2. Technological capabilities

Multifunctional gully system AS can be: inspection, drain or sump and consist of:

• Full adaptor ring or 3/4 (inlet)
• Strenghtening ring
• Transitional/passage elements type 'A'
• Elements with a 'B' typed bottom
• Dirt bucket

3. Technical information

Dimensions:

• length: 675 mm

• internal width: 303mm
• height:  transient element 440mm, element with bottom 450mm

THE CHANNEL BODY 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 BODY WALLS are protected with a coloured impregnation which limits water vaporization at the concrete curing time and protects the channel against environmental aggressiveness. The impregnation increases also adhesiveness of the external wall to the concrete housing. Applying the coloured impregnation makes it easier to control if protection has been made correctly. The channel bodies are finished with “male” and “female” cut outs enabling to provide tight connection of AS drainage system elements.

Inlet- an adaptor ring adjusted to the street inlets AS-WU 400x600 as well as to street inlets produced by other companies.

The wells incorporation- it is carried out on a foundation base

Combining elements- 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.

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.

The wells for AS street inlets will allow you to avoid burdensome breakdowns/damages and degradation of the construction on condition that the installation instructions and design guidelines will be applied correctly.Therefore,the maintenance will be limited to cleaning only.
