Herrenknecht International Ltd

Innovative tunnelling technology from Herrenknecht has helped to build new, efficient supply and disposal infrastructures in more than 80 countries worldwide. On the basis of our entire range of methods, we work closely with our customers and develop tailormade technical solutions. Together, we overcome all challenges and create robust, sustainable tunnel structures – within budget and on time, maximizing safety for people and cities.

Project requirements and the geological and hydrological conditions determine the optimum machine type. Our product range includes:

Earth Pressure Balance (EPB) Shield: Ideal for soft and cohesive soils.
Mixshield: Very large excavation diameters can be controlled safely – also in heterogeneous geologies.
Single Shield TBM: Ideal for tunnelling through rock and other stable, non-groundwater-bearing soils.
Double Shield TBM: Perfectly suited for long tunnelling through hard rock.
Gripper TBM: Proven, efficient solution in hard rock.
Partial-face Excavation Machine: Directly controllable, easily convertible and adaptable in different geologies.
AVN, AVNT, AVND: The best option for microtunnelling: AVN Machines from Herrenknecht.
Auger Boring Machines: The ideal technology for short underground drives:
HDD Rig: Flexible and environmentally-friendly: for tunnelling in stable, loose soils and rock.
Direct Pipe®: This method combines the advantages of microtunnelling and HDD technology. In one step only, a prefabricated pipeline can be installed and the required borehole excavated at the same time. This allows speedy and highly economic installation of pipelines with lengths of more than 1,500 meters.
Vertical Shaft Sinking Machine VSM: Unique method for lowering shafts of all kinds in soft and stable soils.

Faringdon to Blunsdon Trunk Main Phase 2 (2023)

The water network in the western end of the Thames Valley Supply Area is dominated by local borehole water sources. Over time, population growth coupled with general environmental drivers to reduce reliance on groundwater sources in sensitive chalk stream areas, Thames Water has sought to improve supply resilience and deployable output by linking local sources […]

High Frequency Risk Reduction: Garstang Road (2021)

In the PR19 agreement, water companies were encouraged to provide resolution to long-standing flooding problems being experienced by customers – but allowed a less prescriptive approach on the actual projects defined in the Water Company’s (WCo’s) Price Review submission. This new process allowed WCo’s a degree of discretion on the number and frequency of flooding […]

Tideway East - TBM Delivery (2021)

The Thames Tideway Tunnel is a new storage and conveyance tunnel running through the centre of London, mostly under the River Thames. The main tunnel, which is approximately 25km long with an internal diameter of 7.2m, will run from Acton in the west through to Abbey Mills in the east. The project has been split […]

Withernsea Long Sea Outfall - Part 2 (2021)

August 2020 saw the successful completion of a new 3.5km outfall pipeline comprising of onshore (2.5km) and offshore (1km) sections on the Holderness Coast in Withernsea, East Riding of Yorkshire. Due to continued coastal erosion, the purpose of the project was to relocate the existing Withernsea WwTW further inland and replace the exposed existing long […]

Withernsea Long Sea Outfall - Part 1 (2020)

Withernsea is located in Yorkshire, approximately 18 miles east of Hull on the Holderness Coast. The area is vulnerable to coastal erosion due to the geology being mainly soft boulder clay. Groynes and sea walls being installed in Bridlington and Hornsea have affected the longshore drift, which has caused Withernsea area beaches to narrow, providing […]

BRP - Elan Valley Aqueduct - Birmingham Resilience Project (2020)

Between 1893 and 1904 the Birmingham Corporation dammed the Elan Valley in Wales and constructed an aqueduct to channel water to Birmingham. At the height of the industrial revolution, between 1800 and 1900 Birmingham was booming, and its population rose substantially. Following outbreaks of smallpox and diarrhea, city officials deemed it essential to provide its […]

BRP - Raw Water Project - Birmingham Resilience Project (2020)

The Birmingham Resilience Project (BRP) is designed to provide a backup source of raw water from the River Severn to the water treatment works that serves Birmingham. During planned or unplanned outages of the primary water source, the raw water system will abstract water from the River Severn between October and March and supply 117 […]

Anchorsholme Outfall Pumping Station (2019)

Anchorsholme Park is located on the coast 4 miles north of Blackpool Tower. The outfall pumping station project is the second of three phases contributing to improving bathing waters on the Fylde coast. The objective of the overall scheme is to complete the AMP5 obligations on the Fylde Coast of the ‘moving towards three spills […]

Paisley Tunnel Project (2019)

Scottish Water’s £17m Paisley Environmental Project, which started in October 2016, is the largest of its kind that Scottish Water has ever made in Renfrewshire. The project is part of the company’s £250m, six-year programme of work, launched in 2013, to improve river water quality and the natural environment and tackle flooding across the Greater […]

BRP - Elan Valley Aqueduct (Nantmel and Frydd Wood) - Birmingham Resilience Project (2018)

At the height of the industrial revolution, Birmingham’s population was booming. Between 1800 and 1900, the city had grown substantially. An innovative solution was needed to provide its residents and industries with safe drinking water. James Mansergh had identified the Elan Valley as a source for water. With Birmingham located so far in land, the […]

Blackpool South Surface Water Strategy (2018)

The Blackpool South Surface Water Strategy is a £30m scheme aimed at improving bathing water quality along Blackpool’s golden mile. The project tackles the combined challenges of climate change, an aging Victorian sewer network, increasing urbanisation and a responsive catchment. The project’s objectives are the reduction in frequency and quality improvement of spills within the […]

BRP - Elan Valley Aqueduct (Bleddfa) - Birmingham Resilience Project (2017)

Anchorsholme Park Storage (2016)

Anchorsholme Park is located on the coast 4 miles north of Blackpool Tower. The storage project is the first of two phases contributing to improving bathing waters on the Fylde coast. The objective of the initial phase is to complete the AMP5 obligations on the Fylde Coast of the “moving towards three spills per bathing […]

Burham Strategic Water Main (2016)

By delivering its largest and most challenging pipeline scheme to date, South East Water has secured the water supply to thousands of homes and businesses in north Kent and provided the area with critical new infrastructure needed to promote development and growth for decades to come. All while enhancing the environment and reducing operational costs. […]

Shieldhall Tunnel (2016)

Construction of the Shieldhall Tunnel, the biggest investment in the Glasgow wastewater network since Victorian times, is well underway. Once complete, it will improve river water quality and the natural environment of the River Clyde and its tributaries, enable the Greater Glasgow area to grow and develop, alleviate sewer flooding key locations and deal with […]
