1. Concrete Mix Designs

Working with the chosen concrete supplier, Metcon will tailor concrete mix designs to suit each project specification.

CEM1 or blended mixes with a range of aggregate sizes and slump characteristics are utilised depending on the design, location, timing and desired surface finish.

Mix designs will always be provided for approval before works on site commence.

2. Cube Tests

Where required, Metcon will take a set of 100x100mm concrete cubes per pour and have these independently crush tested to provide 7, 28 and 56 day test results.

Additional sets of cubes can be ordered to meet specification requirements.

3. Survey Results

 When required, Metcon will conduct a slab surface tolerance survey in accordance with the agreed specification on completion of each pour.

This consists of a straight edge survey in accordance with BS8204 whereby a calibrated two metre straight edge is placed perpendicular to the direction of the deck span and a calibrated wedge is used to measure the deviation beneath the straight edge and the surface of the slab.

The results are plotted on a layout drawing and issued as an ‘as built' survey.
