KYK MegaTamir İ Yapısal T103

R3 Class Structural Concrete Repair Mortar

Product Description

KYK MegaTamir İ Yapısal T103 is a cement-based structural repair mortar modified with polymers and reinforcing fibers, containing fine aggregates for superior application performance. Its high mechanical strength makes it an ideal solution for repairing structural weaknesses in reinforced concrete elements. Developed for professional applications, it provides durable, long-lasting concrete repairs.

Application Areas

Suitable for both interior and exterior applications, including:

  • Repair of reinforced concrete damaged by reinforcement corrosion
  • Structural surface restoration and levelling
  • Chamfer formation prior to waterproofing applications
  • Filling tie-rod holes and core drill openings
  • Creating durable, smooth substrates before finishing applications

For areas affected by reinforcement corrosion, it can be used as part of a complete repair system together with KYK MegaTamir T106.
