SamiGrid is a composite product consisting of an asphalt reinforcement grid made from high-modulus polyvinyl alcohol (PVA) fibres in combination with a nonwoven fabric. Saturation of the nonwoven with bitumen means that SamiGrid also performs a sealing function to complement the reinforcing action of the grid. This powerful combination of materials results in a high-performance product that is ideal for the rehabilitation of concrete pavements by using an asphalt overlay. Through the active retardation of reflective cracking, SamiGrid significantly extends the service life of asphalt resurfaced concrete pavements.

Sustainability Outcomes

Unlike other raw materials, PVA exhibits a high resistance to alkaline environments. This makes it ideal for the rehabilitation of concrete pavements. SamiGrid is also suitable for the reinstatement of concrete surfaces damaged by alkali-silica reaction due to the particular benefits offered by its sealing function. Given its high resistance to mechanical damage during installation, SamiGrid can also be laid directly onto milled surfaces. SamiGrid provides the possibility to rehabilitate concrete pavements without the need to demolish and then landfill.

Studies confirm significant CO2 reduction through geosynthetics. Geosynthetics are high-quality and durable synthetic materials whose sustainability is proven.
The 2010 study “Sustainable Geosystems in Civil Engineering Applications” (WRAP) impressively demonstrates the significant savings potential in the use of geosynthetics on the basis of individual case studies. Compared to conventional construction methods, up to 89% CO2 emissions may be saved.

Innovative geotextiles can thus make a resource-efficient contribution to permanently reducing CO2 emissions in the construction industry.
