Our participation at Vietbuild Vietnam has successfully concluded.
We were glad to meet numerous contractors, distributors and project partners face‑to‑face, discussing waterproofing membrane, slurry and related building material solutions for Southeast‑Asia tropical humid conditions.
We collected valuable market feedback for hot‑melt membrane, self‑adhesive membrane and negative‑side anti‑permeability slurry.
Thanks for every visitor who stopped by our booth for deep conversations.
