Keystone Concrete Retaining Wall Block System

Keystone uses a unique high strength fixing system which securely locks the component parts in place. At the centre of the system are pultruded fibreglass pins which offer a high shear strength that will last the lifetime of the wall. A combination of Keystone modular units, positive pin connections and soil reinforcing geogrids delivers ‘rock solid’ stability and performance – its enhanced connection between grid and block is critical to ensure economic designs.


Keystone is available on a design and supply basis. Our engineers have a wealth of knowledge and expertise in the field of Geotechnology. Wherever possible we aim to work with clients from the outset, in order to offer them the most cost-effective design solutions possible. This system has a BBA HAPAS Certificate 14/H217. This Certificate holds all of the respective design and construction information.



Keystone’s ability to connect positively with proprietary geogrid systems has enabled it to be built to heights of over 15 metres
worldwide – making it ideal for roadside and bridge locations and its simple, dry build construction enables it to handle the most
challenging site design Keystone’s versatility is ideal for:

  • Retaining Walls
