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

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)

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

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
