer chances of straining to lift the manhole covers, therefore preventing the risk of back injury.

3. Composite manhole covers stay locked down in place. Manhole covers that have popped off due to faulty underground wiring, traffic vibration and road stress can cause problems and liabilities. The standard features of EJ covers include security locking to various levels by mechanical latch or bolting.

4. Composite manhole covers are made from non-corrosive materials that are suitable for a highly corrosive environment such as sewer, storm, and wastewater drainage systems. The structural integrity of EJ composite covers cannot be compromised.

5. Composite products do not conduct electricity, which is why composite manhole covers are ideal to use for power and telecommunication lines and in areas where stray voltage is a major concern. Heat transfer is also reduced when composites are used to cover a steam manhole.

6. Composite manhole covers have little to no interference with the wireless communication signals. This applies to water metering automation and electrical switching for smart grid technology.

7. Composite manhole covers may reduce the rate of inflow and infiltration of surface water in the sewer. Outdated manhole covers are loose-fitting, which allows excess water to the wastewater collection system. Tight-fitting composite manhole covers are manufactured to have tighter tolerance to surface water infiltration.

8. Composite manhole covers help reduce strong odours coming from the drainage system. The covers are produced with tight-fitting lids for better sealing when installed. Today, there are composite manhole risers, like EJ INFRA-RISER®, which maximises the fitting of the frame to the manhole structure.

9. Composite manhole covers provide cost-efficient and energy-saving solutions for local infrastructure.

10. All EJ products are designed and manufactured not just to meet, but to exceed specified loading requirements. Composite manhole covers are tested and have passed the Proof Load Testing (AS 3996) requirements.

Fuelled by continuous innovation, supported by state-of-the-art facilities and cutting edge technology - EJ casts their name and pride in their composite manhole cover products that will last for generations.
