Waterfall ends?? not sure if I like them but here are a couple of concrete ones poured in situ.
Both in the process of finishing.

any update on what you did?

I notice in the bottom photo, where the grout is nice and smooth there is no mould.
One could possibly deduce that the grout is more of a problem than just…

Lilliana, a barrier is the objective.
and service life is a consideration(long required) so normally the spec would not be just a membrane ..and would also have a protective board of…

a liquid applied waterproofing membrane system

Not enough grinding, no grouting, no densifing and no polishing.
Why were they there?

Hey Emma, There are quite a few on this site if you do a search.
If I have time I will link a few threads hear.

you need a photo bucket host. there is a thread here about posting photos. Do a search and help will be at your finger tips

6banga . Ok a few things to discuss.
First It is highly unlikely the slab will be removed and as highly unlikely that would be necessary.
The faults we have seen suggest…

ps the safe went on it's side..

Sorry not to put a story up but I thought I'd give other people an opportunity to put up...
In view of the lack of response of a positive nature, several…

I can see what has happened on this occasion I can tell you exactly.
Pumps are funny things.

There is nothing funny about that job. No vibrator used and no concern for compaction. The mix is lumpy ie not homogeneously mixed.. Lazy

Yep, unfortunately there are SO many products on the market, it all becomes too confusing and 'people' revert back to the simplest way. Forgetting that the aesthetics are not really…

sorry I missed your post. How did you get on?

I'd have preferred to see so epoxy mortar, instead of concrete that will pop off next season.

All is quiet?? Slurry/grout so long as it goes hard and can be polished all is good.
Mostly people grout with the grindings and buffing from the piece, then you get…

A penetrating sealer binder will reduce if not stop moisture ingress, that in turn reduces salt ingressand the wet/dry cycle that has been happening for a very long time. Fretting…

A concrete scientist.... Hmmm would love to pick your brains about a few things. I've had a lot of fun with light weight and thin high strength concrete stuff.. A…

So ddarroch were you involved in the testing?...and integration of widespread use of fly ash and the re marketing a bit over ten years ago?

ddarroch in a previous life? I wonder if we have met? Who were you with? I've been around a few test labs, since a little way back circa 1981 was…

Seems everyone has been sold the message.
I disagree with a few points:
The strength, which has been compromised by the reduction of cement by 25-30%,
This also reduces the chance…

Just wondering how natural you want it and what the topography is like(beneficial) but then there is something like this: although not quite what I would call natural
and joins…

^^ and that too
Hmmm good question.
Two of my kids have recently had homes built and they also have chips off the corners of the render.
I asked why 'corner profiles' aren't…

That is pretty much my point. The mass of concrete causes shrinkage cracks if the (de)hydration is too rapid. ..they never go straight.
That was a very wet batch of concrete...…
