Description

Medium strength (40 MPa) thixotropic mortar for the repair of concrete. Use Mapegrout T40 to repair damaged concrete surfaces such as balconies and corners of columns and beams. Mapegrout T40 is also recommended for repair work in tunnels, canals and water works in general. Mapegrout T40 can also be used to repair surfaces permanently in contact with drinking water. Mapegrout T40, mixed with about 16% water, forms a very workable mortar with a thixotropic consistency that is easily applied on vertical surfaces without shuttering. Mapegrout T40 is applied by trowel, float or plaster sprayer on damp supports that are solid and free of loose sections, which have previously been saturated with water. Repairs up to 30-35 mm thick in a single coat can be made.

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.

Uses

Repair of degraded vertical or horizontal concrete surfaces with mortar possessing medium mechanical performance characteristics.
