Geosynthetic Cementitious Composite Mat (GCCM): a factory assembled geosynthetic composite consisting of a cementitious
layer contained within a layer or layers of geosynthetic materials
GCCM’s are flexible
concrete impregnated
fabrics that hardens
when hydrated to form
thin, durable waterproof
concrete layers

Geosynthetic Cementitious Composite Barrier (GCCB):
GCCB is an extension of GCCM technology
GCCB’s combine a
concrete impregnated
fabric technology with a low
permeability, chemically
resistant geomembrane
liner, which allows joints to
be thermally bonded for on-
site air channel testing.

Summary and conclusions
With an increasing awareness and greater focus placed on
environmental protection and the impact petrochemical assets
have on their surroundings, operators are continually challenged
with the use of traditional materials to ensure compliance and
safe operation.
We should consider new material technologies that can minimize
the contractor burden and provide maintenance free solutions
where available.
GCCM’s and GCCB’s are disruptive material technologies that are
having a dramatic impact on the industry, providing multiple
benefits to terminal operators all over the world.
