Additional Details

When Gap Inc. decided to build their first company owned office building, they wanted the facility to embody the company's commitment to the environment. By incorporating a green roof into the design of 901 Cherry, the architects dramatically improved the building’s energy efficiency
and reduced the demand on local storm sewers. In addition, the presence of native grasses and wildflowers on the roof helps the building blend with the surrounding landscape.

Unlike a traditional roof, a green roof is designed to retain water, placing added importance on the impenetrability of the roofing membrane. By specifying MM6125®, the design team selected a membrane know for its watertight integrity and ability to perform even under submersed conditions. Fluid applied and flexible, MM6125 readily conformed to the undulating surface of the building’s roof deck. And because the membrane is fully adhered to the deck and has no seams, there is little risk of having to remove soil and plants to track a leak. MM6125 is also resistant to fertilizers and most acids.

In addition to 901 Cherry, Hydrotech has supplied materials for earth covered facilities worldwide. And now, through the introduction of the Garden Roof®, a green roof system developed by Hydrotech, building owners and design professionals can transform any new or existing roof into a landscaped environment.
