Standards and Specifications Guide

Product Types: One Standard, Consistent Performance

Primary, recycled, and manufactured aggregates are assessed against the same technical standards and specifications. Product origin does not change the compliance requirements – performance and suitability always come first.

Testing & Technical Data

All recycled aggregates are rigorously tested to comply with European Standards and national specifications, including the Specification for Highway Works (SHW).

  • Testing carried out by UKAS-accredited laboratories
  • Results available on request
  • Ongoing verification of declared performance

For quarried and dredged aggregates, we maintain a comprehensive technical data library from trusted third-party suppliers.

CE Marking & Declarations of Performance

Under the Construction Products Regulation (CPR), products covered by a Harmonised European Standard must be CE marked and supported by a Declaration of Performance (DoP).

Some highway materials, such as SHW Clause 803 Type 1 and 600 Series Capping, are not currently harmonised and therefore do not require CE marking.

Our technical team can confirm marking and documentation requirements for your specific application.

Factory Production Control (FPC)

  • Quality management systems
  • Inspection and monitoring routines
  • Testing and equipment calibration
  • Full production traceability and record-keeping

Built-in Quality Assurance

Factory Production Control is a permanent, audited system that ensures consistent product quality from raw material to dispatch.

Our FPC systems are audited against relevant BS EN standards and maintained as part of our ISO 9001:2015 certification. When a product is supported by FPC, its declared performance is continuously verified at source.
