The Buffelsdraai Landfill Lining Installation project began at the end of March and we are now passing the critical 'spine' of the cell. Ramtar Construction was contracted by Melki Civils and Plant Hire to install the Geosynthetic Clay Liners (GCLs) as well as supply and install the geotextile protection layer over the HDPE.
Challenges include coordination between 3 contractors working in the same space, as well as keeping a sharp eye on the sky as the GCL must not get wet in the rain and has to be covered pronto if there's a downpour - cricket pitch style! With 31500 sqm to cover, we have found our rhythm and the team has come together nicely. Here's hoping for good weather in the next couple of weeks!

Ramtar Construction were recently approached by ShreeProp, a large Durban based property development group, to install subsoil drainage in a new warehouse facility in the Southgate Business Park. The property was continually flooded with groundwater and a solution was needed to ensure that the layerworks for the pavements at the rear of the building would maintain their integrity. Ramtar Construction installed innovative flownet cut-off drains on the perimeter of the building and are currently installing a herringbone system of subsoil drains over the rest of the area. The rain over the past months has not helped and site conditions are challenging to say the least!
The completion of the Strelitzia School Science Hall in Ispingo, officially christened the "Golden Pond 67 Science Centre" marks a milestone for Ramtar Construction this year. The 180 square meter hall is a learning facility dedicated to science, chemistry and computer science and boasts a 60 seat lecture and demonstration hall, a computer LAN, office and storeroom.
 Construction of a "Loffelstein" type retaining wall in Panorama Park Estate, Winklespruit. The actual wall uses an equivalent approved retaining block called Terrace Bloks.
The retaining wall has been engineered for a 3.2m maximum design height and a minimum radius of 2m. Challenges on this project include a constantly varying wall height and a small radius curve. The construction of the Kingfisher and Francolin dams at Simbithi Eco Estate was completed on the 22 July 2011, just in time for another bout of heavy rain over the weekend that helped to fill the dams. Ramtar Construction lined both dams with Geosynthetic Clay Liners (GCLs), which is a specialist lining product.  Kingfisher Dam After some set backs due to the unseasonally heavy rain storm we experienced in June, we are back on track with the lining installation to the dams at Simbithi Eco Estate. Below are some pictures of the lining installation.          Ramtar Construction has been appointed to construct the earthworks and dam linings for two ornamental dams at Simbithi Eco Estate. The project involves preparing and lining 4900 sq.m of dam floor area and will incorporate Geosynthetic Clay Liners (GCLs) as the barrier material. Commencement date: 20 April 2011.
