ParaGrid, ParaLink & Terram-Grid

Terram Grid, ParaGrid and ParaLink are polyester geogrids.


They have a composite structure consisting of an inner core of high tensile modulus, low creep polyester fibers, protected by a polyethylene sheath (ParaGrid & ParaLink) or a durable coating of PVC (Terram-Grid).


The main applications are in the field of reinforcement of embankments over soft soils, piles or spanning voids where long term design life is required.
