"By leveraging the inherent advantages of precast concrete and through extensive research and
development, we have sourced and created alternative solutions that will go a long way to provide
innovative, durable and cost effective solutions to solve common construction and infrastructural
problems," said Rocla's managing director, Trevor Barnard, at the launch event.

Rainwater Harvesting Solutions
Rocla will manufacture a range of rainwater harvesting tanks for residential, community and
municipal deployment that will play a role in solving sanitation and water challenges by capturing
clean rainwater and storing it safely underground for future use. In collaboration with the local
license holders of the ecoTechnic® range of rainwater harvesting accessories from Alltrap
Engineering in Austria, Rocla will introduce their full range of systems to the Southern African
market.

The concrete tank is installed underground where it is able to capture large quantities of water from
roof and parking area runoff. The design includes a filtering system, pump and other items on the
inside to ensure effective delivery of safe water for general grey water applications. Tank sizes range
from 3000L to an unlimited volume allowing for thousands of kilolitres of stored water with uses
varying from average households to school storage below fields and commercial applications below
parking areas.

"The concrete tank range," explained Justin Kretzmar, Rocla's sales engineer in charge of new
products, "is robust and will support cars driving over it in a parking lot application, avoiding the loss
of valuable above‐ground space and effectively addressing some sanitation challenges, whilst
conserving potable water."

Precast Wingwall for Infrastructure
Rocla has identified the need for more cost effective and time saving solutions in the infrastructure
and construction industry and is the first concrete manufacturer in South Africa to offer a complete
range of precast wingwall units to the market. These units have applications in both culvert and
stormwater installations to ensure maximum hydraulic flow performance at both inlets and outlets
of these structures.

The units can fit a wide range of pipe diameters, as well as rectangular culvert sections and consist
of two parts, namely the headwall, wingwall and apron, which is cast in one piece, and a separate
precast concrete toe that keys the unit to the ground for extra stability against impact loads.

Kretzmar added, "The benefit of utilising these units during construction is that it is made of a high
strength concrete mix which reduces quantities of materials, leading to a more cost effective
product made of superior quality and with a more efficient installation process than the current insitu
options. The units eliminate the need for formwork, site‐mix concrete and reinforcement
required on site, resulting in guaranteed quality and the prevention of delays due to curing or
stripping and with limited waste or clean up."

"With the traditional method, the structure is cast on site and the concrete needs a minimum of 24
hours to set before any formwork is removed, making installation a two to three day process. With
the Rocla units, the installation of the wingwall units takes less than 30 minutes."

Vehicle Restraint Systems
Another innovative product that Rocla will manufacture under licence is the Rebloc road barrier, the
latest European innovation in vehicle restraint systems, which can make road‐work zones safer and
increase the general level of road safety on South African roads.

The Rebloc systems offer permanent and/or temporary barrier separation on the sides and middle
of roads or placed as required during road works. With no loose parts, the barriers allow for quick
and accurate installation as the patented coupling (fastening component) is fixed to and protrudes
from either side of each element.

According to Kretzmar, these barriers can provide a safer option to SA roads and are a low
maintenance and cost saving solution.

"These barriers are also suitable for many other applications and environments, such as security
barriers protecting people or assets, control of mudslides at the base of mountains, prevention of
illegal dumping, blocking entrances to areas with health and safety access requirements and as a
fast, temporary or permanent and cost effective way to separate bulk materials or minerals," he
added.

Other Precast Products
Rocla has also secured the license from a UK based company to manufacture their full range of high
security and retaining walls which have been successfully used in UK, France, Ireland and USA for up
to 12 years. These walling systems consist of large concrete blocks in specific shapes from heights of
1.2m up to 3.65m. Also in association with the ecoTechnic license holders, Rocla is introducing a full
range of oil and grease separators meeting the highest European specifications for such products.

Barnard concluded, "The response to our new portfolio of precast concrete products has been well
received so far, and we look forward to providing cost effective, durable and robust solutions that
maximise the inherent qualities of the material in a wide range of applications. This diversification of
our product range and related investment bodes well for our group as it introduces a new income
stream that assists to combat the recent slowdown of infrastructural and construction projects in
South Africa."
