Single-slot grating

Aesthetics and hydraulic capacity

The SINGLE-SLOT GRATING is part of an integral system, consisting of a discrete slot, a trench drain body and a sump unit for optimal maintenance of the drainage system. It is an inverted “T” or “L” shaped grating model, that stands out mainly for its aesthetics, since it integrates perfectly in the pavement (either concrete, paving stone or tiles), totally blending in with the urban landscape.

Trench drain with 2.5% slope

Higher hydraulic capacity with sloping channels

These trench drains with built-in slope are the only ones on the market with a real slope of 2.5% which, thanks to their marked slope, provide greater hydraulic capacity, and resolve the slope limitations found in some places like airports.

Hydraulic calculation

We study each project to guarantee the best solution

To ensure drainage systems with optimal evacuation capacity and cost, ULMA Architectural Solutions has developed a multi-platform software solution offering the possibility of performing a hydraulic study for each project and precisely defining the most suitable channel.

Our material, polymer concrete

It is ideal for the evacuation of fluids

The polymeric nature of this material allows smooth surfaces with very low friction on prefabricated elements, thereby facilitating the rapid run-off of fluids and also offering a water absorption index which is virtually non-existent, compared with 5-10% with traditional concrete.
