American Hydrotech, the Chicago-based manufacturer of waterproofing and roofing products and a Sika subsidiary, announced on Tuesday that its Garden Roof Assemblies have successfully passed a series of tests to meet FM Approvals.
FM Approvals is a third-party testing and certification service like Underwriters Laboratories. In a Feb. 13 news release, American Hydrotech said receiving FM certification for its Garden Roof Assembly system provides building owners, architects, and landscape designers confidence when specifying a garden roof.
