Cracked Gully

[Mrxman]

We have slugs in our kitchen and I noticed slightly damp/moist earth under the suspended floorboards.
I am trying to get to the root cause and was wondering our gully outside could be the problem.
As you can see from the picture it's cracked here and there.

Any suggestions how to fix these cracks?
Do you think these cracks could be the cause of damp earth inside?

In a word....................Yes.

Dig out and replace.

O.k thanks.

So basically dig out and replace parts that are cracked?

Apart from that, is the construction/design of the gully o.k?

No - the whole lot needs removing and sorting out - that business with water discharging into glazed channel etc. is 19th Century - And a good candidate for damp

Thanks, that makes sense.
As it's currently a combined gully, I was thinking of connecting 2 floplast gullys to each other and have washing machine/gutter in one and two sink water pipes in the other.
Does that sound workable?

Strange how few pictures I've been able to find online of homeowners doing similar updates.

I fit these pretty often.

I use the Osma 4D900 and on yours I would use a single gully and alter the pipework to suit. Alternatively you could add a side inlet to it to pick up the 68mm pipe to the left of your pic.

Looks good. I noticed it has 2 closed boss sockets. Presumably you can cut one of them open to fit second waste pipe, is that right?
Then have storm water and washing machine at the top.

 

[Ian H]

That’s right but it’s very rare that we use the extra sockets. We just adjust the pipes to fit in the top of the gully.

- but make sure the waste pipes go through the grid and discharge above the water line. Storm pipe could go in side boss - as said by Ian above.
