he invention refers to an impermeable material, by means of which is retained the water, fit for ponds, lakes, lagoons and the like objects, into which waste are placed, the underneath soil needing to be protected from penetration of water or other liquid medium. The impermeable material is obtained of a homogenous plastics, containing macroparticles of fulling clay and liquid, at least part of which constitutes water. The material represents a pressed and/or laminated stratum joined with the base sheet.The process for the impermeable material manufacture includes mixing of the macroparticles of fulling clay and liquid, at least, part of which constitutes water up to the obtaining of the homogenous plastics, plastics formation in a continuous stratum by pressure and/or lamination or by other processes, with the help of which the continuous stratum is joined with the base sheet.The result consists in increasing the material impermeability.Claims: 15Fig.: 16 |
