Stormwater Management Solutions

Siplast stormwater management solutions are engineered to manage water at the source point – the roof. We understand that stormwater management requirements vary from region to region, and project to project. That's why we offer a variety of tools that can be seamlessly integrated into your ParaGREEN™ vegetated roof and amenity solutions. From extensive vegetated roofs addressing detention requirements to stormwater planters employed for passive irrigation, Siplast is your single-source provider of customized stormwater management solutions to meet your project's unique needs.

Purple Roof

Purple Roof Systems feature both detention and retention capacity to optimize stormwater management and are capable of turning extensive vegetated roofs into effective detention tools on both zero- and low-slope roofs.
Blue Green Roof Detention

Siplast Blue Green Roof Assemblies integrate a structural voiding unit beneath the vegetated roof assembly to create detention space, and are coupled with a flow control drain to slowly release water from the roof at a prescribed rate.
Blue Green Roof Retention (Passive Irrigation)

Siplast Blue Green Roof Retention Systems are designed to retain rainwater on a rooftop and release it slowly via capillary action so it can be accessed by plant material.
Blue Roof Paver

Siplast Blue Roof assembly employs the annular space created by the pedestals, between the membrane assembly and the bottom of the pavers, to detain stormwater until it can be released off the roof through a flow control drain.
