To make the IGS more responsive to local needs there are 14 country or regional chapters which cover over 80% of the membership.
The need for IGS and its chapters is driven by the need to condense the vast amount of information which is available on the wide range of geosynthetic products available.
It is the responsibility of the chapters, such as the UK section of the IGS, to organise local events such as evening meetings, special lectures from visiting specialists and national meetings and seminars of specific interest to the membership. In the UK many of the evening meetings are held in co-operation with local associations of ICE or local geotechnical groups.
'To those of us who work in this industry day after day it is obvious that a woven geotextile will have different performance characteristics from a knitted product and that a needle punched non-woven will be different from a spun-bonded,' says Paul. 'Similarly, staple fibre products are different from those made from continuous filaments. Multiplying these different constructions into geogrids, geonets and geomembranes all with various polymer types means that the specifier and user needs some guidance, hence IGS.'
