  1. Groupe Marais We build Tomorrow's networks

  2. Key figures • 49 years' experience • Over 100 employees • 40m€ turnover in 2009 • 30% of turnover generated abroad • 30 000km of telecom and energy networks installed over 10 years in Europe, Africa, America, Asia and Oceania • 5% of turnover invested in research and development every year • Subsidiary in Algeria, Morocco, Tunisia, South Africa, Australia, Middle East, Malaysia

  3. Key figures • 2,500 km in West Africa (Gabon, Guinea, Sierra Leone, Mali, Burkina Faso) • 6,000 km in the Maghreb (Morocco, Algeria, Tunisia, Libya) • 3600 Km in Europe • 1,500 km in South America (Colombia, Brazil, Ecuador) • 4,800 km in Central America (Cuba, Mexico, Santo Domingo) • 2,500 km in North America(Canada, USA) • 500 km in the Middle East (Saudi Arabia, Yemen, Lebanon) • 1000 km in South Africa • 300 km in Australia

  4. Marais technologies Experience and capabilities Mechanical Laying • Trenching • Cable laying • Backfilling

  5. Marais technologies Experience and capabilities 9 cm Flexibility 1,3 m 60 cm 2,5 m 850- 1300

  6. Key aims of Marais technologies The mechanical laying with the Marais wheel: Advantages against a traditional laying process Increase Work Quality • Continuous screening of the trench: the layer • Keeps the geometrical features of the trench • No material falling while the network is being laid • No decompaction of the surrounding ground • Quality of the trench bottom: the shoe

  7. Key aims of Marais technologies The mechanical laying with the Marais wheel: Advantages against a traditional laying process Increase Work Quality • Laying quality of the network • Constant depth; the wheel cuts both hard and soft materials • Constant altimetry and planimetry during the laying of the network • Compliance with the admissible bending radii all over the laying operation • Compliance with the cover (constant load applied to the network)

  8. Key aims of Marais technologies The mechanical laying with the Marais wheel: Advantages against a traditional laying process Increase Work Quality Constant and reduced width of the trench • Constant metric construction cost • Less materials to be excavated • Less materials to be backfilled and compacted • Reduced repair of the surface

  9. Mechanical Laying • Laying Box

  10. Chain trenchers Deep trenches • Machines dedicated to wide trenches opening • All machines have a conveyer • Easy reuse of the excavated materials • Same machine in soft and hard soils • Could be adapted to mechanical laying • Control of the quality of the trench

  11. Average Output : 800 – 1000 meters per day
