Mapei Mapefill GP is recommended for grouting voids in structural elements. These include items such as grouting base plates and bridge bearings, anchoring of steel bars, concrete repairs and filling gaps in precast elements.
Some application examples:
• Anchoring of mechanical equipments.
• 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.
Remove all deteriorated concrete down to a sound substrate. The substrate must be sound, clean, free of dust, grease, debris and laitance and sufficiently rough. 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.
Pour 80% of the required mixing water into a suitable rust free container and slowly add a 25 kg bag of MAPEFILL GP. Add the remaining water to achieve the desired mortar consistency (water ratios are 4 litres for ‘pumpable’ consistency; 4.5 for ‘pourable’ consistency). Mix for 1-2 minutes with a low speed mechanical mixer, then check that the mixture is well blended by removing any powder left on the sides of the mixer. Re-mix for another 2-3 minutes. Larger quantities can be mixed in a grout mixer.
The mix obtained remains workable for about 1 hour at +20°C.
Applying the grout
Pour the MAPEFILL GP mix from one side only into the prepared cavity or shutter in a continual flow in order to prevent the entrapment of air bubbles.
