UltraRib systems are designed for use in gravity drainage and sewerage installations at depths of up to 10 metres. UltraRib is a fully socketed system of pipe and fittings which combines secure jointing with ease of installation.

Corrugated pipe is a flexible material, built with alternating ridges and grooves. It is used in drains where flexibility, durability and strength are important. UltraRib pipe has a smooth inner surface and externally has a repeating pattern of concentric ribs which gives the pipe its exceptional axial rigidity and enhanced radial strength. 

UltraRib has been designed and manufactured to exceed all required industry standards for PVC-U systems, OSMA UltraRib has provided foul and surface water solutions that have been relied upon for over 30 years.
