Modern nondestructive techniques of wave analysis can be applied for the preliminary geotechnical soil express assessment. The paper provides two practical step-by-step guidelines for an express assessment of the deformation modulus E and a model deformation curve of dispersive soils plotting based on the in-situ Multichannel Analysis of Surface Waves (MASW) testing. They were formulated based on the previous experimental, analytical and numerical studies, such as in-situ plate load tests (PLT) and MASW, laboratory triaxial tests, analytical studies and numerical PLT. The guidelines are applicable for normally compacted non-cohesive (sand) and cohesive mineral dispersive soils of any moisture content and undisturbed structure with a unit weight of 16.0–20.8 kN/m3, which are located in the Urals and Western Siberia at the depth of up to 6.5 m. For the deformation modulus estimation during preliminary geotechnical calculations, MASW allows labor intensity reduction up to 3 times and cost - up to 8 times as compared to conventional tests.
