Mapefill GP is a preblended powdered grout based on high strength cement, graded aggregates with 1 mm diameter and special additives with an expansive agent formulated by the MAPEI research laboratories. When mixed with water Mapefill GP is transformed into a very highly fluid grout without segregation that is able to fill intricate spaces. Mapefill GP, due to its expansive agent, is characterized by a total absence of shrinkage in the plastic (ASTM C827) and hardened phase, and develops early flexural and compressive strength. Mapefill GP also has the following qualities:

• Excellent impermeability to water;
• Excellent adhesion to iron and concrete;
• Excellent resistance to dynamic mechanical stress;
• Modulus of elasticity and thermal expansion coefficient similar to those of high quality concrete;
• Mapefill GP does not contain metal aggregates and aluminium dust;
• Non-toxic;
• Non-corrosive;
• Chloride-free.

Applications

• Anchoring of mechanical equipments.
• Anchoring of steel bars.
• Filling of rigid joints between elements in concrete and precast concrete structures.
• Execution of underpinning.
• Pressure grouting of concrete structures.
• Grouting of machine baseplate, bridge bearing.
• Concrete repairs.

Recommended for grouting voids in structural elements such as: patching up honeycombs in concrete, filling gaps in precast elements, and grouting base plates and bridge bearings.
