EFFC/DFI Best Practice Guide to Tremie Concrete for Deep Foundations
The EFFC/DFI Best Practice Guide to Tremie Concrete for Deep Foundations has been produced by a joint EFFC and DFI expert task group made up of consultants, contractors and concrete technical specialists from the industry.
The Guide provides state-of-the-art guidance on the acceptability criteria and placement of fresh concrete in bored piles and diaphragm walls, using Tremie methods. It has been produced to address the issues that have been encountered on site owing to the sensitivity of modern concrete mixes.
The Guide can be found here.

Concrete Cube Testing
Materials laboratories generally use their own format to report concrete test results. The contractor receiving the report, however, may deal with a number of laboratories, and therefore receives reports in a number of different formats. This can be confusing and time consuming, particularly if the raw data has to be manipulated or re-entered in order to transfer it to a database.
Additionally, laboratories may be asked by clients to customise the results, which can also be time consuming and less efficient. In order to streamline and make the process more efficient, the FPS have agreed with laboratories to trial a standard format. UKAS have confirmed that this is suitable for use by Registered Laboratories.
FPS Members have prepared the Excel spreadsheet based template and have agreed to use it unamended (to ensure that laboratories are not subject to variations). The FPS would welcome feedback from laboratories and contractors.
