| 20080304921 | MICRO-CLIMATE CRAWL SPACE SYSTEM - A micro-climate crawl space system having a means for keeping water from entering the crawl space, a means of expelling water that enters the crawl space, a means for keeping water vapor from entering the crawl space, a means of expelling water vapor from the crawl space, and a means for minimizing the deleterious impact of water that is present in the crawl space. The means of expelling water is a durable thermal insulating sealing apparatus, where the apparatus isolates the crawl space; and a supply of conditioned air that is typically drawn from an interior of the building, where the conditioned air is supplied at a rate sufficient to effect a slight positive pressure on the crawl space. | 12-11-2008 |
| 20090257830 | Foundation wall vapor barrier system - A foundation wall vapor barrier system comprising a wall vapor barrier extending vertically along an interior portion of a foundation wall to resist moisture transfer through the foundation wall. The wall vapor barrier includes a non-woven fibrous core layer, a moisture impervious solid top layer bonded to and completely covering a first side of the core layer, a moisture impervious solid bottom layer bonded to a second side of the core layer opposite the first side, and, an adhesion strip defined by an absence of the bottom layer along a portion of the second side exposing the core layer for receiving adhesive to secure the wall vapor barrier to the foundation wall. A fire retardant low-VOC compliant non-solvent adhesive is disposed in the adhesion strip mounting the core layer to the foundation wall without mechanical fasteners. | 10-15-2009 |
| 20090297280 | Shiftable Fluid Diversion Conduit - A fluid diversion conduit is provided for temporarily diverting a stream during pipeline construction activities. The conduit includes an offset section that is shiftable to adjust access to the streambed, for example to allow pipeline installation across the streambed. When construction activities are obstructed by the initial position of the offset segment, the offset segment may be shifted, for example by rotation to elevate the offset segment from the streambed. Further construction activities may proceed beneath the elevated section, and pipelayers can pass under it while carrying the pipe string into position. Flow through the conduit may be maintained by siphon hydraulics or by pumps when the offset segment is elevated. | 12-03-2009 |
| 20100266348 | MULTICOMPONENT COMPOSITION FOR FILLING AND/OR INJECTING CRACKS, FLAWS AND CAVITIES IN STRUCTURES OR EARTH AND ROCK FORMATIONS - A multicomponent composition for filling and/or grouting cracks, flaws, and cavities in structures or earth and stone formations, including: i) water; ii) cement; iii) an aqueous plastic dispersion; and iv) at least one monomer, which can be radically polymerized, or a polyisocyanate. A material is thus obtained as a sealant, which displays great adjustment capabilities of hardness and reaction time, in addition to its cost-effectiveness. Such a composition unifies positive properties of various materials as a sealant, such as expansion capacity and swelling capacity. | 10-21-2010 |
| 20100278594 | EROSION CONTROL SYSTEM - Improved erosion control systems are provided which, in some embodiments, may comprise large, porous aggregate stabilized with a continuous mesh and a polymeric binding agent. In some embodiments, an erosion control system may include an aggregate layer comprising porous aggregate having a particle size of at least 7.5 mm and containing no more than 5% by weight of smaller particles; a continuous mesh disposed at an upper surface of the aggregate layer; and a polymer adhesive affixing at least some aggregate particles to each other and affixing the mesh to some of the aggregate particles, wherein the polymer adhesive permanently binds the aggregate and mesh such that the system remains porous. The polymer may be applied in-situ after the mesh has been placed on the aggregate. | 11-04-2010 |
| 20110103899 | Process for grouting a curtain with polymer - A process for grouting a super-thin curtain with polymer, includes: forming a series of V-shaped injecting holes by direct pushing method using a special drilling tool along a dam or dike axis spacedly at a predetermined distance; and injecting a two-component polymer composition into each of the holes, wherein the mixed polymer material expends and coagulates under chemical reaction to form a series of super-thin curtain segments, and the curtain segments connect with each other end to end to form a continuous and impermeable polymer curtain. | 05-05-2011 |
| 20130202365 | MANUFACTURED COMPOSITE HAVING SYNTHETIC VEGETATION AND IMPERMEABLE GEOMEMBRANE, AND CAPPING SYSTEM USING SAME - A manufactured composite comprising synthetic turf and impermeable geomembrane is used in a single-layer capping system as the single layer to provide permanent, impermeable and functional aesthetic cover for land reclamation. During installation of composite pieces at a job site, an edge portion of a tufted section of a second composite piece is overlaid onto an edge untufted section of the first composite piece already laid and anchored over foundation soil to form a reinforced overlapping seam, through which the two composite pieces are physically and permanently joined together. As composite pieces are joined together, the continuity of synthetic grass and the continuity of impermeability are extended and realized over the entire site to form permanent, impermeable and functional aesthetic cover for land reclamation. | 08-08-2013 |
| 20140255108 | Liquid Containment System for Use With Load-Supporting Surfaces - System for containing liquid introduced onto a reusable load-supporting surface includes a plurality of interconnectable berm members configured to releasably sealingly engage the load-supporting surface to prevent leakage of liquid from the load-supporting surface around its perimeter without the use of any liners beneath the load-supporting surface. | 09-11-2014 |
| 20140314499 | COMPOSITION FOR CONTROLLING PRESENCE OF WATER ON AN OUTER SURFACE - The present invention has as its purpose a composition ( | 10-23-2014 |
