Ultimate Assembly Blue Roof

Void spaces that exist beneath concrete pavers in Hydrotech’s Ultimate Assembly can now be used to store large quantities of stormwater. Pavers are installed on pedestals in normal fashion but at an elevated height to generate the needed water storage volume. The paver weight is designed to keep the loose-laid STYROFOAM™ insulation from floating during those rain events when the blue roof is in operation. As a result, heavier, thicker pavers are typically required.

A rooftop terrace would be an ideal application for this blue roof assembly. Because the pedestals supporting the pavers are adjustable, this blue roof assembly may be ideal for roof decks with some roof slope where the goal is to create a level, paved finished surface.
