Mapefill GP

General purpose non-shrink grout.

Available in a 25kg unit.

Technical Description

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.

Mapefill GP meets all the main requirements for ENV 1504-9 (“Products and systems for the protection and repair of concrete structures; definitions, requirements, quality control and conformity assessment. General principles for the use of products and systems”) and the minimum requirements for EN 1504-6 (“Anchoring steel
reinforcement”).

Areas of Use
