![]() All of the ideas shown in these pictures can be created with Adbri retaining wall blocks. Along with our expert and technical advice, Adbri’s retaining wall ideas gallery is a great starting point for inspiration for your retaining wall project. You’ve come to the right place for retaining wall ideas for backyard landscaping. Manually digging deep post holes and setting posts in concrete to be plumb can be difficult for most DIYer’s. Our service team will contact you within one business day. While concrete sleeper walls are effective for retaining soil, they can be difficult to install as the posts need to be as deep into the ground as the wall is high. Get an online, no hassle quote for concrete, aggregates or concrete pumping services. Concrete sleeper retaining walls are superior to timber sleepers because they are very durable and won’t rot. ![]() Sleeper walls have a small footprint meaning they can be installed in areas where space is tight. Concrete Sleeper Retaining WallsĬoncrete sleepers are a popular choice for low height, pure vertical garden walls.

Some setback retaining wall blocks like Windsor Stone can be built to over 1 metre in height without reinforcement. The different types of retaining wall block systems can be built to varying heights. These concrete retaining wall blocks come in different shapes and sizes, they can either be vertical (they stack directly on top of each other) or setback (they “lean back” each course the wall gets higher). Segmental concrete wall blocks come in a range of colours including black and cream, and there are different block face textures available including the traditional split face block. These systems are installed onto a compacted road base levelling pad which is significantly easier to install than a concrete footing. Enter the length, width, and height into the calculator to determine the volume of the block core fill. Segmental retaining walls “stack” together without the need for mortar, concrete or glue. These retaining wall blocks are one of the best DIY retaining wall systems you can buy. Retaining wall bricks are used in a similar way using a traditional brick unit which is mortared together to create a wall. Due to the basic aesthetic appearance of the standard grey Besser® blocks, they will often be used only in applications where the wall will not be visible, or finished with render and paint on top of the Besser block. Besser® Block retaining walls are mortared together, installed on a concrete footing and often used for engineered and load bearing walls where the blocks will be core-filled with grout and reinforced with steel. Number of concrete blocks needed = 90 concrete blocksīy multiplying the core volume of a single concrete block by the number of concrete blocks needed to build the wall, we can then find the fill volume, as shown below:įill volume = core volume per concrete block × number of concrete blocks neededįill volume = 0.006424 m³ × 90 concrete blocksįrom our calculations above, we can now say that we need around 0.5782 m³ of concrete or mortar to fill the concrete blocks that we will use to construct our wall.Types of Retaining Walls Besser Block Retaining Wallsīesser® Blocks are a popular choice for soil retaining walls or when a wall is required to level sloped land. Number of concrete blocks needed = 7.2 m² / 0.08 m² Number of concrete blocks needed = (3.0 m × 2.4 m) / (0.4 m × 0.2 m) Number of concrete blocks needed = (wall width × wall height) / (block width × block height) Now that we have all the details we need, we need to divide the total wall area by the area of a concrete block to find the number of blocks our wall needs: The core volume of a standard size 6-inch concrete block is approximately 392 in³ or 0.006424 m³. As a sample calculation, let us consider building a 3.0-meter wide and 2.4 meter high wall using 6-inch thick standard 8" × 16" (20 cm × 40 cm) concrete hollow blocks.
