The scope of this project is to design, trial and evaluate a new small pressure pot that has a capacity of 1.5 litre, is lightweight, easily portable, will reduce the injection process, and limit the amount of waste generated through material use and excavated material sent to landfill. If the small pressure pot proves to provide a more effective technique by which to seal joints, it will reduce the amount of joints requiring encapsulation and as a result the size of excavation and use of expensive external contractor resources.

This purpose of this project is to design a small lightweight pressure pot to be used in conjunction with the existing ALH Large Diameter Mainspray Injection Equipment.

In order to determine whether this project has been successful the following key milestones will be achieved:

  • Off site testing review and product verification of the prototype using specially designed test rigs with the results submitted to SGN for approval

  • Upon approval, the equipment will be field trialled across three of our network locations in Scotland, South and South East

  • Full product evaluation will be carried out to determine how this new product compares to existing techniques and whether it will provide us with the most cost effective solution for sealing joints

  • A practical demonstration for all GDN’s to observe the new equipment in operation.
