Shrinkable soil map

[Ledburyjosh]

Hi, I am looking for an online resource, paid for or free to use, that allows you to find out the soil types in the area. I am sure I have found this before on the British Geological Survey website. Although I cant see it anymore.

 

Any help with this would be much appreciated. 

Thanks

BGS I think withdrew its online map site but replaced it with a slightly (Beta) better one.

 

Here's the one I use

Thank you

Do either of these give enough detail to determine whether those soils are shrinkable?

Good question to ask; not so easy to answer in full. Depends to some degree on what certainty you are seeking, how much risk you are willing to take & how much you are willing to pay. Furthermore, are you really interested in "soil" or what might be under the foundations of a building (i.e. possibly 50 cm, 1 metre or more under the surface i.e. geology)?

 

As Julian has pointed out BGS is going through a bit of a change both with online and app based information; whatever they provide is a crude assessment of mostly parent material. They also provide a site- based risk assessment report for which you need to pay - see below.

 

The soil database/mapping referred to is not designed to assess the presence of "shrinkable" soils. And its scale (as with BGS) will only give you the crudest means of assessing any particular site. 

 

If you have money I would simply ask BGS to provide you with a site based report on which you depend. It's not perfect but with suitable caveats it is what it is. Short of sampling the soils on site, probably not to an adequate depth, you won't do much better.

OK, thanks for the replies on this.

 

I know the site to be on free draining sandstone coupled with the trees being large mature trees at the time of building, tree-related subsidence is highly unlikely. For the purposes of what I have been asked a description of the soil type and any other observations will suffice.
