SK 1000 sewage manhole

Monolithic Sewer Manholes – Durable Solution for Sanitary, Stormwater, and Combined Sewer Systems

Product Description:
Monolithic sewer manholes are a solid, safe, and durable solution designed for use in gravity, sanitary, stormwater, semi-combined, or combined sewer networks. They are manufactured using rotational molding (rotomoulding), which ensures a uniform structure, complete watertightness, and high mechanical resistance.

Each manhole series includes 9 height variants of the rising shaft, allowing perfect adaptation to the depth and specifics of the installation. Thanks to their monolithic design, these manholes do not require additional joints along the body, which significantly enhances their durability and resistance to groundwater infiltration.

⚙️ Applications of Monolithic Manholes:

• Gravity sewer networks

• Sanitary and stormwater sewer systems

• Semi-combined and combined systems

• Inspection and cascade manholes

• Water meter chambers or special technological constructions

🧱 Product Features & Advantages:
✅ Rotational molding technology – guarantees a uniform, watertight structure
✅ No vertical joints – high resistance to infiltration and exfiltration of water
✅ 9 shaft height variants – flexible adaptation to installation depth
✅ Suitable for various types of sewer systems
✅ Resistant to aggressive wastewater and soil conditions
✅ Inlet channel connections via in-situ gaskets installed at the base of the manhole
✅ Long service life – over 50 years

Thanks to the use of rotomoulding technology, the entire structure forms a single, watertight monolithic element – without seams, glue joints, or socket connections.
