Allan Block Retaining Walls

Bowers Retaining Systems Ltd is a sister company of Bowers Brothers Concrete and the proud licensee for the Allan Block in New Zealand.

The Allan Block success began 25 years ago with the introduction of its patented segmental retaining wall product – The Original Allan Block, and its mission is to supply the world with innovative alternatives to traditional concrete construction.

Allan Block stacks beautifully and creates a smooth and fluid finish for every wall, bringing a refined look of classic natural beauty to any landscape. It is easy to lay, durable, cost effective and best of all, looks great.

Expect high performance with the only retaining wall system in the world that has been seismically tested.


Bowers Retaining Systems Ltd is committed to meet customer needs and expand its existing offer with the introduction of the AB Ashlar Blend, a sophisticated approach to distinctive landscape design.
