The Shaft Plug V.S.S. (void sealing system) has been specifically designed to provide the user with a product that gives emergency and short term sealing of an Intake or Exhaust shaft.

 

This product provides you with an emergency seal of the shaft when the permanent cover has been compromised (or simply needs replacing),  or when other infrastructure is to be connected. It may also be used as a pre-cover or shaft pentice. The Shaft Plug is available with or without a Venting tube, in Standard or FRAS fabrics and is re-usable.
 

The Shaft Plug can be installed remotely using a long boom crane, this makes it the safest, most efficient and cost effective alternative for your shaft collar construction or maintenance requirements.

Venting Tubes are designed to specific requirements and are correlated with Shaft Plug design to ensure that build up of Air/Gas pressure from the Underground source on the Shaft Plug can be safely and efficiently drained away. The Gas/Air is removed from the area via a lay flat ducting tube and may be connected to a flow measuring and non return valve or fusible link shutoff system, and into a EOL flame arrestor. 
 

The Shaft Plug is also suitable for Horizontal or Inclined application and can be designed to specific insitu  requirements.
