Hi Everyone,
For the last few weeks I have been reading a lot of your posts and I would firstly like to thank all you experts who give up your valuable time to help others.
My first self-build project for next year is a single storey rear extension (approx. 2m out by 5m wide).
Untill I begin this project I will be asking for some advice, that is if I can not find the answer in a previous post.
So for now, my first question is regarding building in the frost-level (which I have learned is below DPC + 225mm below Ground Level).
Which of the following are suitable to be used for the outer leaf within the frost-level :-
1. Concrete foundation (ready-mix)
2. Dense Concrete Block 7N
3. Trench Block 3.6N (300mm)
I have read some posts which have touched on this subject, so I am already aware that Blues, Class B Eng are ok but I would be grateful for some more clarification on the above products.
Many thanks.
