TimberTech Pavers are subject to the same building codes as other pavers. These may include subbase grade, ratios between permeable and impermeable areas, easements, etc. When used to resurface decks, TimberTech has not been made aware of any code requirements or other required test reports (such as ICC-ES) as TimberTech Pavers are considered a “covering.” When used to resurface flat roofs, TimberTech Pavers have typically been considered “overburden” and not subject to specific fire or wind-uplift requirements. That said, TimberTech Pavers still maintain recommendations for installation in various wind-uplift situations like building height, parapet wall height, wind zone, etc. See our TimberTech Pavers Install Guide for more details. Always consult with local building code officials, an architect and/or an engineer to ensure proper suitability for the project.
