Environmental Case Study with Balfour Beatty
Traditionally, anchorage solutions for backstays use steel sledges with concrete kentledge blocks loaded on to them. This method requires large quantities of concrete blocks to be delivered to the site yard from Balfour Beatty’s Raynesway, Derby stores, then distributed to site using a Man 4×4 wagon with Hiab to install. The maximum number of blocks that can be carried at any one time is 4, meaning several trips are required per location. Additionally, temporary works are required, and Trackway is also needed to get the Man 4×4 to site.
Together with the Innovations Team, the project team at ZL Great Missenden OHL pioneered the use of the Vulcan Earth Anchor system (distributed by Anchor Systems International) as an alternative to the traditional method of anchorage. These earth anchors are installed by inserting a drive rod into the anchor driving point and knocking them into the ground. The anchors are driven into the ground by using hand tools or excavators. Ground level anchor plates can be manufactured to the required angle for each individual location as needed.
This innovative alternative meant the reduction of materials used, decreased need for temporary works, removed the need for trakway installation, reduced the construction ecological footprint (for size, setup and delivery) and reduced transport costs. Additionally, the steel drive rods can be removed and reused again. Also recycled wooden pallets are used which are returned to supplier for re-use and the plastic shrink wrap used by Anchor Systems is a Biodegradable wrap.
“Having witnessed the use of this system on site, I found the ease of this installation, very impressive. The logistical reduction and numerous beneficial practicalities speak for themselves and I would like to see the implementation of this system on other schemes where possible”
Andy Robinson, Project Supervisor National Grid.
- Reduce relative project ecological footprint through reduction in temporary works and removal of required trakway installation (the need for 915m of trakway was mitigated)
- Reduced need for possible trakway ecological mitigations (i.e. trakway sealing for Great Crested Newts/reptiles)
- Delivering a cost saving of £11,849.74 (trackway and transportation costs)
- Material reuse
- Reduced project carbon footprint for backstays from 260,775kg to 7,727kg, for a total saving 253,048kg CO2*
*Calculated using National Grid’s Carbon Interface Tool (CIT)

Are you still using concrete?
Did you know that concrete is the most destructive material on Earth?
It is the most widely used man-made material in existence. It is second only to water as the most-consumed resource on the planet. In an ever-changing world where we are trying to reduce our carbon footprint, we are overlooking one of the biggest causes. Concrete is said to be responsible for around 8% of the world’s CO2 emissions. We have focused largely over the past several years on reducing our plastic use, yet all the plastic produced over the past 60 years amounts to 8bn tonnes, the cement industry pumps out more than that every two years.
We are not saying never use concrete. There is a place for concrete until we find something else that compares with it without the negative impact on the environment. But why use concrete unnecessarily?
When looking at foundation systems, instead of digging up vast areas of earth and filling them with concrete, look at alternatives.
The Anchor Post and Anchor Screw are made up from 100% recycled British steel, do not require any concrete to hold them in place and there is no digging required or removing of the soil. As there is no concrete there is no drying time and installations can be completed in a single visit. The unique dome head allows for adjustments to be made easily and simply. Bespoke interface plates can be designed to suit each individual application.
On a recent project with Balfour Beatty and Network Rail (see here), our system was used instead of concrete and the below results were recorded:
- 60 per cent time saving on foundation installation
- 40 per cent cost saving of £369 per metre to £221 per metre (derived from man hour savings, elimination of plant requirements, reduced possession requirements)
- 73 per cent embodied carbon reduction on materials, equivalent to 13,920kg CO2e and 89.4 per cent material saving
- Zero on-track plant and zero water consumed
- UK manufacturing and local materials, eliminating mainland European transportation miles

What Is a Vulcan Earth Anchor?
A Vulcan Earth Anchor® is a percussion driven mechanical ground anchor. It can also be referred to as an Earth Anchor or Percussion Anchor.
Vulcan Earth Anchors are used as a cost effective and rapidly installed system to provide a positive force on a verity or projects.
The Vulcan Earth Anchor range was designed by Anchor Systems (International) Ltd as a simple, reliable and cost-effective ground anchoring solution with the ability to provide immediate loading capacities from 1 – 450kN in displaceable ground conditions with extensive applications.
The concept involves a specially designed earth anchor with a larger surface area, attached to high yield tie bars or tendons to suit a variety of conditions, being driven into the ground where it is locked in position. The tensile load is applied, and the exposed end locked off and terminated.
With their ease of use and speed of installation, Vulcan Earth Anchors provide a time and cost saving alternative to more traditional means of anchoring, particularly where tight programme schedules are involved. This combined with the wide range of sizes available means that the Vulcan Earth Anchor has gained recognition across a vast array of applications internationally.
- Larger surface area allowing the Vulcan Earth Anchor to achieve the greatest holding capacity in all ground conditions
- Rapid installation
- Largest range of anchors in the World ranging from 1 – 450kN+
- We are the only company globally to manufacture and stock fully stainless-steel systems
- Bespoke design available
- Huge stock of plant and products with next day delivery available
- Made in Britain

Strong Support for M1 Temporary Works
Read the full article below:
“Anchor Systems (International) was approached by Galliford Try and piling and ground engineering
specialist contractor Van Elle to design a temporary ground anchor scheme forming part of sheet pile temporary works at an under bridge on the M1 junction 13 to 16 smart motorway scheme.
Ground investigation data provided by the client suggested that the anchors would be installed into made ground forming the motorway embankment, a material that can be challenging to work with, due to its varied nature. The required prop forces were defined by the client which allowed Anchor Systems’ in-house design department to select the AS-300 as the correct anchor from its range of Vulcan earth anchors. Once the initial concept was approved by the client, an indemnified design
was provided. This identified the tendon diameter based on load requirements and the acceptable deflections of the sheet pile wall.
To validate the design, which up to this point was based on interpretation of ground investigation data, a series of test anchors was installed and tested to ensure they met or exceeded the predicted performance. Programme constraints meant that vertical test anchors had to be used, installed behind the pile line such that they intersected the stratum where the live anchors would be positioned. Under the supervision of Anchor Systems staff, four test anchors were installed by Van Elle, one at each bridge abutment, using a hydraulic breaker mounted on a 13t excavator. These
were then “load locked” using a high pressure hollow hydraulic ram, achieving a maximum load of 220kN, which Anchor Systems has said is greater than that achievable by other UK ground anchor
manufacturers. The load information, together with details of the installation time, was then used by Anchor Systems’ design department to substantiate the original design. The final design document was then passed to the client for its review and acceptance. Following on from a successful acceptability test and geotechnical design, the systems have been approved and installation is currently underway.”

Record Breaking 450kN Load Achieved With The Vulcan Earth Anchor®
We recently completed a highways project where our Vulcan Earth Anchors® were used to achieve a ground breaking 425kN load.
“Sussex based Anchor Systems (International) Ltd recently designed and supplied a driven ground anchor solution to support sheet piled retaining walls for the Mill Green Outlet Village in Cannock. The overall designers of the scheme, Staffordshire Highways, working with Amey, had specified the load requirements for these retaining structures and provided extensive ground investigation data.
Using this data, Anchor Systems (International) Ltd developed a design ground model with the anchors embedded at a depth of approximately 7m in dense Glacial Deposits. Based upon SPT ‘N’ values of 40, it was predicted that the load requirements could be achieved with their AS-300 and AS-400 Vulcan Earth Anchors.
Extensive site testing was carried out to confirm the anchor performance predicted from the ground model. The initial acceptability testing utilised the AS-400 and managed to achieve a maximum 425kN, making it the highest load ever achieved with a driven ground anchor in the UK. This maximum test load was restricted by the safe structural capacity of the anchor components, not by geotechnical failure of the ground.
The testing programme also provided the opportunity for onsite training in the safe and correct use of the installation and load locking equipment. Amey’s staff were therefore able to install the anchors within their own timescales and avoid the need for outsourced specialist contractors.
The high working loads meant that Anchor Systems (International) Ltd were the only driven anchor supplier capable of meeting the design requirements. Careful choice of anchor materials meant the specified 120 year design life was economically achieved. As Vulcan Earth Anchors require no grout or other wet trades, the anchors were fulfilling their intended purpose immediately after installation.”

Replacing 12 Concrete Kentledge Blocks With a Single Anchor
Our latest site test was for a utility contractor who was looking for an alternative anchoring system for their transmission towers.
They are currently using excessive amounts of concrete to backstay their transmission towers as 8-12 kentledge blocks are needed per anchor point. A single lorry can carry 18-20 blocks so when they need to need to anchor multiple points the cost in transport and storage soon accumulates.
We installed a single AS-120 Vulcan Backstay Anchor which would replace the need for all the kentledge blocks. The anchor is percussion driven into the ground and once used the tendons and accessories can be removed from the anchor and used again at a different site.
The Vulcan Earth Anchors are much easier to transport, over 100 anchors will easily fit into the back of one van. This takes the cost of five lorries off of the budget, saving a huge amount of money and time.
The AS-120 Vulcan Backstay Anchor was successfully installed in front of the utility contractor and relating Distribution Network Operator (DNO). The anchor was driven 3 meters into the ground at a 35 degree angle proof loaded to 60kN which included all the safety factors required for this project.
