ULMA drainage channels are among the most respected linear drainage systems in Europe, manufactured in polymer concrete to exacting standards and trusted on projects from private gardens to international airports. For specifiers in the Baltics and Finland, the appeal is twofold: a comprehensive, well-engineered product range, and local availability through an authorised distributor who understands the regional climate and the demands of each application.
A Range for Every Application
The breadth of the ULMA drainage channels family is what makes them so widely specified. At the lighter end, the Mini and Self ranges suit gardens, patios and pedestrian areas, with compact bodies and attractive composite gratings. Civil-S and Civil-F cover the broad middle ground of public realm, commercial and lightly trafficked schemes, while KompaqDrain and MultiV+ step up to roads, yards and heavy infrastructure.
For the most demanding settings there are specialist lines: KompaqSlot delivers discreet, high-capacity slot drainage; the Hydro and Urban ranges address larger-volume and public realm needs; Sport caters for sports facilities and pool surrounds; and RapidSelf offers quick, adaptable installation. Across all of them, ULMA drainage channels share the same polymer concrete core — dense, non-porous and resistant to frost, salts and chemicals — paired with composite, galvanised steel or ductile iron gratings to suit the load.
Load Classes and Performance
Every system in the range is rated to the EN 1433 standard, spanning all six load classes from A15 for pedestrian areas to F900 for ports and airfields. Because ULMA tests channel and grating together, the certified class is genuinely achieved in the finished surface rather than assumed. This matters across Estonia, Latvia, Lithuania and Finland, where freeze-thaw cycles and de-icing salts punish anything less than a properly engineered, frost-resistant product. The class number itself reflects a test load in kilonewtons, so stepping up from C250 to D400, or from D400 to F900, represents a real and verified increase in capability rather than a marketing label.
Hydraulically, the smooth polymer concrete bore and carefully designed falls keep water moving at self-cleaning velocity, reducing silt build-up and maintenance over the life of the installation. Whether the priority is capacity, appearance, chemical resistance or sheer strength, there is a configuration to match — which is precisely why architects and engineers across the region return to the range project after project, confident that a familiar system will behave predictably on site.
Local Supply Through Vesmaco
A great product is only useful if you can get it, with advice, when you need it. Vesmaco OÜ is the authorised ULMA distributor for Estonia, Latvia, Lithuania and Finland, holding local stock of the popular ranges and channelling factory support to regional projects. That means shorter lead times, guidance grounded in the local climate, and a single point of contact for everything from a domestic patio to a port redevelopment.
Working with an authorised distributor also means genuine ULMA drainage channels, correctly matched components and reliable after-sales support — not an approximation assembled from mismatched parts. For specifiers and buyers across the region, that assurance is worth a great deal.
Choosing the Right System
With so much choice, the most economical and reliable specification often emerges from a short conversation about the site, its loads and its hydraulics. Matching range, load class, grating and capacity together avoids both over-specification and costly shortfalls.
Vesmaco OÜ would be glad to help you navigate the options and select the right system for your project. If you are planning anything from a garden path to major infrastructure, contact us for stock, pricing and straightforward technical advice — there is no obligation, just genuine help.
