Since 1995 the first soundproof drainage system in coextruded 3-layer polypropylene (PP) blue color RAL 5014. The widest range available with diameters from 32 to 250 mm is composed of pipes and fittings reinforced with mineral fillers (MV) which give the system excellent acoustic insulation qualities, resistance to impact, corrosion, abrasion and aggression of chemical substances dissolved in civil and industrial waste.

Application scope

Waste drainage system compliant with EN 1451-1 in Class BD (inside the building and outside, as well as underground) suitable for systems in buildings where compliance with regard to acoustic insulation for residential, industrial and commercial, public and receptive such as hospitals, retirement homes and nursing homes, hotels, schools, places of worship. The POLO-KAL NG system is also suitable for the construction of VMC systems (Controlled Mechanical Ventilation), geothermal systems, ventilation, extraction, dust extraction, systems with pressure of the wastewater (booster pumps or Sanitrit type shredders).

Design instructions

The POLO-KAL NG water drainage system can be designed according to the requirements of the design reference standard UNI EN 12056-2. According to these prescriptions, pipes and fittings from the POLO-KAL NG system or, alternatively, BAMVENT ventilation valves can be used for the ventilation of the drainage system. In compliance with DPCM 5/12/1997 on passive acoustic requirements inside buildings (Law in force in Italy), the POLO-KAL NG water drainage system offers high soundproofing performance certified in accordance with EN 14366 at the Fraunhöfer Institute of Stuttgart.

Installation method

Robust and practical system to install thanks to the push-fit joint, secured by an elastomeric gasket. The connection with the socket guarantees adequate space for any expansion of the system with a reliable and guaranteed seal over time. The POLO-KAL NG polypropylene system is compatible for connection with other plastic materials in PP / PE-HD / PVC in standard diameters.

Accessories for installation

A series of accessories useful for the construction of drainage systems are associated with the POLO-KAL NG polypropylene system, including:

  • Valves for drainage ventilation 
  • Non-return valves 
  • Fire protection systems (sleeves – bands – bags) 
  • Single-layer isolating sheaths 
  • Triple-layer soundproofing sheets 
  • Pipe fixing and anchoring collars 
  • Non-slip sealing collars
Special conditions

The special composition of the POLO-KAL NG system ensures absolute sturdiness, especially in severe cold environments, with an impact resistance (laboratory tested) up to a temperature of -20 ° C. Furthermore, in the event of an accident or an accidental hole, the system can be quickly repaired by heat-sealing carried out by an expert hand with special equipment.
