Problem addressed

In view of the potential threats of fire accidents and to provide superior waterproof function to buildings, NAMI has used advanced composite technology to develop a fireproof, smokeproof and waterproof system for module-to-module connection joints in MiC.

  • The system comprises a next-generation backing material with heat resistance of over 800℃.
  • It also consists of a durable sealant with over 700% elongation to accommodate ±50% module movement.
  • The system also contains a brushable waterproof coating with over 400% fracture elongation and 50m water pressure resistance.
Key impact
  • Seamless, eliminating the possibility of joint failure through poor workmanship
  • Easy to install and fits in corners, fitting into small spaces
  • Excellent weathering resistance and superior waterproofing performance
  • MiC: module-to-module connection joints, module to core wall connection joints, roof and fire water tank, etc.
  • Building: celling, balcony, swimming pool, fire water tank, external wall, roof, roof garden, etc.
  • Infrastructure: tunnels, bridges, underground buildings, etc.
