Patent ID: 8882396

Claim:
A method of consolidating foundation soils and/or building sites in general, including the steps of: measuring the electrical resistivity in one or more volumes of the soil to be consolidated to determine the volume(s) of soil to be consolidated; making one or more holes in the soil as far as or towards the volume(s) to be consolidated; injecting an expanding resin into the hole(s) in the soil in order to perform a consolidation treatment; geoelectric monitoring of the injections by progressive measurement of the percentage variations Δρ(%) of mean electrical resistivity of the volume(s) of soil to be consolidated between a state N of the treatment and the immediately preceding state N−1; and interrupting the injections into a particular volume of the soil to be consolidated when the differences in the percentage variations of electrical resistivity [ ( ρ N - ρ 0 ρ 0 ) · 100 ⁢ ( % ) ] ⁢ ⁢ and ⁢ [ ( ρ N - 1 - ρ 0 ρ 0 ) · 100 ⁢ ( % ) ] measured during the course of work in the soil, between the last state reached N and the immediately preceding state N−1, respectively, satisfy the following equation:  ( ρ N - ρ 0 ρ 0 - ρ N - 1 - ρ 0 ρ 0 ) · 100 ⁢ ( % )  ≤ 5 ⁢ % .
