Concrete disintegrating in back garden with pictures

[Mutley56]

I hope you can give me ideas concerning the followiing problem.

I have a concreted area immediately outside of the kitchen door that leads on the baack garden. The concrete is many years old, not sure how many but the house was built circa 80 years ago, and the surface is disintegrating. This gives rise to a continual layer of grit / dust that gets walked into the house.

I suspect that the concrete needs to be removed and replaced with another surface material but is there anything I can pour onto the surface to seal it or stabilise it in the short to medium term?

Thank you for looking at and responding to this post.

There are few thin coat products that will live past a good winter i,m afraid. You could, i suppose lay an inch of granite dust mixed with sharp sand and a good dose of cement and see how long this lasts, but would need to be a minimum 25mm thick.

The existing concrete surface would need to be clean and damped down just prior to laying. Also the muck would need to be semi-dry so that you can work a tight finish into the finished surface.

self leveling latex stuff?
sprinkle a handfull or three of grey stuff on top to match the colour in a bit?

Thanks for replying guys.

I've had self levelling compound used for internal floor work before, so I'll have to look into it for external work.

Ultimately, I guess I'll have to break the concrete up and put a new layer down. There is a soak away for the guttering downpipe in one corner of the concrete. Presumably the soak away should travel towards the garden and so I'd need to leave that conrner well alone to reduce the risk of damaging it.

Anyway, I'll do something about over the coming weeks, and if it turns out to be a good job then I'll post the outcome here.

Thanks again.
