Tecnochannel Flat
TECNOCHANNEL Flat is the latest product from Malagrida Group, specifically developed to address challenges in building renovations where vertical space is limited.
With a minimum thickness of just 3 mm and a standard height of 7 cm, TECNOCHANNEL Flat sets a new benchmark in the field of shallow linear drainage. Combining an attractive design with straightforward installation, this model is the ideal solution where space within the floor structure is minimal.
TECNOCHANNEL Flat is an advanced, 100% watertight linear drainage system that allows efficient surface water runoff. It is suitable for both indoor and outdoor paved surfaces.
The system is made of plastic and consists of 1.50-meter-long modules that connect seamlessly in a continuous line.
The internal cross-section and slope of the TECNOCHANNEL Flat drainage ducts enhance water flow speed and the resulting self-cleaning effect, helping to prevent debris accumulation at the bottom of the channel.
Thanks to its material and structural design, TECNOCHANNEL Flat is extremely lightweight, offering significant logistical advantages.
The system features an internal slope that allows for flat surface installation. Along the perimeter of the channel body is a fin covered with felted fabric, designed to enable the attachment of insulation in thin-bed applications. The frames on both the duct and the special components are made of AISI 316L stainless steel.
The TECNOCHANNEL Flat system is completed with fully compatible special components such as drain terminals, end caps, AISI 304 stainless steel grilles, and accessories to ensure a watertight seal.
Note: Grilles can also be supplied in AISI 316L stainless steel upon request.
The channels are easily accessible for inspection and cleaning.
Areas of application
Assembly
The assembly and installation instructions on the following “Technical Data Sheet” are distributed for demonstration purposes only. Special assemblies or requirements need to be evaluated by Malagrida Group s.r.l. in accordance with the designer. Correct commissioning of the system is necessary in order to ensure that it (duct-grille) has a longer life span and better water flow-off.

See all phases
Phase 1
Check that the lip seals are placed in their housing at the ends of the duct and are not deformed.
Phase 2
Assemble the ducts after lubricating the male joint with the approved lubricant, taking care to place the flat seal between the sections. The flat seal has to adhere perfectly to the mounting flange of the ducts. Position the galvanized iron connecting plates outside the mounting flange of the ducts, and fasten the ducts with the screws and bolts provided, making sure to tighten the bolt using a “criss-cross” sequence, without tightening too much to prevent the flat seal from coming out. Incorrect fastening can compromise the waterproofing of the system. To make assembly easier, we suggest performing the assembly phases mentioned above with the ducts upside down. It is recommended to perform the assembly on flat surfaces. To complete the assembly with elements like the end headers and the drain terminals carefully repeat phases 1-2.
Phase 3
Put the channel into the position of use.
Important Note: If the channel is more than 3 meters long, more installers are required in order to avoid any abnormal twists to the channel. Lay the channel at the project height and make the screed with the grid already mounted.
Note: use only pipes with o-rings seal. Once the previous steps have been carried out correctly, we recommend to flood the channel 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.
Please Note: The step described above must be carried out once the grille has been installed. This is of fundamental importance because it prevents the duct from expanding during freeze-thaw cycles (temperature changes).
Phase 5
Connect the channel with the drainage system (with the proper size and slope).
Please Note: Only use pipes with o-ring waterproof seals.
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 7
Only for Canalina Infinity and Tecnochannel (NO FLAT
Phase 8
To proceed to the FLAT system flooring installation, insert the template in the channel.
Phase 9
Lay the flooring taking care to ensure it adheres correctly to the template (without a joint), proceed in the same way for the full length of the channel, moving the template each time.
Phase 10
Flooring the cover grille. Apply the layer of adhesive, full-bed, on the grid. Place the cover grid in its seating inside the channel, then lay the tile (width 9.6 cm).
Phase 11
To level the floor with the tile laid on the cover grille, use the specific double spacer that can be used to level the tile just by pressing down with your hands.
Phase 12 and 13
The spacer has two different heights: 2 or 3 cm. In case of a floor thickness of less than 2 cm, use the cross with the shorter lower part. In case of flooring with a thickness of more than 2 cm, use the spacer with the longer bottom section. Bevel (chamfer) the tile / marble / stone, in proximity to the run-off joint.

The installation and laying instructions detailed in the following “Technical Data Sheet” are provided exclusively as examples to allow the final fitter to follow the best recommendations for installation. Special assemblies or requirements need to be evaluated by Malagrida Group s.r.l. in accordance with the designer. The correct installation of the system is necessary to ensure it (duct-grille) a longer life and a better water flow.
For the correct use of the example laying diagrams below, we recommend following these simple tips as it will be much easier to find the right item and sizing for your job.
- Identify the linear metres of Technochannel Flat ducting required for your job.
- Identify the position of the drainage points and the diameter of your balconies/terraces/lawns, etc. in order to be able to slope the ducting towards them with the help of the dotted line on the diagrams.
- Choose the Tecnochannel Flat most suitable for your project, taking into consideration points 1 and 2.
- Carefully follow the instructions for use accompanying the products.
- The products have been designed for domestic use, thus limitations of use apply.
- Hot water flowing only for a short time at a maximum temperature of 90°C.
- Do not use chemical cleaners to remove any deposits inside the duct.
- The stainless steel surfaces, exposed to the environmental elements or aggressive substances, should be cleaned periodically using a mild cleaning product. Regular cleaning not only gives the stainless steel a shiny appearance, but also prevents corrosion. The cleaning product must be free of hydrochloric and hydrofluoric acid.
- Avoid contact with other metals, such as for example non-stainless steel, since contact may cause rusting. The same is valid for the use of tools such as spatulas or steel wool, used to clean mortar, glue and filler residues.
- The duct system is suitable for waterproofing with liquid primers or insulation compounds for thin-bed installations.
- To correctly design and choose the appropriate ducting system, it is necessary to know the square meters that the system must drain so that the proper duct size for the application can be determined.
- Periodic maintenance of the duct is recommended to avoid accumulation of dirt inside it.
- The product is sensitive to certain petrol by-products.
