Infrastructure - Specialises in Microtunnelling and Shaft Sinking

Winslow Infrastructure is a division of the Winslow Group that specialises in microtunnelling and shaft sinking operations throughout Australia and New Zealand.

These trenchless techniques serve all aspects of the Civil Engineering Industry including facilities for potable water, stormwater and sewerage systems,  gas pipelines, underground cables and ducting.

Based in Melbourne, Winslow Infrastructure and have been in operation for over ten years, offering a range of Trenchless solutions to various projects throughout Australia.

The specialist techniques used by Winslow Infrastructure ensure that a range of tunnelling operations can be carried out between 250mm and 4000mm in pipeline diameter and shafts sunk as large as 25m in diameter up to depths of 35m.

The principal methods of tunnelling used are:

• Guided Boring Systems for pipelines up to 800mm in diameter,
• Microtunnelling and Pipejacking for pipelines between 800mm and 4000mm in diameter.
• Auger Boring for pipelines up to 1500mm in diameter.

The principal methods of shaft sinking are:

• Underpinning & Caisson construction using precast segmental linings,
• Cofferdam construction using piling techniques.

During its development Winslow Infrastructure has established a large fleet of Trenchless plant including mts Perforator Slurry Tunnel Boring Machines, Schauenburg Separation Plants, American Auger Boring Machines and all associated plant to support these operations.

Winslow Infrastructure also has the full range of shaft sinking plant for the construction of precast segmental shafts ranging from 3.66m to 25m internal diameter.

Throughout its 25 years in the industry Winslow has built up a diverse portfolio of successfully completed and current civil construction projects.
