Efficient stormwater drainage solutions

The Beany Block

Ineffective drainage causes a multitude of issues when areas such as roadways, parking lots, walkways and areas around buildings become swamped with large volumes of non-dispersing water. The Beany Block from Technicrete – a member of the ISG Group- is an efficient and practical solution for effective drainage due to its large flow capacity/unit weight ratio, making it a more cost-effective solution than conventional kerbing and drainage offerings.

The Beany Block system comprises a series of base blocks of standard channel section and Top Blocks of inverted channel section with an opening in one side face. When laid end to end they form a combined kerb and surface water drainage unit that is strong enough to withstand normal traffic loading.

Each standard top and base block is 500 mm in length and weighs approximately 85 kg.They have also been designed to withstand accidental 80KN axle loading. The top block oval openings provide for greater inlet capacities compared to conventional kerb inlets. Standard blocks can be used for curve radii of 30 mm or more. ‘Splay’ blocks are available to meet specific requirements with a radius of between 6 m and 30 m.


When the Beany Block system is utilised no long drainage sections are required to be specified in contractual documents. The system can be substituted for kerbs, stormwater pipework, kerb inlets and parts of footways. Damaged services are less likely to occur when installing the Beany Block due to its simple and practical design and installation.

Some of the traditional problems experienced with conventional drainage that the Beany Block system eliminates include: insufficient fall; conflicting levels of service mains and cables; ponding adjacent to low points; traffic safety and control on existing freeways.

Additional cost savings can be achieved on projects that have wide freeways and footways; freeways that have ‘flat’ longitudinal falls; rock in sub-grade; shallow outfall and existing services or foul drainage at conflicting levels.


The Beany Block has been designed for use in conjunction with SABS Fig. 3 and Fig.4 Barrier Kerbs. The Beany produces 400 mm length of inlet opening for every 1 m of kerb. The system can be used in any application where high inlet capacity is required; wide freeways; parking areas; taxi ranks and bus depots; wash bays and vehicle service areas; median islands; industrial areas; drainage around buildings and walkways and toll plazas.

Rocla’s Stormwater pipes

Effective stormwater management can prevent pollution, flooding, erosion and damage to the environment and infrastructure. Therefore, it makes financial sense for local municipalities to invest in products and technologies to ensure that the quality of infrastructure, be it stability and sustainability of both the built and natural environments is not compromised.

Within its range of products, Rocla – also a member of the ISG Group, manufactures stormwater pipes with both interlocking and spigot and socket joints in a range of strength ratings. The spigot and socket joints utilise the rolling rubber ring principal where no installation lubricant is required. All pipes conform to the SANS 677 standard.

After consultations with Rocla’s technical team, interlocking joint pipes were selected for installation at the Great North Plaza in Limpopo, whilst the Borwa project in Westonaria selected Rocla spigot and socket joint storm water pipes. Technical support from Rocla ensures that correct product and technology is selected with consideration for the financial constraints of each project.

Technicrete is part of the IS Group of companies which includes Ocon Brick and Rocla.
