Geosynthetics are one of the materials widely used in civil engineering. The article presents the use of a non-contact deformation measurement method (digital image correlation method - DIC) in laboratory test of an orthogonal geogrid. In tests carried out using the tensile method, the distributions of displacements and strains were determined for the entire surface of the tested samples. Moreover, the principal values and principal directionsof the strain tensor were determined. The occurrence of local principal strain accumulations on the surface oftested sampleswas observed. The effectiveness of the use of the digital image correlation (DIC) method in deformation analysis was confirmed.
