Green Roofing Upgrades Atlanta Building

A $6-million roof rehab project using green roofing technology yields a state-of-the-art garden roof.
August 11, 2010

Strong design geometry combining a fully landscaped garden roof, outdoor dining terraces, two new 56-foot dome skylights, and a walkway connection to the office tower highlight the recently completed green roof renovation project at Atlanta's Northpark 500, leased and managed by CB Richard Ellis.


A complex re-roofing project replaces an Atlanta office facility’s roof with a green roofing system from American Hydrotech.
The 18-story building, built in 1989, is one of three buildings comprising Northpark Town Center, a mixed-use office complex located in Atlanta's Central Perimeter business district.

The $6-million rehabilitation project began with the demolition of the building's original green roof.

The building's original 56,000-square-foot green roof and 60-millimeter bituminous-type peel-and-stick waterproofing were removed and replaced with a waterproofing membrane combined with lightweight, low profile, green roof technology, all part of a Garden Roof Assembly supplied by American Hydrotech, Inc. Founded in 1977, American Hydrotech focuses on development, production and distribution of premium waterproofing, green roof technology and related construction products.

Thompson Ventulett Stainback & Associates, Atlanta, served as architect for the project. The roof's design, by Roy Ashley & Associates, Landscape Architects, Atlanta, addressed the need for top-notch watertight integrity and aesthetic allure by combining more than 59,000 square feet of Garden Roof Assembly in planters (precast separators) and 45,000 square feet of waterproofing and open joint pavers, all supplied by Hydrotech.

Waterproof Contractors, Inc. installed the waterproofing membrane and intensive Garden Roof Assembly. This included Hydrotech's Gardendrain, a specially engineered panel designed to provide drainage, retention and aeration to create a balance of air and water in the substrate soil, as well as to accommodate the wide variety of plants, shrubs and trees used in intensive green roof applications.
