    Slot monolith drainage channel - 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 inner part of a channel is covered with PVC layer which has many advantages:

    -    chemical resistance 
    -    smooth inner surface
    -    tight connection by means of a rubber gasket

    Setting the channels  - on a concrete strip footing.

  • 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.

  • 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. Due to a solid grate fastening, the AS drainage systems are absolutely safe when utilizing the pavement.

    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 using multifunctional basin AS-ST250 once a year.
