Armorflex 165, Technicrete’s erosion control system
that provides an alternative for a wide variety of erosion control and drainage
projects, was specified for the recently completed attenuation pond for EnviroServ
at their Rosslyn premises.
Armorflex blocks offer an excellent lining for
drainage channels. At aprons at pipe inlets and outlets, Armorflex eliminates
pipe undercutting that can lead to severe problems such as surrounding bank
failure and siltation downstream.
The Rosslyn project ran from February to June 2019 and
was undertaken by MK Africa Civils. “We have worked with MK Africa Civils on
other projects, and we understand that at times, all does not run smoothly on site.
Upon excavation of the pond’s designated area, unexpected rock was discovered
which had to be removed with chemical blasting before the required pond level
could be reached. We halted deliveries of the Armorflex 165 loose blocks to
site until the blasting issue had been resolved” said Luan van der Berg, sales consultant
for Technicrete.
“We supplied 7,000 m2 of Armorflex 165
blocks for the attenuation pond which will serve as a storage for run-off dump
water and any other excess water components at site. The product was supplied
in palletised loose block form for manual installation, which upon completion
formed the Armorflex mat formation.
“The beauty of the Armorflex system, is that it is
flexible and sophisticated in design, conforms to ground contours (even if
settlement occurs after installation and the blocks have a specially tapered
design to allow for this flexibility), settles without fracture, and requires
only limited ground preparation,” Van der Berg concluded.
Technicrete manufactures the Internationally Licensed
Armorflex system in South Africa. It is the only system available locally with
the facility to wire tie adjacent blocks together into long mats. The
interlocking design allows the surface to remain flexible to movement,
eliminating the cracking and spalling issues that plaque solid concrete
surfaces, even when exposed to regular inclement weather. The openings in each block
and between blocks are perfectly sized to benefit from enough vegetation growth
to make the surface appear ‘natural’ whilst still maintaining structural
integrity.
Amorflex is suited to other drainage applications such
as ditch linings, spillways, headwalls, sediment basins and traps, pipe inlet
protection, and protection of barriers.
Technicrete and Rocla are part of the Infrastructure
Specialist Group of companies (ISG).
