SCP Environmental design and supply retaining wall solutions for all construction developments. Our new Allan Block segmental retaining wall system, originally designed in Minneapolis, USA, is now available in many countries all over the world. Allan Block, new to the UK, is being manufactured by Colinwell in Belfast, Northern Ireland. Colinwell have been manufacturing architectural masonry since 1888 so have a wealth of experience in the manufacture and supply of concrete block walling. Our partnership with Colinwell will see the Allan Block systems become a natural choice for retaining walls throughout
the UK and Ireland. There are three main systems available, both the AB Classic and AB Stone blocks can be used to create retaining walls up to and over 10metres high when used with geogrid reinforcement. The AB Courtyard range is for small garden walling, ideal to match the low dividing walls in with the retaining structures found on most sites now across the country.

AB Stones
The hollow core makes AB Stones easy to handle, promotes drainage and becomes rock solid when filled. The patented interlocking front lip creates a built in setback and eliminates the need for pins, clips or mortar. AB Stones 12º from vertical batter give efficient structural performace.
Our signature block, the AB Stone is your best choice for basic gravity wall construction. The 12º setback delivers great leverage, performace and stability. AB Stones are the most efficient, easy to stack, full size
blocks on the market.

AB Classic
For a perfect blend of performace and style, choose the AB Classic. With built-in 6º setback, the AB Classic stacks beautifully and creates a fluid finish for every wall.
