Bosun Buffalo Block

Buffalo Block Features and Benefits:

Geometry

The unique geometry of the Buffalo Block is designed with a complete interlock ability in mind, while ensuring application versatility, structural integrity and installation simplicity. With an industry leading Movability factor, the Buffalo Block ensures a stable matrix of blocks which can resist the destructive forces bought on by high velocity water-flow.

The voids and the unique surface texture of the block are engineered to provide the required flow resistance. In order to achieve the most stable orientation, it’s recommended to install the blocks with the “nose” of the block pointing upstream.

The smaller, segmental design of the Buffalo Block creates a more flexible surface which is less prone to damage caused by the movement of the ground beneath it. Due to this compact design and 100mm thickness, the Buffalo Block has a higher load-bearing distribution and capacity when compared to traditional grass blocks and larger concrete paving elements. In addition, the design ensures that the block is easier to handle and install.

Nibs

The Buffalo Block features specially designed, patented nibs, which ensure adequate and uniform joint widths between blocks. This prevents edge and corner spalling commonly experienced with traditional grass blocks when under load. The taper on the nibs creates a flexible surface which is less prone to damage caused by movement.

Furthermore, the nibs allow for easier installation on uneven surfaces. Less surface preparation is required as the taper of the nibs ensure the blocks maintain interlock ability while following the earth’s contours. Patent: ZA 2019/06463

Permeability and Vegetation Growth:

The voids in the Buffalo Block allow for the ingress of water, growth of vegetation and the infill of concrete on specific installation designs. The size of the openings per block are 40mm x 40mm. In addition to these openings, the nibs space the blocks apart – further increasing the permeability of the installation. Once installed, they amount to approximately 20,5%/m².

The growth of vegetation in and around the blocks creates a natural look that blends into the surrounding environment, making it ideal for drainage channels, embankment stabilisation and grass block installations.
