Mastic Jitra 229

The JITRA 229 sealant is used for the tightness of prefabricated concrete elements, for filter drains, under plates or corrugated sheets. It is also used as a filling sealant in annular spaces under compression.

Main advantage : 

  • Easy to implement
  • Good adhesion on concrete and steel surfaces
  • Excellent ageing behaviour : does not dry - does not harden
  • Excellent conformability to annular space under compression (complete filling of empty spaces)
  • Stable and inert to acid and base attacks
  • No toxicity and harm characteristics
