Petrochemical containment

Petrochemical geomembranes prefabrication

Off-site prefabrication of material is a distinct advantage but knowledge of its incorporation into the overall liner is required. Installation staff should be aware of material movement issues on site, and the need to protect the liner during its application phase. Where the material requires joints, these should be welded by installers qualified to the CSWIP TWI Plastic Welding Standard.

Importance of correct training

It is usually preferable for liner installation to be done by a supplier’s directly-employed technicians, to ensure single line responsibility throughout the duration of the project. A sub-contractor trained installation team is unlikely to have the necessary level of expertise required and will generally be working on a self employed basis. A manufacturer’s “tool-box talk” and a limited amount of welding practice is rarely sufficient to produce a suitable outcome.

Best practice points towards the material supplier’s in-house trained and qualified staff, secure, safe and guaranteed. Talk to PAGeo about the importance of correct geomembrane installation in a wide variety of applications.
