For concrete that has spalled or lost its original profile, Mapegrout T40 helps rebuild the damaged section without the slump associated with flowing mortars. The thixotropic, fibre-reinforced mix is suited to properly prepared vertical and overhead repairs where the mortar needs to stay in place.
Do not use as a precision anchoring grout or on moving, contaminated or poorly prepared concrete. Repair thickness and reinforcement treatment depend on the defect.
What strength is Mapegrout T40?
Current MAPEI Australia data describes it as a 40MPa concrete repair mortar.
How thick can it be applied?
About 30–35mm per layer.
What is the typical consumption?
About 18.5kg/m² per centimetre of thickness.
Can it be used for anchoring?
No. Use a MAPEI anchoring grout for anchoring work.
