The Canyon Ledge profile has a rugged, layered look that mimics naturally weathered rock. Its texture and Varied stone shapes add dimension and a more organic feel to any wall. It Works well with Landscaping.
The Cut Sandstone profile features cleaner lines and a more uniform stone pattern. It creates a refined, architectural finish that suits modern or formal designs. This option balances natural texture with a sleek, structured appearance.
A hollow block measuring 610mm H x 1220mm W x 900mm D, Verti-Block is perfectly proportioned for the most popular types of landscaping projects, including gravity walls up to 4.5m high—even higher when reinforced. Its hollow design makes it affordable and easier to handle than solid blocks. Plus, Verti-Block is less labor intensive than small, hand-laid blocks and offers a more practical solution than a cast-in-place retaining wall.
Even more appealing, Verti-Block is incredibly strong and versatile thanks to its interlocking design. Featuring a male-and-female style connection, Verti-Block units ensure you’ll get a secure fit that guarantees the correct amount of setback on every installation. Verti-Block’s hollow design saves money by using less concrete and lowering transportation costs. It also ensures the right amount of crushed stone backfill. Experienced installers know that too much crushed stone wastes money—too little can build hydrostatic pressure and cause the retaining wall to fail.
Verti-Block was designed specifically for landscaping projects, making transport and installation simple and practical, even in tight or restricted access areas. The blocks can be moved and placed using smaller, more accessible equipment, so there is no need for large machinery like telehandlers or cranes. This makes it easier to work on residential sites, backyard projects, and areas where access is limited. It also helps keep installation efficient and manageable without overcomplicating the job.
The male and female interlocking system takes the guesswork out of placement by guiding each block into the correct position. This reduces the chance of installation errors and keeps the wall aligned as it is built. The result is a retaining wall system that provides reliable strength, accurate installation, and a clean, consistent finish on every project.
Now there’s an easy way to see exactly how your Verti-Block wall will look before you build it. SketchUp is a widely used modeling software by engineers, architects, and even homeowners.
Click HereWorks are underway on Trevallyn Road, where a new 21-metre retaining wall is being built to stabilise the road embankment and replace the existing stone wall. Project Engineer Daniel takes us through the project.
