Sprayed concrete, also known as shotcrete, spray concrete or gunite, is a pneumatically applied concrete used to reinstate structural section, strengthen existing elements and repair large areas efficiently. Where hand-placed repair mortars become impractical due to scale, geometry or access, sprayed concrete is often the right technical and commercial answer.
CRS delivers sprayed concrete across the full range of applications used in the UK. Structural repair to bridges, retaining walls, tunnels and infrastructure. Concrete jacketing of columns and piers. Full-depth reinstatement of degraded or fire-damaged sections. Overlay of car park decks and industrial slabs. Face support in temporary and permanent applications. Both wet-mix and dry-mix processes are available depending on the specification, structure and access.
Materials are selected from approved system suppliers including Sika, Weber and Mapei, with sprayed concrete formulations designed for the application. Steel or synthetic fibre reinforcement is added where the design requires it. Bonding agents, primers and finishing systems are specified and applied to match the substrate condition and the intended service environment.
Sprayed concrete work is technique-sensitive. Nozzle distance, angle, application pressure and layer thickness all affect the finished quality. CRS operatives are trained to industry standards and the manufacturer’s system requirements, and every application is delivered to a written method statement with quality holds at agreed stages.
