  • 1. Intended use – place of application

    Applies in areas such as : warehouses,roads,streets,carparks,entries,petrol stations,maneuvering areas, car washes, and areas exposed to very strong loads like airports,docks,military bases etc.

  • 2. Technological capabilities
    • possibility to connect parts at some angle and to make cascade connections
    • basins with thrash boxes, covers with a stub pipe, blanking-off covers,
    • bodies with holes in the bottom or in the side walls – to drain water
    • marking and numbering facilitates to assemble the parts into appropriate systems 
  • 3. Technical information


    • length: 1000 mm
    • external width: 603 mm
    • internal width: 303 mm
    • height: 660, 540 mm


     Monolithic channel body - 'type I' are made of reinforced concrete and do not require lateral bracing - just a foundation base.

    Is made of concrete in the C55/67 strength class with polymer additives and reinforced with alcali – resistant glass fibre.

    This concrete improves the properties of the channel and makes it more resistant to bending and hitting. This concrete is also resistant as well as to long – lasting exposure to frost and defrosting salts (“+R").

    The channel bodies are finished with “male” and “female” cut outs enabling to provide tight connection of AS drainage system elements.

    SUPPORTING SLATS are made of hot-dip galvanized rolled steel and are fixed to the body walls. These slats protect the channel edges and constitute solid element to fasten the grates.

    GRATES – made of cast iron – coated with KTL -  in the classes from C250 kN, D400 kN, E600 kN to F900 kN.

    GRATE FIXING – with stainless bolts, screwed into galvanized , threaded seats made in the supporting slats. The fixing seats are through – adapted for cleaning.

    SETTING THE CHANNELS – on a concrete strip footing with a lateral concrete encasement.

    CONNECTING CHANNELS – applying frost and water resistant mortars.

  • 4. Quality, workmanship precision, and others

    This very simple and safe to install and apply product, entirely fabricated of Polish materials by a domestic company is of very high quality.

    The top product quality is assured by AS PPH A. Sobiesiak due to applying "High Strength Concrete" and materials protected permanently against corrosion.

    The guarantee of the top quality is the ISO 9001:2008 certificate, too.

  • 5. Safety

    Applying AS drainage system does not cause any safety risk when installing it, however the general regulations of occupational safety and health for Construction and Installation works should be followed.

    Drainage of the pavement with the AS system and with simultaneous observance of the designing guidelines and installation instructions will enable to avoid troublesome breakdowns and a building degrading, and the maintenance will be limited to cleaning the channels once a year.
