A custom-designed Kaytech drainage system has played a fundamental role in the multi-million Rand renovation of a Free State soccer stadium. Although the Seisa Ramabodu Stadium in Bloemfontein was used as a training field during the 2010 Soccer World Cup, in 2011 the ground was deemed unsafe by the Premier Soccer League (PSL) and the stadium subsequently demolished.
Kaytech’s Werner du Plessis specified Kaytech’s bidim A5 and Megaflo 300 to provide the most effective drainage system for the new sports ground and Southern Turf Management, whose portfolio includes sportsfield maintenance and construction was contracted for the installation.
Bidim is a high performance, continuous filament, nonwoven, needlepunched geotextile manufactured from 100% recycled polyester. Significant advantages are gained from the process of needlepunching including an appreciable thickness, high porosity and an excellent drainage capacity. Since bidim provides the highest possible throughflow rate in conjunction with exceptional filtration characteristics, there is no better product for sportsfield drainage.
Megaflo is a geocomposite panel drain system comprising an HDPE core completely wrapped in bidim for optimum filtration. The many benefits provided by Megaflo include a formed invert at the bottom of each panel preventing loss of water into base soils, a minimally restricted open waterway and a high crush resistance.
For this project, a parallel drainage system, similar to a truss layout, was created by placing a layer of bidim A5 (10 000m2) over which Megaflo 300 (2300m) was installed lay flat. Fittings for the Megaflo system were custom-made by Kaytech. Both products are suitable for a variety of applications and easy to install. The high tensile strength of bidim provides resistance to puncture, tearing and burst while its flexibility proves advantageous during installation. To complete the sportsfield, the drainage system was covered with a 19mm layer of stone gravel followed by a 300mm final layer of suitable grow medium.
The high performance of these Kaytech products provided the Free State Department of Sport, Arts, Culture and Recreation with a cost effective, durable drainage solution for the new Seisa Ramabodu Stadium, whose complete revamp now meets FIFA standards.
