For the repair of concrete, stone and masonry structures, where low dust emission and low rebound is required. Mapegrout Gunite FSD complies with the Highways England specification for repairs to highway structures. Some application examples · Repair of concrete lining in road/rail/subway tunnels. · Fast support during excavation for D&B, hard rock TBMs and foundations. · Covering stone or masonry in tunnels. · Repair of damaged bridges. · Repair of hydraulic works such as canals, tunnels, reservoirs, etc. · Repair of industrial concrete structures.


Mapegrout Gunite FSD is a one-component ready-mixed cementitious mortar composed of hydraulic binders, silica fume, selected aggregate and special additives manufactured according to a formulation developed in the MAPEI research laboratories. When mixed with water, Mapegrout Gunite FSD acquires a thixotropic consistency and can therefore be easily applied on vertical and overhead surfaces in substantial thickness. The hardening process starts very early after the application, in order to improve: · speed of application (several layers in a shorter time); · safety during operation: manpower and equipment can move under the same area in shorter time if compared to standard mortars. After hardening, Mapegrout Gunite FSD: · has high flexural and compressive strength; · is watertight; · adheres very strongly to old concrete, provided the concrete is first saturated with water, and to reinforcement bars, especially when they are first treated with Mapefer or Mapefer 1K; · resists sulphates; · resists carbonation; Mapegrout Gunite FSD meets all the main principles of EN 1504-9 (“Products and systems for the protection and repair of concrete structures: definitions, requirements, quality control and conformity assessment.
