KISSS subsurface irrigation is the only irrigation system that effectivly waters oddly shaped greenroofs
Subsurface Capillary Irrigation (SCI) waters even fast draining green roof soils

KISSS (capillary irrigation subsurface systems), provide consistent coverage even in the most coarse green roof soils.  KISSS even applies fertilizer subsurface. This is a feature which just simply is not available with other irrigation systems including sprinklers and drip.

KISSS LEEDs the New Era in Quality and Water Conservation

KISSS provides many options for quality Green Roof, Eco Roof and Roof Garden irrigation including Below Flow Flat, Below Flow Wrap, Safety Flow and the Ebb and Flow MAT. These sub surface capillary irrigation systems provide complete even water application across an entire extensive or intensive green roof application. The Ebb and Flow Capillary Green Roof Mat provides an added bonus It acts as an active drainage layer through a capillary "wicking" process involving the combination of specialized geo-textile fibers, polyethylene plastics.

KISSS Capillary Irrigation Systems Are the Most Beneficial to All Greenroofs

CHALLENGES TO IRRIGATING GREEN ROOF SYSTEMS
A unique installation also presents unique irrigation challenges.  Below are some of the challenges to irrigating a green roof system.

ENGINEERED SOILS

Engineered soils for green roof systems are designed to drain quickly in the event of a heavy rainfall to prevent weight from building up on the roof.  For this reason conventional sprinkler irrigation and drip irrigation becomes problematic for eco roofs.  Neither system has the KISSS patented impermeable layer to stop the initial downward movement of water in these soils.  As with sandy soils, water moves straight down very quickly and must have a mechanism to slow the drainage.  Only KISSS offers this mechanism and has proven effective at achieving the soil moisture necessary to keep plants alive. 


HIGH WINDS

Rooftops provide a unique challenge in that they see greater wind speed than what is present at ground level.  A great example of this is the Target Center in Minneapolis, MN where the rooftop is 120 feet above street level.  High winds will render conventional sprinkler irrigation useless and cause tremendous amounts of waste and damage from overspray.
