All new properties developed in the Ekurhuleni region, regardless of the size, are required to submit a storm water management plan to the Ekurhuleni Municipality. To meet this prerequisite, the consulting engineers, Mhiduve (Pty) Ltd, developed an innovative storm water attenuation management system through the use of Technicrete’s Aqua Zig Zag Sustainable Urban Drainage Systems (SUDS) and DZZ interlocking pavers on the new Columbia Pharmaceutical factory development in Boksburg, thereby enabling it to meet local authority requirements.

Deon Slabbert, Project Engineer from Mhiduve (Pty) Ltd, commented “We believed that the successful management of the storm water element at this new factory required an innovative approach due to space challenges we faced on site. In addition to permeable paving used as a covering for attenuation ponds, we used Technicrete’s DZZ 80mm interlocking pavers over areas of 3,000m2 and 1,200 m2  respectively below the permeable paving that had capacity to hold 1,600m3  of storm water.

We also sourced 4,300 m2 of Aqua Zig Zag 80 mm Class 40/2.6 pavers. The DZZ pavers were coupled with 2-4 mil of filler stone that was used as grout in the system.”

“The DZZ paving blocks are in fact ‘slotted’ paving blocks, which allow the storm water to penetrate the surface through these slots and be collected in the unique layerworks underneath the paving surface from where it can be released in a controlled manner into the system of the local authority. The SUDS that were supplied by Technicrete are increasingly being used to prevent run-off and flooding, as well as a method of collecting, attenuating and cleaning storm water” said Slabbert.

Technicrete Sales Representative, Wayne Oliver commented “SUDS are increasingly being used to prevent run-off and flooding, and as a method of collecting and cleaning storm water.

It is an interesting and successful use of our DZZ range of interlocking pavers for an application as crucial as storm water attenuation management that was a critical component of the Columbia Pharmaceutical factory development. The combination of the DZZ with the Aqua Zig Zag and filler stone established a good permeable paving system suitable for the dispersion of the quantities of storm water expected.”

The Technicrete sustainable urban drainage system allows heavy rain to infiltrate through a permeable concrete block paved surface into a unique sub-base before being released in a controlled manner into sewers or water courses. The paved areas must be firmly restrained and Technicrete kerbing was utilised for this purpose on this attenuation project.

“The DZZ offer a hard wearing surface overlay for traditional applications such as commercial and industrial roadways, depots, suburban streets, petrol station forecourts as well as residential driveways and pavements” said Oliver.
