Mapei 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 formulated by the MAPEI research laboratories. 

Recommended Use

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

Application examples

  • Anchoring of mechanical equipment.
  • 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.

Characteristics

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

Application Procedure

Technical Information For The Application

Mixing ratio:

Trowellable mix

Pumpable mix

Pourable mix

25 kg of Mapefill GP with 3.25-3.75 litres of water

25 kg of Mapefill GP with 3.75-4.25 litres of water

25 kg of Mapefill GP with 4.25-4.75 litres of water

Permitted application temperature:  Ambient and substrate temperature from +5°C to +40°C 
Pot life:  1 h (at +20°C)

Preparing the substrate

  • Remove all deteriorated concrete down to sound substrate.
  • Scarify the surface and eliminate completely dust, oil, grease, debris and laitance.
  • Soak the sides of the cavity to be filled with water. Before pouring, remove all excess water. To facilitate the elimination of unabsorbed water, use compressed air if necessary.

Preparing the grout

Pour up to 80% of the required water (see APPLICATION DATA) into a clean container and slowly add Mapefill GP continuously. Add remaining water to achieve the desired mix. Mix for 1 to 2 minutes with a heavy duty mixer, remove from the sides of the concrete mixer any powder that is not well blended; remix for another 2 to 3 minutes until a fluid homogeneous paste is obtained. According to the quantities to be prepared, a grout mixer or a mechanical mixer can be used paying careful attention to avoid the formation of air bubbles. Mixing by hand is not recommended.

Application (anchoring)

Pour Mapefill GP from one side only in a continual flow encouraging the discharge of air bubbles. The use of Mapefill GP for connecting precast concrete elements and the filling of rigid joints is recommended for thickness up to 6 cm. It is not necessary to vibrate the grout mechanically; to facilitate the filling of spaces that are particularly difficult, use a wood list or an iron rod.

Grouting of thick section

For filling cavities that have dimensions greater than those indicated, please consult our Technical Service for Assistance.
