 ('SigmaRoc', the 'Group' or the 'Company')

Modular Wall Unit Patent

SigmaRoc (AIM: SRC), the quarried materials group, is pleased to announce it has obtained a UK patent on its Alfabloc Mark II retaining wall systems.

With the acquisition of Poundfield Products Limited ("Poundfield") in 2017, SigmaRoc also acquired a series of patents covering walling systems suitable for the construction, agriculture, sea defence and military applications. Over the years, the Group has continued to develop its product portfolio with further innovations including the evolution of its well-known Alfabloc system.

The Alfabloc is an interconnecting precast concrete walling system produced in the UK, Ireland, Benelux and Scandinavia. Each free-standing section can be interlocked to form a continuous wall of heights up to 6 meters. In this way the Alfabloc system was used at for example Heathrow Airport, nuclear facilities and numerous construction and industrial applications.

The Alfabloc Mark II makes the installation and interlocking even faster and the constructed wall entirely seamless once in place. The Alfabloc Mark II will be produced as an ultra-low carbon product from January 2023. The patent will allow Poundfield to continue its investment in innovative solutions.
