Why Choose Stonebloc? Traditional retaining wall systems such as timber, masonry, or gabion baskets are labour intensive, slow, and expensive. Stonebloc is leveraging tried and trusted engineering principles to revolutionise the retaining wall market. The secret to the Stonebloc system is the unique interlocking concrete block. Installation is straight forward, simply prepare the foundation (compacted gravel or concrete) and lay the blocks. The Stonebloc system is so efficient, two people can build up to 120m2 of wall per day. Finally, the cast in standstone finish on the blocks create a timeless aesthetic that will blend in with the surrounding environment.

Green Made from upcycled concrete, Stonebloc is  New Zealand’s most sustainable building material. Fast Stonebloc is the fastest retaining wall system on the market – build up to 120m2 of wall per day. Engineered 400mm thick, solid concrete walls sit at the heart of our engineered system. Affordable Our scale and unique manufacturing process ensures we deliver green building at affordable prices. Timeless The block’s country manor style sandstone finish creates a timeless beauty.

A Truely Sustainable Product The New Zealand Ready Mix Concrete Industry generates an estimated 260,000 tonnes of waste concrete annually. Thats enough concrete to build seven Sky Towers. Stonebloc has partnered with Envirocon to upcycle this concrete into our unique retaining wall system, making Stonebloc New Zealand’s most sustainable building product. By doing this we’ve diverted over 70,000 tonnes of concrete from landfill. In the process is conserving precious resources, decreasing carbon emissions, and creating sustainable jobs. Crucially this process reduces costs, meaning a Stonebloc wall can be up to 33% less then traditional retaining wall options. Quality Is Paramount The Concrete used to manufacture Stonebloc  is exactly the same as that used for buildings  and infrastructure. Each block has a unique serial number cast into it so you can track concrete used to manufacture that block back to when it was first batched. Comprehensive grading on all blocks to ensure uniformity and consistancy.
Envirocon is a Product Stewardship Scheme accredited by the Minister for the Environment under the Waste Minimisation Act 2008. The Scheme provides a sustainable end of life management solution for ready mix concrete waste. It is the  only accredited construction related scheme. The aim of the Scheme is to eliminate all waste created through the concrete batching process – that is, wet waste ready mix concrete, washout fines, and waste water. The Scheme specifically excludes demolition waste concrete. Upcycling is a key prinicple of the Envirocon Scheme. Envirocon achieves this by capturing wet concrete and turning it into useable precast concrete products – like Stonebloc. Through upcycling, Envirocon can help create a more sustainable construction industry.
Unique interlocking design provide a sheer key in both horizontal directions. It mean’s Stonebloc’s stronger for longer.
Reinforce the wall post install by inserting steel bars through holes in the blocks.
Our comprehensive quality control system delivers true to size blocks, consistent in colour and texture.
Each block weighs 300kg, measuring 400mm wide, 400mm high, 800mm long.
Certified central lifting anchor allows ease of movement and efficiency in installation.
