One Line
TECNOCHANNEL One Line is the latest product from Malagrida Group, specifically created to address renovation challenges in areas with limited height.
Designed with an extremely low profile (70 mm at screed level and 85 mm at finished floor level), the Tecnochannel One Line system stands as a benchmark in the field of shallow linear drainage.
Featuring a sleek, innovative design and all the technical solutions required for a simple, easy-to-install product, Tecnochannel One Line is the ideal drainage solution where there is insufficient space within the floor structure.
TECNOCHANNEL One Line is an advanced, 100% watertight linear drainage system that ensures efficient surface water runoff.
It is suitable for paved structures in both indoor and outdoor environments. The system is made of plastic and consists of 1.50-meter-long modules that are continuously connected.
The internal cross-section and slope of the TECNOCHANNEL One Line drainage channels enhance water flow speed and the resulting self-cleaning action, preventing debris from accumulating at the bottom of the channel.
Its material and construction design make TECNOCHANNEL One Line extremely lightweight, providing all the logistical benefits that come with it.
TECNOCHANNEL One Line features an internal slope, allowing elements to be installed on a flat surface, thereby simplifying and improving the installation process.
Around the body of the channel is a flange with a layer of felted fabric, allowing for secure attachment of insulation in thin-bed installation systems. The frames on both the channel and the special components are made of AISI 316L stainless steel.
The TECNOCHANNEL One Line system is completed with compatible special components, such as drain terminals, end caps, and accessories to ensure perfect water tightness.
Note: Grilles are available in AISI 316L stainless steel upon request.
The channel can be easily inspected and cleaned via the central drain openings.
Areas of application
Discover all stages
Phase 1
Check that the lip seals are placed in their housing at the ends of the duct and are not deformed. When assembling, respect the order of the letters printed on the duct body (A-A/B-B/C-C).
Phase 2
Assemble the channels after having lubricated the male joint with the approved lubricant, ensuring to put the flat seal between the channels. The flat seal has to adhere perfectly with the mounting flange of the channels. Position the galvanized iron connecting plates outside the mounting flange of the channels, and fasten the channels with the screws and bolts provided, making sure of tightening the bolt using a “criss-cross” sequence, without tightening too much to avoid spilling the flat seal. This incorrect fastening can compromise the waterproofing of the system. To make the assembly easier, we suggest to undertake the above mentioned phases of assembly with the channels upside down. It is recommended to perform the assembly on flat surfaces. To complete the assembly with elements like the end caps and the drain terminals carefully repeat Phases 1-2.
Phase 3
Put the ducting into the position of use. Please Note: If the channel is more than 3 meters long, more fitters will be required in order to avoid any abnormal twists to the duct. Lay it at the desired height. Please Note: Once the previous steps have been carried out correctly, we recommend flooding the duct system to check its waterproofing.
Phase 4
Make the formwork or duct access box (as shown in the figure) with structural fluid cement mortar with a minimum thickness on the side of the felted fins of 5 cm, taking care to fill it evenly on the exterior.
Phase 5
Connect the channel with the drainage system (with the proper size and slope).
Note: use only pipes with o-rings seal. Use only pipes with o-rings waterproof seal.
Phase 6
Run the sloping screed up against the previously made concrete formwork or box, taking care not to ruin the fabric on it, as this would result in a reduced seal of any waterproofing system to be carried out later. We recommend protecting the fabric. Any waterproofing must be carried out in adherence to the felt flap in accordance with the instructions provided by the manufacturer of the waterproofing system. It is necessary, however, in order to connect the waterproofing system and the channel, to apply the strip junction (ARTICLE INF/BAND) listed in the catalogue/price list.
Phase 14 (One Line without profiles)
This stage – crucial at this point in the flooring installation – relates to the drainage elements of the system: INF/S90/OL8 or INF/S90/OL12 or INF/S90/OL16 and TCN/SD50/OL8 or TCN/SD50/OL12 or TCN/SD50/OL16. The first thing to be done when paving is to glue (with an outdoor cement glue) a floor strip with the measurements shown in the figure in adherence to the previously inserted template into the slots of the aforementioned drains.
Phase 14A (One Line with H15 profiles)
This stage – crucial at this point in the flooring installation – relates to the drainage elements of the system: INF/S90/OL8P15 or INF/S90/OL12P15 or INF/S90/OL16P15 and TCN/SD50/OL8P15 or TCN/SD50/OL12P15 or TCN/SD50/OL16P15. The first thing to do when flooring is to glue (with an outdoor cement glue) a floor strip with the measurements shown in the picture, leaving the silicone expansion joint as shown in the drawing.
Phase 15 (One Line without profiles)
Insert the templates one after the other, inserting them into the steel crosspieces through the slots. Lay the floor in adherence to the templates.
Phase 15A (One Line with profiles)
Lay the floor, leaving a silicone expansion joint as shown in the drawing.

Faqs
What are the advantages of a single-slot drainage system compared to traditional systems?
The main advantage is undoubtedly aesthetic: the single slot is discreet and blends seamlessly with tile joints.
Although the Tecnochannel One Line grating is only a few millimeters wide, our systems guarantee excellent drainage capacity.
In which environments is it recommended to use a single-slot drainage system?
We recommend it in all settings where architects, landscape designers, and interior decorators place particular importance on appearance.
Malagrida Group’s One Line drainage channels are specifically designed for wellness centers, gyms, shopping centers, and for the outdoor areas of villas and buildings.
How is maintenance performed on a single-slot drainage system?
Malagrida Group’s single-slot channels include an access point near the drain, from which the internal duct can be inspected and cleaned.
To remove sludge and debris, simply use a high-pressure water jet, guiding it through the entire length of the duct.
How much does it cost to install a linear drainage channel?
Costs vary depending on the size of the system and the complexity of the project.
Malagrida Group channels are made of PP (polypropylene)—a lightweight and durable thermoplastic polymer.
The patented connection system requires no silicone, and the internal slope allows installation on flat surfaces.
Thanks to these features and their reduced thickness, our systems have lower installation costs compared to competing solutions.
