Wastewater solutions: heavy-duty systems for modern infrastructure

Requirements for modern wastewater networks vary significantly depending on soil conditions and installation method. OHM consistently relies on PE 100‑RC (Resistance to Crack): maximum chemical resistance combined with high safety against slow crack growth (SCG) and point loads. Unlike conventional materials such as concrete or vitrified clay, PE is fully corrosion‑resistant against aggressive wastewater.

For demanding projects — including trenchless and sand‑bedding‑free installation — OHMtec RC (PE 100‑RC) provides maximum safety and a robust design for everyday construction site use.

Cost efficiency & installation methods

PE 100‑RC is a key lever to optimize your construction logistics because it reliably supports demanding installation methods:

• Sand‑bedding‑free installation: use of suitable on‑site excavated material (depending on soil class), reducing disposal costs and replacement material.
• Trenchless methods: high safety in horizontal directional drilling (HDD), pipe bursting or ploughing thanks to outstanding notch toughness.
• Jointing technology: fully restrained welded joints via butt fusion (HS) or electrofusion (HM).
