Project DescriptionDuradek solved a tricky waterproofing problem on this large roof terrace deck of a six storey concrete condominium in Kehei, Maui. The deck is just under 16,000 sq/ft and is used daily by the patrons to BBQ their dinners and enjoy the beautiful Hawaiian sunset.
Due to the high temperature roof environment, movement in the topping slab had resulted in frequent leaks into the 6th floor units and trapped moisture between coatings, topping slab and structural planks. Previous coatings had failed and would be cumbersome to replace. Complete removal of the existing roof membrane would be too risky if it were to rain, not to mention the additional cost that would incur.
To rectify the problem, large areas of failed coatings were scraped up; the deck was sanded with deck sanders and primed.
After these repairs were made, Duradek (a single-ply, waterproof, vinyl walkable membrane) was chosen to be applied right over top, making it watertight and attractive at the same time. When the material was to be ordered, the colors Duradek Heritage Sienna and Duradek Ultra Surcoseal Suede were chosen. These products were installed in a "window pane" pattern, using Suede for the frame and Sienna for the fields.
The owners are universally pleased, almost unheard of in large condo projects, and for the first time in 20 years there are absolutely no leaks.
