Geosynthetic Cementitious Composite Mats (GCCM’s) were originally developed in 2005 and are a relatively new material technology in the world of geosynthetics. GCCM’s consist of a flexible 3-dimensional fibre matrix filled with a high-early strength dry concrete mix with a PVC membrane laminated onto one side. In this way they combine geotextile, geomembrane and concrete technology enabling geosynthetics to be used in completely new markets and applications.
Geosynthetic Cementitious Composite Barriers (GCCB’s) were developed as an extension of the GCCM technology and largely driven in response to the more demanding rules and regulations imposed on petrochemical terminal operators over recent years. This paper is an overview of this innovative material technology, including details of key properties and how these can be fully utilised in application. It will demonstrate through case history, how GCCB’s have found their place in a crowded market and brought strong, tangible benefits to the various stakeholders tasked with managing petrochemical facilities on a day-to-day basis.
