SamiGrid®

SamiGrid is a composite product consisting of an asphalt reinforcement grid made from high modulus polyvinyl alcohol (PVA) fibres in combination with a non-woven fabric.

Saturation of the non-woven with bitumen means that SamiGrid also performs a sealing and stress alleviating membrane interlayer function to complement the reinforcing action of the grid. This combination of materials results in a high-performance product that is ideal for the rehabilitation of concrete and stabilised pavements by using an asphalt overlay. Through the active retardation of reflective cracking, SamiGrid significantly extends the service life of asphalt resurfaced concrete and stabilised pavements.
