Krah pipe technology allows for monolithic, leak-free sewer systems complete with manholes and connections.
	Possible for long and short pipe relining: can be pushed or pulled.

	Can be electro-fused in narrow and short trenches
	High inherent stability
	Possible in large diameters
	The pipe wall can be customized to withstand specific earth loads.
	Manholes are fabricated with Krah extrusion-welding units from Krah pipe stock.
	The entire sewer systems are permanently tight
	High ring stiffness compared to the weight of the pipe
	Quick and easy installation
	No axial displacements due to profile anchorage in soil
	Abrasion resistant
	Inspection friendly due to bright coloured co-extruded pipe wall
	Especially significant for sewer applications, HDPE is inert to hydrogen sulfide, a gas commonly found in sewers. HDPE is also resistant to hot soil conditions (pH between 1.0 and 5.0).
	Resistant to earth movement and plant roots
	Easy house connections: Tapping does not affect wall stability. Easy to install and connect to PVC and other materials.
	Connections to concrete manholes and other systems (special connectors with integrated electro-fusion)
	In addition to electro-fusion, other jointing methods are possible: flanged, gasketed, and extrusion-welded joints.
