20080298901 | Soil Consolidating Method and Composition Therefor - The invention relates to a soil consolidation process using a combination of calcifying bacteria and denitrifying bacteria. | 12-04-2008 |
20090324344 | BIOSEALING - The invention relates to a method to repair a leak in a geological structure or a construction comprising a geological material, comprising administering a liquid nutrient composition, comprising an energy source for anaerobic bacteria and a multivalent metal ion upstream of the leak allowing micro-organisms present in the structure or construction to ferment the energy source and to grow, thereby increasing biomass in and/or around the leak releasing mineral particles upstream of the leak allowing the mineral particles to migrate to the leak; and allowing the mineral particles to settle in the biomass. | 12-31-2009 |
20110318115 | CHEMICAL METHOD AND COMPOSITION FOR SOIL IMPROVEMENT - A composition for chemical soil improvement includes a synthetic fluid or base oil, a pour point depressant, polyisobutylene, and synthetic fibers, and various combinations thereof. | 12-29-2011 |
20120269584 | Method for Water Tightening of Water Bearing Zones and Stabilization of Sand in Underground Constructions - Method for water tightening of water bearing zones and stabilization of sand in underground constructions, by precipitation of at least one mineral, by introducing into the construction, at the least one aqueous solution of salts comprising Ca2+ ions and urea, and an urease. The urease may be plant based, and made by grounding the plant wherefrom the urease is based, adding water, and soaking at occasional stirring between 2 and 20 h at room temperature. Then the achieved solution is filtrated, and the filtrate is lyophilized. The urease may also be biotechnologically produced by bacteria in an aqueous solution, where after the achieved solution is filtrated, and the filtrate is lyophilized. | 10-25-2012 |
20120288335 | Soil Stabilization Composition and Methods for Use - A soil stabilization composition is provided. The soil stabilization composition includes sulfuric acid, citric acid, phosphoric acid, nonlyphenol90, and water. The soil stabilization composition is capable of changing the molecular charges of swelling clays to resist water absorption rather than to attract water due to the positive/negative charges related to them. This ionic exchange prevents the clay from swelling making the clay more stable to build on. | 11-15-2012 |
20140126966 | SOIL FIXATION, DUST SUPPRESSION AND WATER RETENTION - A method for at least temporarily retaining moisture in a soil-based substrate includes applying an acrylamide pyranose polymer to the soil-based substrate. | 05-08-2014 |
20140377013 | USE OF POLYAMINE AS ANTI-STICKING ADDITIVE - Method of use of at least one polyamine compound selected from the group consisting of diethylenetriamine: triethylenetetramine (TETA), tetraethylengentemine (TEPA). pentaethylenehexamine (PEHA), hexaethyieneheptamine and heptaethyleneoctamine sticking decreasing additive for soil with a day mineral content o more than 10% by weight. | 12-25-2014 |
20150056022 | SOIL HYDROPHILIZATION AGENT AND METHODS FOR USE - Disclosed are soil additives capable of hydrophilizing soil particles and/or increase available water capacity in soil. The soil additive are capable of increasing the available water content/capacity (AWC) in soils, the additive in one embodiment comprising a polymer composition having a hydrophilic portion and a hydrophobic portion, wherein the hydrophobic portion of the copolymer binds with the soil particle surface and the hydrophilic portion of the copolymer can bind with water. This results in the prevention, arrest or decelerated loss of water from the targeted area, for example the plant root zone, which allows for improved water usage efficiency by plants, grasses, vegetation, etc. | 02-26-2015 |
20150071713 | SURFACE TREATMENT COMPOSITIONS AND PREPARATION METHODS - Surface treatment compositions and their methods of preparation. Such surface treatment compositions can comprise a solid cross-linking agent and a water-soluble polymer. Such solid cross-linking agent can include a plurality of dialdehyde residues, and the water-soluble polymer can include a plurality of pendant groups capable of covalently bonding with the solid cross-linking agent. The surface treatment compositions can further comprise a fibrous material. Applications for such surface treatment compositions include soil erosion prevention, dust control, and landfill cover. | 03-12-2015 |
20150322339 | USE OF POLYAMINE AS ANTI-STICKING ADDITIVE - Method of use of at least one polyamine compound as sticking decreasing additive for soil with a clay content of more than 10% by weight. | 11-12-2015 |
20150353825 | METHOD FOR PREVENTING SOIL EROSION - Provided is a method for preventing soil erosion in which a nonionic guar and/or a cationic guar is applied on or into the soil. A method for preventing water runoff of a soil in which a nonionic guar and/or a cationic guar is applied on or into the soil is also provided. A treated soil against the soil erosion susceptible to be obtained by the method for preventing soil erosion in which a nonionic guar and/or a cationic guar is applied on or into the soil is also provided. | 12-10-2015 |
