CRS wins at the CMA Awards, 2006

This year’s Concrete Manufacturers Associations (CMA) Awards ceremony took place at the Sandton Convention Centre in Johannesburg, on Saturday, 7 October. Terraforce, Cape Town based and international licensor of erosion control and retaining wall blocks, and Klapmuts Concrete/Cape Retaining Systems, manufacturer of Terraforce blocks in the Western Cape, managed to secure two national and two regional awards in the Retaining Wall Elements category, as well as being awarded a Premier Award, one of four Cathay Pigments trophies.

During the black tie gala banquet, that was attended by over 450 guests, the Inland Regional, the National and the Cathay Pigments Trophy winning project teams in this year’s CMA Awards for Excellence competition were announced.

Attending the function were CMA companies, the judges and the media. The MC for the evening was well known comedian David Kau and the awards were presented by Garth Gregory, president of the CMA and Terrence Yu, chairman of Cathay Pigments SA.

The Trophy awards are made to project teams for the most outstanding submission in each of four product groupings, Concrete Block Paving, Concrete Masonry, and Concrete Roof Tiles. The best project from the three remaining entry groups, Infrastructural Products and Innovative Products, Concrete Retaining Block Walls and Suspended Concrete Floor Slabs, is selected by the judges for the fourth Trophy award.

This year that trophy went to Terraforce cc, Cape Town based and international licensor of erosion control and retaining wall blocks and their Western Cape manufacturer, Klapmuts Concrete/Cape Retaining Systems, with the judges recognising the “innovative and ecological” style in which the Terraforce L12 rockface blocks were applied in a highway noise barrier installation at a new development in the Western Cape.

This new development within the Century City complex in Cape Town is located next to a busy thoroughfare. To protect residents from noise and ensure their privacy, a six metre high, 500m long earth berm was created with surplus site material.

The noise barrier, designed by Planning Partners (Pty) Ltd, Cape Town based landscape architects, was constructed by Decorton, Cape based Terraforce contractor, using Terraforce L12 rock face blocks placed on a concrete foundation for each terrace. A subsoil drainage system is located behind the bottom row of blocks and the earth backfill is reinforced with Polytex 115 geofabric on every third row of blocks.

To further improve noise absorption, an embankment with three terraces, each with a maximum height of 1.8m and varying widths, was built on the road facing side. Hardy plant varieties were introduced to prevent wind erosion on the sloping embankments facing the buildings.

To finish off the overall look, Real Landscapes, Cape Town based landscaping company, used the terraces to good effect by creating almost instant hanging gardens with (mostly) water wise indigenous planting.

Says Rust from Terraforce: “These hardy plants are fast growers and adapted to dry spells and high winds that can occur in this part of South Africa. They will also be very effective in preventing wind erosion on the sloping embankments, facing the buildings.”

Another interesting project by Klapmuts Concrete/Cape Retaining Systems - a private home in the Western Cape - was awarded a regional and national award for the Coastal region.

Situated in Welgedact, this house required a landscaped desert image requiring little or no irrigation and minimal maintenance. To achieve this goal, the embankments above and below the paved driveway were stabilised with Terraforce L11 rock face blocks in a rustic sandstone.

Two separate terraces were incorporated to accommodate feature plants while behind the house another rock face wall was built to provide additional space around the kitchen and pool area. The judges felt that this stylishly landscaped retaining wall complemented the overall architectural form of the house in a very effectual manner.
