  • Patent number: 5059251
    Abstract: Impermeabilization and/or consolidation product for soils and building materials, usable by injection, characterized by the fact that it is obtained by mixture of a compound of slag in suspension in water and of a silica liquor having a ratio of SiO.sub.2 Na.sub.2 O lower than 2 and a silica content greater than about 10% by weight.

  • Patent number: 5017233
    Abstract: The invention relates to a method of rendering a soil or another material like a mortar, a binder, or a concrete impervious by injecting it with a silica solution. A finely ground powdered compound containing calcium with a solubility in water of between approximately 0.01 g/l and approximately 2 g/l is mixed into the silica solution, which has a ratio of SiO.sub.2 to Na.sub.2 O of between 1 and 1.3, before injection.
    Type: Grant

  • Patent number: 4834579
    Abstract: A dam formed of roll-compacted concrete having an upstream side and a downstream side is provided with an impermeable membrane curtain. The curtain includes a vertical planar wall portion extending for the full depth of the dam and transversely for the full width of the dam. A series of vertical ribs are connected to and spaced transversely along the curtain. The ribs project toward the upstream side of the dam and extend for the full depth of the dam.

  • Patent number: 4615643
    Abstract: A method for sealing a mass of stored waste containing cations comprises insulating the waste mass with at least one grout barrier which retains heavy metallic cations. The grout barrier is established by filling the hollows in the soil or fissured rocks with a grout containing specified amounts of cement, clay, siliceous products, sodium carbonate and alkali-metal tartarate.

  • Patent number: 4514228
    Abstract: A composition for making impermeable walls and other underground structures comprising water, a cement, a silica compound in a dispersed form, and an activating agent selected from the group consisting of an alkaline base and an alkaline salt of a weak acid which do not contain silica, the ratio by weight of lime to silica being less than 1 and preferably between approximately 0.3 to 0.5.

  • Patent number: 3939664
    Abstract: A large diameter tubular pile for bedding into a borehole has an auxiliary tube extending inside it and a series of axially spaced apart holes through its wall which communicate with the interior of the auxiliary tube through discharge pipes which are arranged to allow flow only from the auxiliary tube to outside the pile. The pile is bedded in a borehole by first inserting the pile and then introducing into the auxiliary tube an injection pipe having a pair of axially spaced apart plugs which seal against the inner wall of the auxiliary tube. The injection pipe is located so that the plugs seal on opposite sides of an opening into a discharge pipe, and grout under pressure is forced from the injection pipe through the discharge pipe into the borehole around the pile. This procedure may be repeated for the other discharge pipes.
