MAPEGROUT HI-FLOW TI 20: Steel Fiber-Reinforced, High-Ductility Flowable Concrete Repair Mortar
What is MAPEGROUT HI-FLOW TI 20?
MAPEGROUT HI-FLOW TI 20 is a specialized flowable concrete repair mortar reinforced with steel fibers and designed to provide high ductility. It offers outstanding resistance to impact, vibration, and crack formation, making it a reliable solution for structural repair applications.
Its cement-based, single-component formulation allows for easy preparation on-site. The shrinkage-controlled composition ensures dimensional stability, while the steel fiber reinforcement significantly enhances ductility. Compared to conventional repair mortars, it delivers superior strength and performance, particularly in reinforced concrete structures subjected to dynamic loads. The product is applied by form-and-pour methods and features self-compacting properties.

Application Instructions
Before application, the substrate must be cleaned of dust, oil, paint, and any contaminants that may impair adhesion. The surface should be damp but free from standing water.
Mix the product with the amount of water specified in the technical data sheet until a homogeneous, flowable consistency is achieved. Pour the mortar into the formwork, where it will spread under its own weight without the need for vibration. After application, the surface should be kept moist or protected with a suitable curing compound.
