MANHOLES

ENGINEERED FOR EXCELLENCE

Both PP (Polypropylene) and HDPE (High-Density Polyethylene) manholes are widely used in modern drainage and sewage systems, offering a range of advantages in terms of durability, efficiency, and ease of installation. By structural  form , HDPE and PP manholes can be:

  • Injection molded – Konti Rigid manhole
  • Manufactured, combination of injection molding part and corrugate pipe
  • Special manhole – tailor made, special construction of manholes (non standard). These manholes can be manufactured from KONTI KAN SPIRAL PIPE, inlet and outlet from KONTI KAN pipes.

HDPE MANHOLES

HDPE manholes exhibit high structural strength and rigidity, capable of handling both dynamic and static loads, including traffic loads and deep burial. While stiff, HDPE manholes also have a certain degree of flexibility, allowing them to absorb slight ground movements without cracking.

HDPE is highly resistant to a wide range of chemicals, including acids, bases, and salts, making it suitable for sewage and industrial waste environments.

Characteristics:

  • High-Density Polyethylene (HDPE)
  • Excellent chemical and biological resistance
  • 50+ years service life
  • -40°C to +60°C (short-term higher resistance)
  • Smooth inner surface, reduced friction
  • High stiffness and flexibility for traffic loads
  • Lightweight, quick installation
  • Fully recyclable, environmentally friendly
  • Affordable, low long-term maintenance
  • More cost-effective than concrete alternatives

PP MANHOLES

PP manholes are an excellent choice for modern sewage, stormwater, and drainage systems. They excel in chemical and biological resistance with a material that offers long-term durability, cost-effectiveness, and easy installation, making them suitable for a wide range of applications, including residential, municipal, and industrial infrastructure.

Characteristics:

  • Polypropylene (PP)
  • Excellent chemical and biological resistance
  • 50+ years service life
  • -20°C to +90°C
  • Smooth inner surface, self-cleaning
  • Complies with EN 124 for heavy loads
  • Easy transport, modular design
  • Fully recyclable, energy-efficient
  • Cost-effective, low maintenance

APPLICATION

KONTI PP RIGID MANHOLES are intended for many varied applications and can be used as:

  • Municipal and industrial manholes
