Overall advantages

Advantages of this innovation
	With the PRIMUSS production method the program controlled manufacture of channels with the required inlet and outlets at different heights and diameters for any pipe connection is automatic, geometrically optimised and dimensionally accurate.
	Mould costs are reduced as a result of early demoulding and short lead times.
	The tool costs and power consumption of the milling robot are low, as the concrete is still part cured.
	No mould parts and formers are required for the channels and connections, just the milling robot with the appropriate software.
	The method is suitable for manholes in nominal widths and diameters 1,000, 1,200 and 1,500 mm
	The residual concrete is recycled.
	Labour costs and costs for the manufacture of the PRIMUS manhole bases are reduced considerably
	The required area for the installation of the plant is small.

Advantages of PRIMUSS manufactured manhole bases
	The manhole bases are produced monolithically from highly-compacted fine-grained concrete.
	Dimensionally exact manhole bases are formed due to partial curing in the mould.
	The Channels are designed for optimum flow.
	PRIMUSS manhole bases are made from concrete with high strength and low water-cement ratio (C 40/50] or from high strength concrete (C 60/75).
	PRIMUS manhole bases are exemplary regarding the environment. No plastic liners or waste materials are used.
