Process for producing an acid-resistant barrier seal in soil, and concrete usable for this purpose Inventors: Francis Marcel Louis DELMAS Michel Auguste Georges GANDAIS ABSTRACT The invention relates to civil engineering. It relates to a process for producing a barrier seal in the soil which must be in contact with an acidic water which has a pH below 5.5, according to which a trench is excavated in the soil and the trench produced is filled with a sealing concrete comprising water, a clay and an acid-resistant granulate with self-filtering properties, wherein the sealing concrete additionally contains an aqueous solution of sodium and/or potassium silicate and is devoid of any acidic or acid-generating matter liable to form a silicic acid gel with the sili- cate, the proportion of sodium and/or potassium silicate incorporated in the sealing concrete being sufficient to give rise to the formation of a leakproof local barrier when the sealing wall is locally subjected to the per- colation of acid water originating from the surrounding soil. Application to fight against pollution.
