PUMPABLE, MULTI-PURPOSE, SHRINKAGE-COMPENSATED, CEMENTITIOUS GROUT
Description
Mapefill 318 is a preblended powdered grout composed of high strength cement, graded 1.2 mm aggregates and special additives with expansion agents formulated by the MAPEI research laboratories. When mixed with water, Mapefill 318 is transformed into a highly fluid grout with good pumping properties that able to fill narrow, intricate spaces without segregation. Mapefill 318, due to its dual-stage expansion, is characterized by a total absence of shrinkage in the plastic and hardening phases, and develops very high early flexural and compressive strengths.
