to cutting-edge sprayed
concrete on bridges
In its early years, CRL developed its own proprietary Cathite Repair System, using site-batched materials to deliver effective and reliable concrete repairs. As materials technology has advanced, this approach has evolved, and today all wet and dry sprayed concrete materials are factory-batched to ensure consistency, performance and quality control.
As members of the Sprayed Concrete Association (SCA), CRL has contributed to the development of the BS EN 1504 European Standard for the repair and protection of concrete. This standard is applied across all highways concrete repair and refurbishment projects, ensuring that solutions meet recognised best practice and regulatory requirements.

Repairs
On highways structures, the most common repair method is sprayed concrete (gunite) using pre-bagged, factory-controlled materials applied by either a wet or dry spray process. This method is particularly suitable for vertical and overhead surfaces and is widely used for structural repairs to bridges and other highway structures, as well as for sprayed overlays on ICCP systems.
In the dry spray process, materials are propelled through a hose using a pump, with water added at the nozzle. This process is controlled by a trained and experienced nozzleman, which is critical to achieving a successful repair.
Sprayed concrete provides high structural strength, excellent adhesion and rapid application, making it well suited to complex shapes or difficult-to-access locations. The high-velocity application ensures instant compaction, resulting in a durable repair. The system can also be combined with steel fibres to further increase strength.
