Contract Summary • Contract No. CES 14/2015 • Client: Drakenstein Municipality • Engineers: Lyners • Main contractor: Vakala Construction • Specialist geotechnical contractor: Franki • Contract Commencement/completion: August 2016 – Feb 2017 • Scope of specialist geotechnical work: 215m 1780ø O.D. Pipejack; 250 m³ Grouting

Treated jacking face holding cobbles and fines in suspension.

also well-known for its soil improve- ment systems including dynamic compac- tion, deep soil mixing, accelerated con- solidation and of course Jet Grouting as discussed above. Franki’s skills in trenchless technology are just as strong and for more than 30 years it has successfully provided pipe- jacking and other trenchless technologies – augering, thrust boring and large diameter

case boring – to a wide range of clients in Southern Africa. Trenchless technology is a ‘family’ of methods, materials, and equipment capable of being used for the installation, replacement or rehabilitation of existing underground infrastructure with minimal disruption to surface traffic, business, and other activities. It is, therefore, often the most cost-effective solution.

Pipejacking, an integral part of this ‘family’, is a technique for installing underground pipelines, ducts and culverts. Powerful hydraulic jacks are used to push specially designed pipes through the ground behind a shield at the same time as excavation is taking place within the shield. The method provides a flexible, structural, watertight, finished pipeline as the tunnel is excavated. 

Online CPD-accredited lectures Kaytech has launched a unique service offering: Online CPD lectures on geosynthetics. Industry professionals can now ‘attend’ the lectures, accredited by SAICE, whenever and wherever they like – from the comfort of their own office, home or even waiting to board a flight.

Conducted by renowned geosynthetics expert, Peter Davies, these lectures make earning CPD points more convenient and keep one up to date with the latest technical and regulatory information about geosynthetics. For those who don't need to collect CPD points, these are informative and easily accessible lectures that impart current information on geotextile installations, and are thus worthwhile viewing for their practicality. To earn CPD pointswatch the lecture at: www.kaytech.co.za/cpd, complete a short online questionnaire and download an attendance certificate. Plus, these online lectures are free of charge and won’t even cost the extra time to reach a venue. Each lecture earns one 0.1 CPD points. There are seven lectures, each divided into segments of 15 to 20 minutes, so they can be viewed in short bursts or

a full lecture completed in one sitting; whatever is convenient for the viewer. The lecture series comprises: • Introduction to Geosynthetics • Filtration and Drainage with Geosynthetics • Erosion Control with Geosynthetics • Soil Reinforcement with Geosynthetics • Lining Systems with Geosynthetic Clay Linings (GCLs) • Bitumen Based Formed In-Situ Dam Lining with Geosynthetics • Road Pavement Maintenance with Geosynthetics Kaytech will continue to offer live lectures, delivered by Peter Davies who, with 50 years’ experience in the industry, provides an invaluable perspective in these presentations. Customised lectures at your own premises can be arranged directly with your nearest Kaytech branch or via this
