HANA Building Materials Trading L.L.C applies membrane and liquid-applied waterproofing systems for roofs, terraces, walkways and wet areas — designed to stop leaks before they start and protect the structure underneath. Our crews handle surface preparation, membrane or coating application, and detailing around joints, drains and railings.
We work on everything from a single rooftop walkway to full building terraces, using systems matched to the exposure conditions and expected foot or vehicle traffic.
