BURSTPACK™
BURSTPACK is a proven method of permanently sealing dead annular space between Tier 1 metallic pipe and inserted PE. It is quick and easy to deploy, taking less than a minute to mix and apply.
BURSTPACK consists of SVI’s two part expanding foam formulation, contained within a specially designed plastic sachet, featuring a series of chambers separated by ‘burst seals’. These allow the resin and hardener to be mixed within the sachet by bursting one of the seals, then inserting the complete, mixed sachet, into the annular space inside the pipe. A secondary ‘burst seal’ ruptures when the foam has sufficiently expanded, allowing the foam to seep out and fully seal the annular space. The application requires little space, reducing the size of excavation needed and can be inserted by hand or by using a specially designed long handled tool.
- Minimises Gas Migration: BURSTPACK effectively reduces the risk of gas tracking along the annular space.
- Prevents Surface Damage: Helps mitigate road surface slump and the formation of potholes.
- Blocks Ingress: Reduces the likelihood of water and waste entering the system.
- Easy Application: Simple to apply using SVI’s GIS:LC14 expanding polyurethane foam, delivered via a custom designed, self-actuating pouch.
- Flexible Deployment: Can be installed manually or with i-core long-reach tools.
- Rugged Packaging: Engineered for durability to withstand tough on-site conditions.
- Environmentally Friendly Design: New packaging is environmentally friendly, featuring reduced materials for less waste, easier application, and streamlined production.
