Diamond Pro® Air
Transform Your Garden with Ease
Diamond Pro® Air offers the perfect solution for homeowners seeking stylish, durable, retaining walling that’s remarkably easy to install. Each block weighs just 24.5 kg, making it lighter to handle without compromising the strength needed to support walls up to 1m (3.28ft) high.
Designed with convenience in mind, its innovative locator lugs create a secure, mortarless interlock—no messy adhesives or complicated fittings required. Whether you’re building it yourself or working with a professional, installation is quick and straightforward.
Featuring a rustic split-face finish in a selection of warm earth tones, Diamond Pro® Air brings timeless charm to any outdoor space. Proudly made in the UK with 100% renewable energy and locally sourced aggregates from our own quarry, it’s a sustainable and stylish choice for transforming your garden effortlessly.
