concrete pads in wet ground

[ramon27]

Hi,

I know it is late now that it is done, but I still need some opinions on what I did and what to expect from it in future.

I am putting up DIY conservatory and I was suppose to make 5 concrete pads for base with dimensions 450x450mm and 450mm deep. I did just that, but what I started to be warried about is that I was pouring the concrete in very vet ground. Actually in two of the holes there was water about 2-3 inch deep which accumulated from soil around. I poured the concrete right in without taking the water out. The water was pushed out by the concrete and all looks good. But what I need to know - can the pads start to sink deeper after I put the conservatory up because it is durectly in soil? The soil was hard enough andfelt pretty compressed when I was digging.

What do you think?

Thanks for info...

Sorry but my interest waned a little when I read the five concrete pad thing.

Why have you not built a strip foundation particularly in view of the soft ground?

As for the bearing capacity of your ground - who knows? If you have dug down to a suitable depth i.e. removed all fertile stuff and have virgin, sub soil at say 700mm down then I don't see too much of a problem.

However, digging individual pads is more likely to yield evasive results.

It is for durabase, steel base, not standard brick walls. And it only requires 5 pads for the 'legs' of the steel base. It is approved way of building the conservatory base by approppriate authorities. I went for this option as it saves time and money. I hope I will have no problems with it...

I dug down to 450mm as was described by the base supplier and the soil was very solid, hard to dig at that depth already.
