Wembley Innovation is a privately-owned construction products company that sells the Wi System range of patented products, which include:

  • Wi Column
  • Wi Beam
  • Wi Trough Lintel

These bespoke products replace traditional windposts and lintels and offer significant benefits over conventional construction approaches.

We aim to create and deliver the highest quality products, based on rigorous testing and excellent engineering back-up.


Based on the comprehensive R&D work carried out, the Wi System was launched as a viable alternative to windposts. Here are some of the milestones in our history.

May 2010 – Updated Wi System Design Guide

Following the conclusion of the initial phase of Wi Column and Wi Beam testing at Lucideon, the results were tabulated and reviewed by Lucideon, Buro Happold, Jenkins & Potter and Wembley Innovation to enable a comprehensive Wi System Design Guide.

June 2010 – Wi System design for the Olympic Park Aquatic Centre

The Design Team approved the Wi System as a blockwork support alternative for use in the Zaha Hadid  designed Aquatics Centre. Buro Happold and Wembley Innovation developed a Wi System solution for 6m high, curved blockwork panels with no head restraint. The design had to factor-in significant service penetrations and accommodate a temperature differential of 35 degrees.

July 2010 – 8th International Masonry Conference 2010 in Dresden

On 4 July 2010, Professor Geoff Edgell from CERAM presented the final paper on the Wi System to the attendees of the 8th International Masonry Conference held in Dresden. The Wi System testing and developments were closely followed by a number of leading international masonry design experts and the presentation of this final paper highlighted the structural capabilities of the Wi System.

August 2010 – Wi System specified on the Chobham Academy

Architectural firm Allford Hall Monaghan Morris and Structural Engineers, AKT, specified the Wi System for use on the Chobham Academy’s blockwork package. The design consisted of a combination of Wi Columns and Wi Beams. The Wi System design removed the traditional windpost issues of closely centred movement joints and fire protection. The Wi System also eliminated the heavy concrete lintels with the Wi Beams located to provide built-in lintels above door openings.

March 2011 – Olympic Aquatics Centre masonry package completed

Working closely with design consultants, Zaha Hadid and the project engineers, Arup, the Aquatics Centre benefited significantly from a combination of the Wi Column and Wi Beam System to achieve the required lateral wall stability.

The Wi System eliminated 1,100 windposts and 372 lintels whilst also benefiting acoustic and fire protection performance, stabilising part-height walls, maximising flexibility for service penetrations and providing a single substrate for the extensive tiled areas.

July 2011 – 7 metre Wi Column test a success

Further tests of the Wi Column to a height of 7 metres were conducted at the Lucideon laboratory in Stoke on Trent. The structural performance of the Wi Columns was assessed under positive wind loading. Both the columns successfully passed the loading test showing no signs of distress or cracking.

September 2011 – Wi Column / Wi Beam overview and testimonials

A new overview document produced by Wembley Innovation gave an insight into the key features and benefits of the Wi Column/ Wi Beam masonry System, along with explanatory technical diagrams, a review of 3rd party testing, key recent contracts as well as a number of testimonials from contractors and consulting engineers.

October 2011 – Wi Beam shelf angle test success

Wembley Innovation carried out testing to ascertain the suitability and capacity of the Wi Beam System for carrying a masonry shelf angle, loaded with brickwork and a lateral wind load. The results were positive, and will lead to the further development of the Wi System to provide a complete cavity-wall support solution.

December 2011 – RIBA Product Selector

Wembley Innovation was featured for the first time in the RIBA Product Selector publication (RPS Nr 26752). This identified our windpost and concrete lintel replacement products, Wi Column & Wi Beam System. Here’s what RIBA said:
The innovative Wi Column and Wi Beam System is designed to strengthen masonry walls achieving spans of up to 9m without the need for windposts. They are CDM compliant, with a maximum component weight of 14 kg and significantly improve wall aesthetic appearance, airtightness, acoustics and fire performance.

February 2012

37 Patents, Trademarks or copyrights  were approved or pending in the following countries: United Kingdom, European Community, United States, Canada, Australia and New Zealand.  Click here to see details of our latest Patents.

July 2012

The London Olympic’s flagship venue, the Aquatics Centre was revealed to the world. The Wi System was used extensively within the design so that large wall panels could be built without structural concrete and steel columns restricting the placement of M&E equipment.

June 2013

Further testing at CERAM was undertaken to investigate the possibility of achieving enhanced rotational restraint connection between a Wi column and the adjacent masonry panels . The results were successful and thereby allows an increase in the design lengths of restrained panels. Patent applications for this tie were filed.

November 2013

The latest Wembley Innovation Design Guide was published in accordance with Eurocode 6.

September 2014

The Wembley Innovation Design Guide was updated to incorporate the latest Eurocode 6 amendments.  The Wi System Design Program was also launched.

January 2015 – Liverpool Street Crossrail Station

Following a rigorous technical review and approval of the Wi System by Crossrail and Laing O’Rourke, Wembley Innovation was responsible for the full design of the masonry package and supply of the Wi System, including the Wi Slot Block.

August 2015 – Farringdon Crossrail Station

Independent of the Liverpool Street Station success, Wembley Innovation were also successful in being awarded the full design and supply of the Wi System and Wi Slot Block for what was the largest infrastructure project at the time.

June 2016 – Bond Street Crossrail Station

Another Crossrail project where we supplied the Wi System and Wi Slot Block for the blockwork package.

July 2016 – 52 Lime Street, London

Supply of the Wi System and Wi Slot Block on the iconic “Scalpel” building for Bansal Construction.

January 2017 – Stratford East Village

Supply of Wi System for works carried out by Comast.

October 2017 – Battersea Power Station

Commenced full design and supply of Wi System and Wi Slot Block on the original power station building.

December 2017 – Product Testing

Additional full-scale load tests at Lucideon laboratories.
