DryLine® Flex channel drain

The DryLine® Flex channel drain, made of stainless steel, is suitable for surface water removal of car parks, courtyards, terraces and inverted structures. Channel drain is dimensioned according to the site-specific needs, taking into account the required load-bearing class and internal slopes. Tailored channel drains allow for the implementation of an easy-to-install solution that can be integrated with other drainage products for even the most demanding applications. All channel drains are equipped with cast-in supports and mounting feet, which make it easy to position the channel at the correct height.

Installation instructions

Maintenance

The channel drain must be maintained regularly. Failure to maintain will reduce or prevent water flow. Particular attention should be paid to cleaning the channel during the gritting season.

  1. Check the condition of the channel and gratings.
  2. Clean clogged gratings.
  3. Open the grating screws and remove the gratings.
  4. Clean the channel and outlets of stones, sand and debris.
  5. Empty the sump unit or sand bucket.*
  6. Check the condition of the thermocable and the protective case.*
  7. Put the gratings in place and tighten the screws.

Frequently asked questions about channel drains

What kind of structure are DryLine® Flex channel drains suitable for?

DryLine® Flex channel drain has to always be installed in concrete casting. For example, in courtyards where the surface material is stone or tile, the bottom and sides of the channel drain must be in concrete casting.

Are DryLine® channel drains suitable for tiled (clinker) surfaces?

Yes, the DryLine® range offers two options for tiled surfaces, either DryLine® Spa or DryLine® Flex:

  • Spa channel drain, is ideal for tiled surfaces. The stylish Spa drain is designed for use with liquid and spray-applied waterproofing membranes. The flange of the Spa drain is connected to the waterproofing, the perforated lower edge of the grating frame allows water to flow into the drain from the surface of the waterproofing layer. Thanks to its slim dimensions, the Spa drain is particularly suitable for low terrace structures.
  • Flex channel drain is suitable for tiled surfaces, e.g. with a slotted grating. The Flex drain is tailored according to the structural thickness of the site.

How do I ensure the load-bearing requirements of the site?

The necessary load-bearing requirements must be verified by the site designer. Depending on the site, it can be a structural engineer, landscape designer or architect. The designer takes into account the load-bearing requirements when determining the location of the channel drains and the load it must withstand, including snow plowing equipment and rescue routes.

Which cover option should I choose for non-trafficked decks?

Our lightest grating option, the slotted grating (A15) made of stainless steel, is suitable for pedestrian walkways. The slotted grating can withstand walking, cycling or other light loads. For example, any snow plowing equipment must be taken into account when choosing a grating that withstands light loads.

Can a channel drain be retrofitted to a existing yard?

Yes, in this case the finished surface has to be opened, for example by spiking, so that the channel drain can be installed and positioned in place with the help of mounting feet. After that, a cast-in-place casting is made to make the drain an integral part of the yard.

I need an 80-meter channel drain, is it feasible?

Yes, we implement longer drains assemblies by connecting approximately 6 m long drains to each other with connecting flanges. With the help of connecting flanges, we can implement assemblies of any length. The material of the connecting flange is either EPDM or NBR rubber, depending on the location and intended use of the drain.

How do I determine the depth of the channel drain?

The minimum depths for channel drains are determined on the basis of manufacturing techniques:

  • Channel drain with slotted grating (stainless steel)
    • With thermocable, height 55mm
    • Without thermocable, height 45mm
  • Channel drain with mesh grating (stainless steel)
    • With thermocable, height 75mm
    • Without thermocable, height 60mm
  • Channel drain with slotted grating (ductile iron)
    • With thermocable, height 65mm
    • Without thermocable, depending on the width of the channel, height 50-55mm

Otherwise, the depth is affected by the structural thickness of the site and, taking this into account, the height of the channel can be freely chosen. A low channel drain requires more frequent cleaning to prevent clogging, a deeper channel has more space.

Can the outlet of the channel drain be placed on the side?

Yes, one or more of the DryLine® channel drain outlets can be freely placed at the bottom, side or end of the channel according to the needs of the site. The diameter of the outlet is determined by the size of the drain, either Ø 50, 75 or 110 mm.

How is the DryLine® channel drain thermocable brought into the channel in a watertight manner?

The thermocable is brought into the channel drain by means of a watertight pressure grommet. The pressure grommet is welded firmly to the drain, at a point specified by the customer. It can be placed at the end, side or bottom, taking into account the electrical plan of the site.

The channel drain is installed in a car park, where petrol may flow into the channel, does the connecting flange withstand chemical stress?

In that case, the material of the connecting flange is NBR rubber, which is resistant to oil and petrol. When ordering a channel drain, it is worth telling our technical sales that the drain will be installed in a car park, so that our salesperson will take care of the right connecting flange for you.
