1 Fill pe M E. a M G P. General purpose non-shrink cementitious grout WHERE TO USE If Mapefill GP ME is prepared by only adding water, Recommended for grouting voids in structural it must be cured under damp conditions, in order to elements such as: honeycombs in concrete, guarantee that the product expansive properties filling gaps in precast elements, and grouting develop completely and correctly. base plates and bridge bearings. Please note that, in common with all other high quality cementitious based materials, curing of Some application examples Mapefill GP ME is essential under extreme and arid Anchoring of mechanical plant, and machinery. climatic conditions and/or where correct or adequate curing cannot be maintained, the addition of Anchorage of steel bolts and other metallic fixtures.

2 Mapecure SRA is highly recommended in order to ensure the required properties are attained. Filling of rigid joints between elements in concrete Mapecure SRA is considered a technologically and precast concrete structures. advanced additive system that has the capability of Underpinning works. slowing down the evaporation rate of the mixing water thereby promoting the development and Pressure grouting of concrete structures. effeciency of the hydration process. The addition of Mapecure SRA in proportions of upto has Grouting of machine baseplates. the ability to reduce drying shrinkage by between 20% and 50%. TECHNICAL CHARACTERISTICS. Mapefill GP ME is a preblended powdered grout Mapefill GP ME also has the following qualities: based on high strength cement, graded aggregates and special additives with an expansive agent excellent impermeability to water.

3 Formulated by the MAPEI research laboratories. When mixed with water Mapefill GP ME is excellent adhesion to rebar and concrete;. transformed into a highly fluid grout without segregation, able to fill intricate spaces. excellent resistance to mechanical stress;. Mapefill GP ME, due to its expansive agent, is modulus of elasticity and thermal expansion characterized by a total absence of shrinkage in the coefficient similar to those of high quality concrete;. plastic (ASTM C940) phase, and develops early flexural and compressive strength. non-toxic;.

Do not apply Mapefill GP ME at Mix only sufficient material that can be temperatures below +5 C. applied using available labour and equipment to ensure a continuous and APPLICATION PROCEDURE uninterrupted application. Preparing the substrate Remove all deteriorated concrete down After casting, Mapefill GP ME must be to sound substrate. properly cured; the surface of grout Scarify the surface and completely exposed to the air must be protected from eliminate dust, oil, grease, debris and rapid water evaporation that can cause the laitance.

5 Formation of surface cracks due to plastic Pre-soak the sides of the cavity or void shrinkage especially in hot and/or windy by filling with water. Before pouring, weather. ensure all excess water is removed. Ensure curing in accordance with good Use clean, compressed air if necessary. concrete practice. Spray water on surface exposed to air the Preparing the grout first 24 hours of curing or apply an anti- Pour up to 80% of the required mixing evaporant such as Mapecure E or water (see APPLICATION DATA) into a Mapecure S. clean, rust-free container and whilst mixing slowly add Mapefill GP ME continuously. Cleaning Add remaining water to achieve the desired Fresh grout can be removed from tools consistency. Mix for 1 to 2 minutes, scrape with water. After curing, cleaning becomes the sides of the mixing container to remove very difficult and can only be done any powder that is not well blended; remix mechanically.

According to the quantities to be prepared, Every 25 kg bag of Mapefill GP ME yields a grout mixer or a mechanical mixer can 13-14 litres of grout . be used paying careful attention to avoid the entraining of air bubbles. PACKAGING. Mixing by hand is not recommended. Mapefill GP ME is available in 25 kg bags. Do not use a free fall mixer. STORAGE. Application (anchoring) When stored in dry conditions in the Pour Mapefill GP ME from one side only in original, unopened bags, Mapefill GP ME. a continual flow encouraging the discharge has a shelf life of 12 months. If stored of air bubbles. at high temperature and or high humidity It is not necessary to vibrate the grout conditions the shelf life may be reduced. mechanically.
