PRODUCT DESCRIPTION: BuMaFill is a preblended non-shrink, cementitious grout based on high strength cement, graded aggregates, silicafume with an expansive agent formulated by BUMATECH research laboratories. With a special blend of shrinkage - reducing and superplasticizer/ water-reducing agent, BuMaFill compensates for shrinkage in both the plastic and hardened states, and develops early flexural and compressive strength.

USES

  • For structural grouting of column base plates, machine base plates, anchor rods, bearing plates, precast wall panel, curtain walls
  • Multiple fluidity allows easy of placement : Ram in place as a dry pack, trowel apply as a medium flow, pour or pump as a high flow
  • For grouting method of concrete repair.
  • Filling of rigid joints between elements in concrete and precast concrete structures.
  • Anchoring of mechanical equipment
