Can waterproofing materials be used with all Oatey commercial drains?
No. Waterproofing materials can only be applied in series with our flanged drain assemblies. Please visit our website to select the right drain for your project.
How should a Roof Drain be installed when foam insulation is installed on the roof?
The roof drain should always be set onto the base of the roof structure unless otherwise specified by a roofing materials manufacture or project engineer. After the drain is secured into place using the Underdeck Clamp Kit, the roof would then be flashed (waterproofed). The insulation, other roofing materials and finishes are set into place according to the roofing materials manufacturer or the project engineer.
