When a New Zealand lining company sought plastic welding training for its staff
it was determined to secure the best tuition available – even if it meant flying
an expert halfway around the world.
IS Dam Lining is New Zealand’s leading installer of geomembrane liners for liquid
containment and other applications. From its base in Hawke’s Bay, North Island,
the family-owned company installs waste water projects, HDPE containment dams and
irrigation and frost protection dams, both in New Zealand and overseas.
Much of the work IS Dam Lining carries out involves joining sections of plastic
lining to serve as an impermeable base for dams and ponds. Achieving a watertight
seal with high-integrity joints is paramount, so ensuring its technicians are proficient
plastic welders is critical to the business.
TWI is one of just a small number of organisations in the world with the expertise
to provide training in geomembrane welding, and the only one whose training leads
to internationally recognised CSWIP certification. Recognising the value of getting
its technicians qualified, IS Dam Lining contacted TWI to arrange a visit.
The company’s operations manager, Andrew Taylor, made the call. ‘CSWIP certification
is the only internationally recognised training scheme,’ he explains, ‘and will
ensure quality installations are undertaken by IS Dam Lining in New Zealand.’
Despite the considerable distance between TWI’s UK base and IS Dam Lining’s premises,
the company arranged for senior plastics welding trainer Andy Knight to undertake
the 11,000-mile journey. ‘We felt it was well worth the expense of flying Andy out,’
says Andrew, ‘to ensure our boys are all top notch.’
Once onsite, Andy delivered a course covering every aspect of geomembrane welding
including the main material types used, the methods used to join each one, equipment
calibration, inspection and testing, good and bad working practices and how to avoid
The training allowed the IS Dam Lining staff to attain CSWIP certification in plastic
welding, in accordance with European standard BS EN 13067. They were left with a
solid understanding of the welding process and in a strong position to maintain
IS Dam Lining’s reputation as New Zealand’s premier geomembrane lining provider.
