A safety hazard on the N4 highway in Mpumalanga has been overcome with the installation of Technicrete’s Beany Block combined concrete kerb and drain system.
Heavy rains in the hilly sections of the N4 frequently closed the highway between Belfast and Wonderfontein as stormwater flooded across the road. The Beany Blocks now installed down the middle of the highway act as a catchment channel for the overflow and form a practical middle island, effectively creating a safer, dual-lane highway.
About 14 000 Beany Blocks were installed at intermittent stretches over some 13kms of the highway. Installations began in late 2008 and today the Beany Blocks are functioning effectively.
The Beany Block system consists of a series of standard channel section base blocks and inverted channel section top blocks, with an opening in one side face. Laid end to end, they form a combined kerb and surface-water drainage system strong enough to withstand normal traffic loading.
