Installation instructions for drainage channels
General works site layout conditions
The ULMA Architectural Solutions drainage system has been designed and tested under the strictest premises of EN1433 STANDARD, following the construction details set out in these installation instructions.
The design of the deck adjoining the concrete block/channel unit (concrete, asphalt or paving stone) must be endowed with the expansion and retraction joints required to prevent any tangential or perpendicular strain on the concrete block and channel unit. In line with the construction details of the deck, the sizing of said joints will be decided by the Project Management or designer.
The illustrations below show what the appropriate installed section should be for each flooring type and type of load as well as the recommended construction details.
- Asphalt Paving
- Concrete Paving
Indications common to the different Installation types
The cable conduit or ditch must be deep and wide enough to meet the block dimensions recommended in table 1 in line with the type of load required.
Take special care with the installation of an edgeless channel; the grating thickness must be such that, once the installation has been completed, it remains below the flooring as recommended in Detail A.
In the event that a compacting process is required in the vicinity of the channel (e.g. asphalt flooring load class A15 and B125), special care must be taken not to damage the channel edge and walls.
The surrounding flooring and concrete block must remain on a plane of between 3 and 5 mm above the plane of the upper edge of the channel.

The installation of the channels will start at the removal point or the deepest point.
Should any of the coats adjoining the concrete block in turn, be made of concrete, an expansion joint must always be placed between the block and said concrete coat.
Before pouring the concrete corresponding to the concrete block, place wooden slats or even the gratings themselves protected by a plastic cover so as to avoid deformations which prevent the subsequent installation of the gratings.
When opening the premarked outlets (vertical or horizontal), it is recommended to tap the perimeter every 5-6 cm with a drill or a rotaflex so as to subsequently be able to open the premark carefully with a hammer and chisel.
The channel must not be used as an expansion joint. This is why whenever there is concrete alongside the concrete bedding, an expansion joint must be placed between both coats. The adjoining deck must be endowed with those expansion and retraction joints required to avoid lateral thrusts onto the concrete bedding.
It is recommended to carry out the retraction joint perpendicular to the channel every 6-7 metres and to make it coincide with the union between the channels.

Advantages of linear drainage for channels
Here at ULMA we give a little bit more than channels and gratings. We provide solutions through a complete drainage system which includes:
- 1ML modular channels.
- 1/2 ML linear and siphonic sump units
- Channel Gratings:
- Made of various materials: ductile iron, galvanised steel, stainless steel, composite, polymer concrete,...
- With different designs: slotted, mesh, perforated, single-slot, closed,...
- Endowed with type of load up to F900 in accordance with Standard EN 1433.
- Various accessories such as start and end covers, locking bars, screws etc.
ULMA channels represent a new way of thinking about surface drainage. Occasional drainage or by means of gullies has been surpassed in Europe and the US by linear drainage.
- Facilitates the implementation of slabs or floorings.
- It is hydraulically much more efficient than occasional drainage.
- Prevents waterlogging in occasional areas.
- The grating is such that it is registrable at any point, facilitating cleaning and system maintenance.
- Absorbs minimum slopes of the site without any need for complicated implementations at the works site.
- It is much more feasible in terms of the final cost of the drainage system.
Compressive strength Polymer concrete applied to prefabricated systems can withstand over 1000 kp/cm2 of compressive strength, compared with the 257 kp/cm2 which traditional concrete can bear before breaking or cracking.
Ideal for fluid run-off 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 virtually non-existent, compared with 5-10% with traditional concrete.
Resistance to chemicals Polyester resin, which polymer concrete is made of, is a material which can withstand a very broad range of chemicals as it is inert and does not react when in contract with said chemical compounds in different concentrations.
Remains unchanged in freezing and thawing cycles Contrary to traditional materials, this one is not affected by freezing and thawing cycles, avoiding the appearance of fissures or cracks and keeping all its physical properties intact.
Lightness Thanks to its excellent mechanical properties, it allows parts with a finer profile to be made. Lightness which becomes savings by reducing the use of auxiliary means of transport to the works site and facilitating their installation at the site with unbeatable performance.
Abrasion wear and tear The hardness of the silica aggregates ensures the good upkeep of those surfaces exposed to wheeled traffic owing to the polymer concrete's optimum resistance to abrasion.
Shock resistance The properties of this material, along with its optimum prefabrication design, increase its capacity to withstand and absorb crash forces, affording great resistance to impacts.
Hydraulic calculation Optimal Drain
ULMA Architectural Solutions Hydraulic Calculation software
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.
- Simplicity It only requires a few project parameters, such as line lengths, catchment areas, slopes and run-off coefficients of each surface, to accurately reflect the current situation and the subsequent study.
- Precision To calculate the water&'s behaviour in the channels a mathematical model is used that takes the Spatially Varied Flow with Increasing Flow for Open Channels as the base, which describes the water's behaviour more accurately than other commonly used models and formulas.
- Multiple Functionalities You can enter different rainfall data for any geographic area worldwide, calculate different channel lines in the same project and find the right channel among hundreds of references in ULMA's extensive catalogue, based on their Heights, Widths, Sections, Load Classes or other characteristics.
- Cost Reduction The software optimises the cost of channel lines by selecting the most appropriate channel for the application, the exact location of intermediate outlets or the exact distribution of channels in cascade slope.
- Detailed Report As a result we obtain a report with references and dimensions of the necessary channels, sheet of water, filling percentages, water flows and speeds in each of the project lines. All the necessary data for the validation of the drainage system.
