Mapegrout T40

A premixed powdered mortar composed of cement, graded aggregates and special additives. When mixed with water, Mapegrout T40 forms an easy to apply thixotropic mortar that can be applied without slumping even in substantial thicknesses on vertical surfaces without formwork.

Meets the requirements defined by BS EN 1504-9 and the minimum requirements claimed by BS EN 1504-3 for structural mortars of class R3.

Benefits:

• Moderate flexural and compressive strength.

• Has a modulus of elasticity, thermal expansion coefficient and permeability coefficient similar to that of medium quality concrete.

• Waterproof.

• Excellent adhesion to existing concrete surfaces provided they are saturated with water and reinforcing bars are first treated with Mapefer or Mapefer 1K.

Applications:

• Repair of degraded concrete surfaces, corners of pillars and beams, balconies damaged by rusted reinforcing bars.

• Repairs to diaphragms and tunnels.

• Concrete linings for canals and hydraulic projects.

• Reconstruction of concrete coverings of reinforcing bars.

• Repair of surface irregularities including exposed aggregate, joints between new and old concrete, holes in formwork concrete, protruding steel etc.

• Filling of rigid joints.
