Allan Block Retaining Wall Systems

Colinwell works with their strategic partner, Allan Block, the world leader in segmental retaining wall block technology, to manufacture the Allan Block collection.

For almost 20 years Allan Block has been helping Architects, Engineers, Landscape Professionals and Homeowners realise the full potential of their environment.

The Allan Block collection allows easy design and quick construction of retaining walls to meet specific engineering and site requirements, while at the same time offering the perfect blend of performance, texture, colour, quality and lasting value.

Allan Block require only a compacted stone foundation and lock together without pins, clips or mortar. The front lip creates a built-in setback and the hollow core makes them easy to handle, easy to stack and promotes built-in drainage.
