  • Patent number: 7850401
    Abstract: A method of applying polyacrylamide (PAM) for stabilizing soil particles of a land area from movement about the land area. The slope of the surface of the soil is measured, and a tentative application rate is determined based upon the slope of the land area. The stability of the soil of the land area is determined by placing a sample of the soil in a tray and pouring a liquid over the sample and evaluating the erosion potential of the soil by measuring any movement of the soil in the liquid. The liquid may be water or a mixture of water and PAM. The application rate may be increased above the tentative application rate if the soil sample showed a relatively higher vulnerability to erosion. An application rate is calculated for applying a mixture of PAM and water to the land area. The mixture is misted onto the surface of the land area in one or more mixture applications. An application of the mixture is continued until the top surface of the soil of the land area becomes saturated.

  • Patent number: 7438500
    Abstract: The invention relates to a barrier cap material including a blend of: a plurality of aggregate particles, and a plurality of manufactured composite particles including a hydratable sealant material. In a particular embodiment, the segregation of a blend of aggregate particles and composite particles, when dropped through a water column can be controlled by varying blends of aggregate and composite particles. In another embodiment, the permeability of the barrier cap material, when hydrated on a surface, can be controlled from 1×10?3 cm/sec to 1×10?8 cm/sec by varying blends of aggregate and composite particles.

  • Patent number: 7357602
    Abstract: A reinforcing device for earthworks comprises at least one reinforcing base element (3) from which extend a front wall (9) and a containment wall (15) which are spaced from each other to delimit, in an operative configuration in which they are erected with respect to the reinforcing base element (3), a facing region which is to be filled with filling material, such as stones or the like. The device also comprises bracket means (23) which can be coupled, in use, to the front wall (9) and to the containment wall (15). It is also possible to produce a second front wall which extends from the reinforcing base element (3) on the side opposite the first. A method for the production of a reinforced earthwork provides for laying on the ground a device of the type indicated.

  • Patent number: 7288581
    Abstract: The invention relates to a process for the stabilization of dusting surfaces characterized in that the dusty ground is tilled or scarified and mixed with polymers in form of water-redispersible polymer powders, which are optionally reemulsifiably modified, or reemulsifiable modified aqueous polymer dispersions, which are optionally sprayed on to the untreated dusty ground. In a preferred embodiment the redispersible polymer powder, respectively the reemulsifiable modified redispersible polymer powder or the reemulsifiable modified aqueous polymer dispersion, is combined with hydraulically setting compounds, preferably cement and/or gypsum.

  • Patent number: 7028774
    Abstract: The present invention provides methods of reducing the production of both water and particulates from subterranean formations; the methods are particularly useful in conjunction with subterranean formations surrounding wellbores and fractures. The methods comprise the steps of applying to a subterranean formation a pre-flush fluid, applying aqueous surfactant fluid, applying a low-viscosity consolidating fluid, and applying an after-flush fluid.
