Mapei Mapefill GP – General Purpose Non-Shrink Grout
Mapefill GP is a pre-blended powdered grout based on high strength cement, graded aggregates with 1 mm diameter and special additives with an expansive agent.
When mixed with water Mapefill GP is transformed into a very highly fluid grout without segregation that is able to fill intricate spaces.
Recommended for grouting voids in structural elements such as: filling gaps in precast elements, and grouting base plates and bridge bearings and the following applications
- Anchoring of mechanical equipment and 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
Mapefill GP, due to its expansive agent, is characterised 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:
- initial set: 7 hours, final set: 8 hours
- 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
