Plastic gulley lift higher

[kevhky]

Hi I'm laying new patio and I need to raise up this gulley to match the new level of the paving, I know that this is fitted into a pottery gully (sand/cement) that was broken when we moved in.

Will I need to somehow remove this gulley replacing it with a longer one or is there something else I can do.

Any advice will be great Thanks

If the gully is still broken under ground then this will need to be removed and replaced.

No it's not broken underground it was just the top what held the grate it was just chipped mire cosmetic than anything

Have you dug it up to look?

How old is it?

Where is the DPC in the wall, relative to your proposed new paving height?

Is that moss I can see growing in the wet brickwork?

It's not broke below the ground

The plastic gulley is around 10 year old

DPC is around 2ft at a guess above the new paving height

Back to the original question what is the best way to heighten it

Those plastic gullies and traps are sometimes made in one piece, but often in several pieces and you can add a vertical joiner. I think you will have to dig round it to see how it is made. With luck the top part will pull out.

Okay John Thanks I'll have a look

Older clay ones, however, are usually broken and need to be dug out.

Where is the break?
how much higher does it need to go?
You may well just be able to “stack” one on top of the old one so long as the actual plastic to terracotta is ok?

it might need care when stacking to get the levels right and some protection of the open areas if adding sand and cement

That was my exact thought about putting one on top of the other just remove the grate and run the other inside and mortar mix around to hold it in place
