Per Aarsleff A/S is a Danish civil engineering and construction company. It is one of Europe's main civil engineering companies.
It was founded in 1947 by Per Aarsleff.
The company is based in Aabyhøj in the western parts of Aarhus, Denmark. It has around 6,500 staff worldwide.
The Aarsleff Group is the largest producer of concrete piles in Europe. The Danish subsidiary producer of precast concrete piles Centrum Pæle was founded in 1966, and is based in the city of Vejle.
Per Aarsleff (UK) Ltd, known as Aarsleff Ground Engineering (previously Aarsleff Piling), is based in New Balderton in Newark-on-Trent. The UK site also contains Centrum Pile Ltd, and mainly makes concrete piles. The UK subsidiary was founded in 1991 and is the leading supplier of precast concrete piles in the UK.
The company has been asked to provide the concrete deep foundations for civil engineering projects, such as for bridges or wind farms. For windfarms, it has worked with Bilfinger Construction GmbH of Germany (now owned since 2014 by Implenia of Switzerland). Denmark is home to some important wind turbine manufacturing companies.

Geotechnical engineering, also known as geotechnics, is the branch of civil engineering concerned with the engineering behavior of earth materials. It uses the principles of soil mechanics and rock mechanics for the solution of its respective engineering problems. It also relies on knowledge of geology, hydrology, geophysics, and other related sciences.
Retaining walls are relatively rigid walls used for supporting soil laterally so that it can be retained at different levels on the two sides. Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to. They are used to bound soils between two different elevations often in areas of terrain possessing undesirable slopes or in areas where the landscape needs to be shaped severely and engineered for more specific purposes like hillside farming or roadway overpasses. A retaining wall that retains soil on the backside and water on the frontside is called a seawall or a bulkhead.
In engineering, a foundation is the element of a structure which connects it to the ground, and transfers loads from the structure to the ground. Foundations are generally considered either shallow or deep. Foundation engineering is the application of soil mechanics and rock mechanics in the design of foundation elements of structures.
Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" (compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service.
In construction or renovation, underpinning is the process of strengthening the foundation of an existing building or other structure. Underpinning may be necessary for a variety of reasons:
The Narrows Bridge is a freeway and railway crossing of the Swan River in Perth, Western Australia.
The Masnedsund Bridge is a bascule bridge that crosses Masnedsund between the islands Masnedø and Zealand in Denmark. It carries road and railway traffic, as well as pedestrians and bicycles.
The Bandra–Worli Sea Link is a bridge that links Bandra in the Western Suburbs of Mumbai with Worli in South Mumbai. It is a cable-stayed bridge with pre-stressed concrete-steel viaducts on either side. It is a part of the proposed Western Freeway that will link the Western Suburbs to Nariman Point in Mumbai's main business district.
A pile driver is a device used to drive piles into soil to provide foundation support for buildings or other structures. The term is also used in reference to members of the construction crew that work with pile-driving rigs. One type of pile driver uses a weight placed between guides so that it can slide vertically. It is placed above a pile. The weight is raised, which may involve the use of hydraulics, steam, diesel, or manual labour. When the weight reaches its highest point it is released, and hits the pile, driving it into the ground.
A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site.
The Cube is a 25-storey mixed-use development in the centre of Birmingham, England. Designed by Ken Shuttleworth of Make Architects, it contains 135 flats, 111,500 square feet (10,359 m2) of offices, shops, a hotel and a 'skyline' restaurant. It is the final phase of The Mailbox development.
Elematic Oyj is a Finnish company founded in 1959. It supplies production technology, machinery, equipment, software and knowhow for precast concrete industry worldwide. It is a precast concrete machinery manufacturer. 90% of its products were exported in 2019.
The Leiths Group is a group of construction-related companies based in Cove, Aberdeen, Scotland. The group includes the following companies:
GRAITEC is an Autodesk Reseller and developer of CAD / CAE software for the civil engineering and construction industries.
The Infinity Bridge is a public pedestrian and cycle footbridge across the River Tees in the borough of Stockton-on-Tees in the north-east of England. The bridge is situated one kilometre downriver of Stockton town centre, between the Princess of Wales Bridge and the Tees Barrage. It connects the Teesdale Business Park and the University of Durham's Queen's Campus in Thornaby-on-Tees on the south bank of the Tees with the Tees Valley Regeneration's £320 million North Shore development on the north bank.
Gammon India Limited is one of the largest civil engineering construction companies in India. Headquartered in Mumbai, it was founded in 1922 by John C. Gammon.
The Surtees Bridge is a road bridge carrying the A66(T) road east west across the River Tees near Thornaby-on-Tees in the borough of Stockton-on-Tees in the north east of England. The bridge is situated one kilometre upriver from Stockton town centre, just upriver of Surtees Rail Bridge – a rail bridge carrying the Tees Valley Line. Built at a cost of £14.3 million the bridge replaces an earlier Surtees Bridge (1981) that showed signs of distress resulting from excessive settlement.
The Franki piling system is a method used to drive expanded base cast-in-situ concrete (Franki) piles. It was developed by Belgian Engineer Edgard Frankignoul in 1909.
Nass Corporation B.S.C. is a Bahraini public joint-stock company established and listed on the Bahrain Stock Exchange since the year 2005. The paid-up capital is currently BHD 22 million.
Buckland & Taylor Ltd was a Canadian structural engineering firm specializing in bridge design and also research and building code development. It was founded in 1972 by Peter G. Buckland and Peter R. Taylor. Both had had experience with the design of major bridges. The firm continued until it was merged into COWI North America, a subsidiary of COWI A/S of Denmark, in 2015.
