4.3 Strip and trench fill foundations

Also see:

3.13.2

4.3.11 Concrete

Concrete for foundations shall be:

  1. of a mix which is suitable for the intended use
  2. durable against chemical or frost action
  3. correctly mixed, placed and cured.

Concreting should be carried out, as far as possible, in one operation, taking account of weather conditions and available daylight. Concrete should be placed as soon as possible after the excavation has been checked.

For trench fill foundations, it is particularly important to check that the finished level is correct and horizontal, as it is difficult to adjust for discrepancies in the small number of brick courses between the foundation and the DPC.
