ULMA Architectural Solutions’ MultiV+150 and F250 polymer-concrete drainage channels were used in a construction project at the NBS Ādaži Military Base in Kadaga, Ādaži Municipality. The systems formed part of the site’s surface water management infrastructure, helping to collect and direct rainwater from paved and traffic areas.
The MultiV+150 system was applied in areas requiring a compact linear drainage solution suitable for medium hydraulic demands. Its 150 mm internal channel width, V-shaped profile and available grating options make it suitable for pedestrian, service and vehicle-access zones where reliable drainage and straightforward installation are required.
The F250 system was used where higher hydraulic capacity and stronger load-bearing performance were needed. As part of ULMA’s Civil F heavy-load range, it is designed for demanding areas exposed to heavier traffic or operational loads. Its 250 mm internal width and bolted grating-locking system provide a robust solution for technically demanding sections of the site.
The use of both systems allowed the drainage design to respond to different functional requirements across the project area. Together, the MultiV+150 and F250 channels supported controlled stormwater collection, durability and long-term maintainability within the military base infrastructure.
