Grid gutter Prefaest RI, self-supporting type I
RI® line drainage channels have been the most sustainable solution for drainage projects for years.
Self-supporting RI grid channels from Stradal
Stradal's self-supporting RI grid channels (self-supporting drainage channels) are marketed in the Netherlands by Diederen Afwateringstechniek. A self-supporting line drainage, fitted with a cast iron "Ondine" profile grating class D, 400KN or F, 900KN.
RI ® linear drainage channels, with a standard width of 100 mm, are a sustainable solution where drainage and rapid cleaning must go hand in hand. A C60/75 concrete quality and reinforcement in longitudinal and transverse direction make up this system
self-standing, making a concrete support back superfluous in every traffic class. Because it is nodular cast iron
grille is clamped in the galvanized steel rebate in a durable way, the grille can be opened quickly,
after which the gutter can be easily cleaned. Corner solution elements, end outlets and sand trap elements belong
to the standard delivery program. If high demands are made on the quality of the gutter within a project, such as
in industrial areas, public roads and environmental stations, the RI ® drainage channel can be used without any problems.
RI® gutters are provided with pre-assembled, specially developed, nodular cast iron grids. The profile ensures an optimal and fast absorption of water. The RI® gutters are also equipped with a stem/nut end. Thanks to the prepared sealant joint, it is possible to have a liquid-tight finish between the elements.
