AG’s latest walling innovation Diamond Pro® Air – a revolutionary lightweight retaining wall solution that seamlessly blends strength, sustainability and simplicity.

Weighing just 24.5 kg per block, Diamond Pro® Air is our lightest 200mm high retaining wall block to date. Its innovative structure incorporates large voids to significantly reduce weight, while optimising strength, making it capable of supporting engineered walls up to 3.6 meters high.

Designed with efficiency and performance in mind, Diamond Pro® Air features a near-vertical less than 4° wall face for a modern aesthetic and optimal land use. Its hollow core design not only makes each unit lighter and easier to handle, but also enhances drainage performance- ideal for high-performance retaining wall applications.

This intelligent solution maximises usable space, reduces labour strain, and minimises land waste, making it the smart choice for engineers, landscapers, and contractors.

This lightweight range offers a premium aesthetic at a cost-effective price, providing impressive savings to our other walling options. Its innovative design includes locator lugs that simplify installation, ensuring a secure interlock between blocks while eliminating the need for costly metal pins, helping you stay within budget.

The ideal walling system for house builders, creating rigid, durable plot divisions. Using no-fines concrete, it fills voids around posts and behind blocks, providing strength, stability, and built-in drainage.

When built in stretcher bond, the system can accommodate light fencing (subject to design). Additionally, the blocks allow drainage to be incorporated directly within the block, making them ideal for low-height gravity walls.

Available in a Stone Cut™ finish in a variety of warm earth tone colours.

Preliminary designs from our in-house team, including 2D layouts, quotes, material breakdowns, and technical advice.
Maximise every inch of space with the optimised less than 4º batter design, ideal for compact installations. Its built-in anti-climb features enhance safety, helping to minimise the risk of accidents.
Features large thru-cores that align vertically from course to course, enabling easy filling and smooth integration with light fencing.
This near-vertical finish creates a setback of just 25.2cm over a 3.6m wall, compared to competitor blocks with a 7º batter that push walls up to 19cm further into your land.
The Split Face finish uses patented technology to create a ‘naturally textured’ finish.
Mortarless and pinless – built with no mortar or concrete, the unique dry build locking system allows fast track construction in all weathers. This means quicker installation rates than traditional brick and blockwork.
One-man lift capability allows a single worker to efficiently place each block, effectively doubling productivity compared to heavier alternatives, lowering labour costs.
Features a patented locating lug that acts as a guide to ensure accurate alignment and precise set back every time.
For convenient capping, the top course can be installed upside down, simplifying the process.
The capping block has a smooth finish and is shaped asymmetrically (tapered), making capping straight or curved walls much easier.
AG recommend affixing Cap Blocks and Corner Blocks using a suitable concrete adhesive.
