The Corriform Permanent Shuttering System
Groundwork Engineered Systems original core product, ‘The Corriform Permanent Shuttering System’, invented by W. Winter in 1997 has certainly made an impact to the UK method of forming concrete foundation shuttering.
W.W. has the feeling that although it’s increasing popularity for its labour and other cost saving attributes amongst the jobbing ground workers, its merits have not been truly understood, believing that its use is to loosely contain mass concrete.
It seems that they lack the trust in its ability to accurately form the element shape, as designed by the consulting engineer. Maybe this is also due to the lack of any clear site inspection or understanding of the Corriform system’s capability.
Nevertheless it has a value and perhaps in time, it will gain credence from the authorities, who will look on it with a more serious eye and perhaps understand that it certainly does have the capability to accurately form the concrete element as per design.
The system is mainly more accurate when fabricated in house and is able to form all manner of concrete element shapes, if installed correctly. The core material polypropylene can be easily fabricated to create many larger shapes as our project list above illustrates.
Many incredibly large concrete elements have been created. These include wind turbine bases, lift shaft bases and more! W.W. definitely feels that the usage of polypropylene (Corriform), is at present under achieving, as to what he feels the true usage should be if utilised correctly.
