More Information on Plastic Manhole Covers:
Plastic chamber lids are the most commonly sold and found cover throughout the UK. This is due to their cheap cost, long working life span and ease of installation. There are a wide range of different types and sizes available.
They fit on the top of inspection chambers and typically they come in sizes from 320mm to 470mm, in round and square, and are usually secured to the top of the inspection chambers using screws and a rubber seal..
Different manufacturers of different manholes create their products in slightly different sizes, so not all of them are compatible. This means that if you're buying a replacement cover to fix a damaged or broken one you must make sure to measure the riser to make sure it's the correct size for the lid you're buying.
We stock two brands, Brett Martin and Kalsi Plastics. This is for the reasons mentioned above.
Brett Martin manufactures their risers in 315 and 450mm and their plastic chamber lids are made to fit these.
Whereas the Kalsi Plastics ones are manufactured to 320mm and 470mm, which is compatible with other brands such as Polypipe.
Obviously there are a wide range of manufacturers and a wide range of different sizes available on the market, so make sure to double check before ordering.
How Strong Are They? Are they for domestic use only?
Polypropylene manhole lids have a load rating of 3.5kn. This is rated high enough for foot traffic, lawnmowers, slow-moving cars, bikes etc.
However, they should be used domestically and not anywhere with large vehicles or heavy traffic.
What are they made from?
Polypropylene, which is a lightweight, low-cost material perfect for plastic covers. It's also a relatively low-cost material, meaning these covers are usually the most economical due to the light weight making things like free delivery a possibility, but these features also make them the easiest to install.
Polypropylene covers are made via injection moulding machines, these machines inject molten plastic into a mould which then cools to form the required shape and dimensions of the lid and frame.
Cover and frames and made from a wide range of materials, however this material offers several advantages over alternatives such as cast iron or galvanised steel, for the reasons listed above, however cast iron is a stronger, heavier material and cast iron can usually withstand a larger load.
Are they sealed will any smells leak out, can I use it inside a building?
They are single sealed, which will help to reduce any smells from escaping from the manhole. However, a double-sealed cover will be required if used inside a building.
How do I fit it, any tips?
Presuming the correctly sized lid has been chosen for the riser. You'll simply need to lubricate the seal using pipe lubricant, then push the lid onto the top of the riser for a snug fit. Then using the screws provided you can fix the lid down to the frame. Now the inspection chamber should be properly sealed and the lid fully installed.
What tools will I need to fit them?
Only basic tools will be required. A Philips or flat-head screwdriver, and some pipe lubricant to apply onto the riser and the lid to ensure a tight fit. You'll also require a tape measure to measure the diameter of the riser so that the correct lid is purchased.
