Linear Drainage

Collects water and effluents all along the channel lines through gratings.

Makes the design of the drainage system and laying-out of areas and maintenance easier compared to spot collecting methods.

Avoids installation of buried pipes

Improves the water-transfer process

linear drainage

Spot collecting drainage

Main features.  Manufactured using Polyacron polymer concrete developed and produced by ALFADRAIN, comprising aggregates bonded by polymer resins.  Available in modules lengths of 1m (and/or 0.5m)

In 3 types (see right)

With internal width of 100, 150, 200, or 300mm.  With standard or mini height.

slopeless channels

channels with 0.6% slope

stepped fall channels

Polymer concrete made from aggregates bonded by polymer resins.

• Ergonomics (minimum weight and overall size.  Precise interlocking of about 1mm and smooth finish)
• Chemical resistance to saline or acid water, de-icing salts, petrol and oils.
• Higher mechanical strengths: resistance to bending and compressive strengths, more than 3 times higher than traditional concrete
• Abrasion resistance
• Waterproof, no absorption of water and effluents, making the product frost free.
• Exceptionally long service life
• Expansion coefficient of the embedded channels equivalent to normal concrete lines
• Recyclable and non-pollutant
• Efficient hydraulic flow due to smooth finish
• Quality level meets the expectations of the most demanding professionals

• A broad selection of gratings, resistance class from A 15 kN to F 900 kN available in  various designs
• A complete range of accessories for connecting and closing lines
