Piling companies london is an important method of supporting structures when the ground is unstable. In ancient times, the method was most suitable for settlements situated near waterways and rivers. It involves manually forcing timber piles into the ground and fixing them in holes filled with sand or stones. This method was used by the Romans to build bridges and is still used by piling contractors in London today.
Contiguous piling London contractors are highly experienced in the installation of steel sheet pile basements and temporary works. They have experience working in a wide range of sectors, from construction, to rail and road infrastructure and ports. They have expertise in a number of different construction techniques, including pile driven foundations, retaining walls, and bracing.
They offer a variety of piling solutions, including bearing piles. The company is based in Fetcham, Surrey, but services projects across the M25 region. Besides London, Sheppard Piling has completed projects throughout the midlands, Devon, and Dorset. Their fleet of piling equipment is modern and well-maintained to ensure safe and efficient work. They use Soilmec SR75 piling rigs to complete their projects.
Purkelly Brothers was established in 1971 and specialises in piles and reinforced concrete foundations. The company offers contiguous piling for retaining walls and new basements. Contiguous piling is a highly versatile construction technique that involves closely spaced bored piles. This construction technique is used for basements and retaining walls and can be used by building contractors, professional advisors, and homeowners.
Piling is an essential part of building structures. It can support heavy weights and can transform a weak soil into a strong foundation. It also offers a clean and tidy presentation after construction. Piling is a versatile construction technique that can be used almost anywhere. While it is not suitable for all types of soil, it is a great choice for projects that require a strong foundation.
Choosing the right piling contractor can make all the difference in the success of a construction project. Piling contractors in London will assess the ground condition and make sure that their work meets all the structural requirements. This means they can create a firm foundation for the structure and guarantee its structural integrity.
Contiguous piling walls are a structurally sound method for retaining walls. They are ideal for basement excavation and retaining walls where groundwater is not an issue. They are constructed of piles positioned close to one another and tied together by reinforced concrete capping beams.
The UK’s Riverlinx Joint Venture has appointed Sheet Piling UK as its sheet piling partner for the Silvertown Tunnel project. The joint venture comprises Aberdeen Standard Investments, BAM PPP PGGM, Cintra, Macquarie Capital, and SK E&C and has won the contract to oversee the project in 2019. The project is designed to reduce the congestion that occurs daily in the Blackwall Tunnel and improve travel times across the Thames.
As part of this project, the Sheet Piling UK team will install around 350 square metres of steel sheet piles. The sheets will be installed in four bays, and a separate gang will follow behind to install tie-bars and anchor piles. Bay 1 is an extremely critical path for the tunnel boring machine and timely completion is key to avoiding delays in the project. In addition, the construction crews will need to work close to the Emirates Airline Tower and piling across the entrance to the Royal Victoria Docks.
The TM 20 long-reach telescopic leader rig was used to install 30 pairs of 16m-long sheet piles. This method minimized disruption at the project’s south portal by removing the need for temporary enabling works. The sheet piles also provided temporary earthworks support for the project, eliminating the need for additional enabling works.

Open bore piling
When choosing a piling contractor, it’s crucial to make sure that you’re working with someone who’s experienced, qualified, and will be honest about the work. Ask for references, and don’t be afraid to question them. While you’re evaluating their qualifications, it’s also important to know what to expect of the final product.
Open bore piling involves drilling holes into the soil using an auger. These holes can then be filled with concrete. This method is ideal for soils that are cohesive, such as clay. This means that the piles can be used in different soil types, and can be used for a variety of applications.
Open bore piling is also a great choice for subsoils with clay. Piles are drilled to a desired depth using a rotating auger. This method is very quiet, as it causes little vibration. The method is particularly useful for basement retrofitting in London terraced houses.
The idealised soil profile is shown in Fig. 1. These piles were tested in made ground, Woolwich and Reading formations, and a thin layer of River Terrace Gravel. A single test pile was constructed for each soil type and was able to sustain the loads that were placed on it. The resulting piles had a range of adhesion factors, which were within the previously reported range of 0.36 to 0.8.
The test piles were installed in the East London area of Stratford. Detailed reports on the trial include the ground conditions and construction details. The trial has produced a series of results that indicate the effectiveness of the method. The test results, however, do not necessarily support its use for a variety of applications.
The construction of structures in remote areas requires special skills and equipment. In addition to the necessary equipment and expertise, the construction workers must have exceptional skills. Designing a structure on a remote site is tricky, and converting it into reality can be even more difficult. As such, it’s imperative to hire an experienced piling contractor to ensure the best results.
Micro segmental piling is a common method for low headroom and restricted access sites. A rig of three to fifteen tons can drill 250mm to 450mm diameter piles to extreme depths of 15m. A fifteen-ton rig can drill 300mm to 600mm diameter piles to depths of 17m. A concrete beam is usually formed along the top of the piles, known as a capping beam. This adds structural integrity to the piles. Typically, piling is required at three-metre intervals and at most junctions.
Grundomat piling is an advanced method of laying a foundation. This innovative method involves prefabricated, ERW steel tubes that are driven into the ground. They then contain a dry concrete mix and are electrically welded to each other. The set resistance of the piling is measured in millimetres per second. This method is ideal for a wide variety of applications, including domestic and commercial construction.
I once hired a London piling contractor to install a piling system on a building project. I needed to determine how much SWL would be needed for a project of that size. The engineer recommended 220mm diameter driven piles with 320kN SWL. However, the engineer used a formula from my old boss, which predicted the piles to be less than half that value. The contractor assured me that his piles would be fine, but they struggled to reach the required design set. The hammer was not light enough for the job. When a load test was carried out, the piles failed to reach the desired SWL. Eventually, the project had to be re-piled.
Mini piling is an ideal solution for construction projects where there is limited access or when deep foundations are not practical. This solution can be used for new-build housing, underpinning an existing structure, mezzanine floors, and retaining walls. Mini piling is an environmentally friendly method for building foundations and can be integrated into your existing foundation system.
