FIELD TESTING

CET provides a comprehensive range of field testing services to the UK civil engineering industry, via our network of highly qualified engineers.

We provide a nationwide sampling and testing service; including strength testing using plate bearing and California Bearing Ratio CBR techniques, structural assessments, surveying of ground density; including traditional and non-destructive nuclear methods, paint and asbestos surveys.

Calling on years of in-depth technical knowledge and understanding, our teams take pride in consistently delivering high-quality field testing services that deliver against detailed contract specifications and standards.

On-site testing enables the certification of areas of construction, supporting continued placement and saving both time and money in the long-run.

Our field testing services enable our customers to meet and exceed their obligations, ensuring control and compliance on the most demanding of projects. We are happy to provide advice and guidance as to the most appropriate tests to ensure compliance and will recommend cost-effective, best-practice alternatives where applicable.

In Jan 2017 CET increased the scope of its on-site concrete testing services the adoption of new technologies and techniques has enabled us to carry out testing of high workability/ self-compacting testing.

Our scope now includes:

  • BS EN 12350-8 – Testing fresh concrete Part 8: Self-compacting concrete — Slump Flow test
  • BS EN 12350-9 – Testing fresh concrete Part 9: Self-compacting concrete — V Funnel test
  • BS EN 12350-10 – Testing fresh concrete Part 10: Self-compacting concrete — L Box test
  • BS EN 12350-11 – Testing fresh concrete Part 11: Self-compacting concrete — Sieve Segregation Test
  • BS EN 12350-12 – Testing fresh concrete Part 12: Self-compacting concrete — J Ring test
  • ASTM C232 – Standard Test Method For Bleeding Of Concrete
  • ASTM C1610 – Standard Test Method for Static Segregation of Self-Consolidating Concrete Using Column Technique
