Blast Hole Liners

PVC WELDING SERVICES

Engineered PVC liners for drill and blast operations

In drill and blast, compromised liner performance can impact the performance of explosives and disrupt the engineered energy distribution profile, potentially resulting in rework, remediation and production downtime requirements that can significantly hinder mining operations.

PolyFusion manufactures PVC blast hole liners designed to control water ingress and maintain charge column integrity. Controlled in-house production, monitored welding processes and tight dimensional tolerances underpin reliable installation and repeatable results across production cycles.

Each PVC liner is fabricated to support predictable blast outcomes and consistent site performance, helping ensure blast designs perform as intended.

controlled in-house automation

Production consistency for reliable field performance

All PVC lining products are manufactured in-house under controlled production conditions to ensure consistent quality and dimensional accuracy. Common sizes are held in stock to support immediate supply, while specialised dimensions are produced to operational requirement.

Blast hole liner production follows a tightly managed workflow. PVC is precision slit to the required width before entering a continuous hot wedge welding process, where the liner tube is formed and sealed in a single controlled operation.

This integrated fabrication approach minimises variability and maintains strict control over diameter, seam integrity and dimensional consistency — delivering repeatable production quality that supports reliable installation and predictable in-field performance.
