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

Product Description

For almost 30 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.

A selection of colour swatches can be viewed below and our full brochure which details all colours, blocks and sizes, including technical information, can be downloaded in PDF format from the link on our downloads tab. More information can also be found on Allan Blocks own site.
