Qmax is a slot drainage system for applications with all catchment area sizes. The one-piece bodies are manufactured from polyethylene, ensuring the system is light and robust. A variety of edge rails are available in galvanised steel and ductile iron to suit project requirements.
Qmax is available in 225, 350, 365, 465 and 600mm internal widths, and step connectors provide seamless connection between different sized systems to give the best hydraulic performance.
A patented pavement beam feature allows the steel reinforcement to continue through the inlet for an unbroken reinforced slab, and also allows service conduits to pass through. With this reinforcing the system is rated to EN1433 Class F900, which is comparable to load class G (AS3996).
