Anchor Bloc: Steady as a Rock

How do you anchor temporary structures like scaffolding, towers, gantries, signage  and shelters in a way that is both utterly steady and safe yet also flexible and mobile?

The answer is Anchor Bloc, a unique product. This system of freestanding modular concrete components is brilliantly engineered to provide steady anchorage and restraint to BS 5975:2008 quality standards while retaining mobility, re-usability and flexibility.

Anchor Bloc is manufactured from an innovative combination of sustainable and recycled materials (patent applied for GB 1113010.1) to offer excellent lifetime costs due to its capability to be reused over many years and in a variety of applications.

Engineered for integration

Anchor Bloc can be used alone, bolted together in modular structures or mechanically integrated into the overall construction to provide ideal anchorage for any temporary structure that also needs to be rock steady and safe.

The high quality smooth polished one tonne (1000 kg) concrete blocks are engineered to be easily moved by crane, fork lift or pallet truck. They can be supplied in yellow/black safety markings, with unobtrusive white PVC decorative covers or in a padded version for use in pedestrian areas.

On site, Anchor Bloc provides a reliable temporary foundation that can be mechanically connected via bolts, scaffold poles, double swivel couplers, ratchet straps or GEWI dywidag connectors.

Use/ Re-Use

The concrete C35 mix comprises of sustainable aggregate sourced through our partner nationwide ready mix supplier, so Anchor Blocs can be constructed on site to reduce transport costs and carbon emissions. Meanwhile the steel work reinforcement contains 98% recycled material. At the completion of a project the blocks can then be relocated to a local storage facility for transport or re-use.

Every project is different but we would be delighted to show you how Anchor Bloc can provide a higher quality and better value foundation for your works.

Better than Ground Anchors & Foundations

  • No risk of coming into contact with underground services
  • Performs well regardless of ground bearing capacity and moisture
  • Nothing left behind to damage farming equipment, etc.

Better than Concrete & Ballast

  • System engineered for consistent mass and quality
  • No protruding reinforcement bars to cause snags or prevent stacking
  • Easy to transport and re-use
  • No poles or sharp edges to endanger pedestrians or cyclists

Better than Water Ballast / IBC

  • No need for nearby water supply
  • No risk of contaminating ground or water courses
  • More rigid and integrated connection to scaffold or structure
  • No vulnerability to tampering or vandalism
  • No vulnerability to freezing, thawing or evaporation

The anchor block temporary restraint system has now virtually replaced all other forms of kentledge within safety ground barriers, height barriers, site signage and pedestrian walkways in place on the CCGT (Combined Cycle Gas Turbine) infrastructure works at West Burton Power Station. The engineered “Anchor Bloc” enables the contractor to provide accurate calculations verifying the suitability of the structure and one block is interchangeable for all solutions.

Previous methods have often been ad hoc and unsuitable for re-use but this has given a professional, effective and efficient solution to all our temporary works which we intend carrying forward on future projects.

We have deployed the C S Scaffold produced precast concrete kentledge block complete with scaffold and screw fix anchorages along with precise weight marked on them extensively on the works we are undertaking at West Burton Power Station. They have been a success both from the economic and practical point of view.

The use as a kentledge for height restrictor structures, for covered walkways or for solid panel perimeter has proved very economic. The designer is able to distribute the kentledge exactly where he needs it, hence reducing the amount. The units are capable of locking together so that where additional kentledge is needed it can be designed in without taking too much room up.

The units are compact and the fixings to the scaffold or fence mean they need the least possible room. Once they are in place they are almost maintenance free, just a quick check on fittings on each scaffold inspection completes the maintenance. A far cry from using packs of blocks or bags of sand as kentledge that needed major maintenance.

Painted yellow and black they give our areas of this major contract a professional look that is pleasing to the Client EDF Energy and this has hidden economic benefits as we appear to have been awarded more work since using these kentledge blocks.

Finally, because the blocks have chamfered corners and stripped paint work they provide the safest form of kentledge we have ever used where pedestrians need to pass.
