Man hole

[diycooper]

Here is a picture of the man hole in my front.

What i need to know is i am going to pave it and i want to disguise the man hole with a man hole cover what you put the flags in.

What my question is i have enquired about a man hole cover and i can only get one the size of the metal lid which is 24 inch x 18 inch.

But i am going to take out the whole lot with the concrete as well as it is horrid.

How do i get around this as the chamber is the size of the concrete surrounding the cover.

Thx

go to somewhere like drain center (part of wolseley group) with your picture and the dimensions they should be able to get you a suitable hollow top one that you can set flag stones into
the chamber underneath is usually brick built and should allow for a slight variation in size of manhole cover
hope that helps

When i take the hole cover and surrounding out the hole is 3ft x 2ft.

Do you mean they might have man hole covers what you can put flags in that size?

Thx for fast reply.

You'll need to rebuild the masonary immediatly under the manhole but at a lower level if thats what you're asking? Have a look here: http://www.pavingexpert.com/drain05.htm

I can raise the chamber surrounding with engineering brick if i am correct, but how and can i reduce the hole size what you see when you take the surrounding off.

Sorry if i am confusing

Do i need to use a cover slab then build up then put man hole cover on?

Could i re use that concrete what i took out. By removng it knocking down three course then replacing that back down then build up with three layer of engineering brick to suit man hole cover.

Would that work you think?

 

[kevindgas]

the new cover should be of similar size but it will have a different top which you set the slabs into then it is just put onto the base frame which you slab up to on all sides
you just need to set the base to the height you need with sand/cement mix on top of bricks

 

[diycooper]

Is that concrete around the grid cover in my picture a cover slab?

 

[kevindgas]

the base part has an external lip which you cover with your flagstones

the inner or top part is recessed for the flags to go into it so creating a lid that is tiled with your flagstone of choice the lid is then put onto the base part and remains removable for access to the drain

Thx for help i understand now.

I was just thinking would it be possible to lower the original concrete what the lid is in now the build up to my required level what i need so that the new man hole cover fits?

 

[kevindgas]

yes - read the post 3 above !
