Mapegrid C170 High-Strength Carbon Fiber Mesh 10 x 10mm

Mapei MAPEGRID C170 – High-Strength Carbon Fibre Mesh for Structural Reinforcement

Mapei MAPEGRID C170 is a high-strength carbon-fibre mesh designed for the structural reinforcement of masonry and concrete structures. Its square mesh construction helps distribute mechanical stresses across reinforced surfaces, improving the ductility and structural performance of suitable building elements.

MAPEGRID C170 is used as part of Mapei's Fibre Reinforced Cementitious Matrix (FRCM) reinforcement systems. It is installed in combination with compatible Mapei mortars, including PLANITOP HDM MAXI and PLANITOP HDM RESTAURO, for strengthening stone, brick, tuff and concrete structures.

Key Benefits

• Manufactured from high-strength carbon fibres.
• High tensile strength with a lightweight construction.
• 10 × 10mm square mesh structure.
• Helps distribute stresses across reinforced masonry surfaces.
• Improves the ductility of suitably reinforced structures.
• Does not rust or corrode like conventional steel reinforcement.
• Resistant to chemical attack from cement-based materials.
• Good dimensional stability and durability within an inorganic mortar matrix.
• Easy to cut and adapt to the shape of the substrate.
• Suitable for compatible internal and external structural strengthening applications.

Typical Applications

MAPEGRID C170 is intended for reinforced structural strengthening of masonry and concrete structures. Typical applications include:

• Structural strengthening of stone masonry walls.
• Reinforcement of brick and tuff masonry.
• Strengthening of concrete structures.
• Seismic strengthening of masonry buildings.
• Reinforcement of masonry arches and vaulted structures.
• Strengthening the internal and external faces of suitable masonry elements.
• Restoration and structural improvement of existing buildings.
• Strengthening projects involving historic and traditional masonry construction.

Compatible Mapei Mortars

MAPEGRID C170 is installed in conjunction with compatible Mapei cementitious mortars. The manufacturer's documentation identifies the following products for the reinforcement system:

• PLANITOP HDM MAXI – two-component, high-ductility cementitious mortar.
• PLANITOP HDM RESTAURO – cementitious mortar for structural strengthening and restoration.

The selected mortar and reinforcement arrangement must be appropriate for the substrate and the intended structural application. Refer to the manufacturer's system documentation for the correct installation procedure.

Installation Overview

MAPEGRID C170 is embedded into a compatible fresh cementitious mortar as part of the Mapei reinforcement system. The substrate must be properly prepared to provide a sound, compact surface before installation.

• Remove deteriorated or detached render and loose material as required by the manufacturer's installation procedure.
• Prepare the masonry or concrete substrate to achieve a sound, suitably prepared surface.
• Apply the first layer of compatible mortar, generally around 5–6mm thick.
• Position MAPEGRID C170 into the fresh mortar and press it into place.
• Overlap adjacent mesh sections by at least 150mm in both directions.
• Apply a further layer of compatible mortar, generally around 5–6mm thick, to cover the mesh.
• Follow the manufacturer's instructions for any additional connectors, detailing and finishing requirements.

The installation procedure will depend on the structure and the selected reinforcement system. Structural design, mesh positioning, anchorage and detailing must be established by the appropriately qualified project designer.

Packaging and Storage

• Packaging: 1m wide × 50m long roll.
• Nominal roll area: 50m².
• Storage: Store in a covered, dry area.
• Product classification: Article; consult the manufacturer's handling guidance.

Important Product Information

MAPEGRID C170 is a reinforcement component and is not a standalone structural repair product. It must be installed with the compatible mortar and system components specified by Mapei.

Overlap requirements, substrate preparation, anchorage and installation details are important to the performance of the reinforcement system. Always follow the manufacturer's current technical documentation and the project-specific structural design.
