Ballasted roof 2385 m² | Helsinki

At this site the apartment buildings are owened by Heka Oy - Helsinki City Housing Company. The roofs were coated with isocyanate-free ElaProof S.

Over the years, I have tested and widely used different thick-film waterproofing coatings. Based on these tests and experiences, today I recommend Elaproof as the primary product for waterproofing roofs. The cooperation with Build Care Oy has also been seamless and works in both directions.
