Abstract: The present invention provides containment liners to protect the environment from spills and leaks at oil and/or gas production sites and other sites. The containment liner comprises a first felt geotextile layer and a polymeric barrier layer embedded partially into the felt geotextile layer.

Abstract: Self-raising drive-over entranceways for containment berms are disclosed. The entranceway includes a horizontal bottom panel and a collapsible sidewall that is held in a partially collapsed position forming a void between the bottom panel and sidewall. During a spill or the filling of the containment berm with a fluid, the void area between the partially collapsed sidewall and the horizontal bottom panel fills with the fluid and exerts hydrostatic pressure against the partially collapsed sidewall, forcing it to rotate upward. The higher the fluid level, the more hydrostatic pressure is applied against the sidewall, forcing it up higher until the sidewall obtains a vertical orientation. The sidewall may be restrained either by straps, braces or the like to prevent the fluid from escaping the containment area.

Abstract: Absorbent containment mats are disclosed. The mats include an upper absorbent layer, a lower liquid impermeable barrier layer, and a peripheral containment edge. The peripheral containment edge may have a lower profile than the absorbent layer. A pressure sensitive adhesive may be applied to the underside of the barrier layer. A durable porous layer may be provided over the absorbent layer.

Abstract: A moppable floor mat is disclosed comprising a plurality of layers sharing a common peripheral boundary, the layers including an adhesive layer, a liquid impermeable layer, a high-traction layer, and a liquid absorbent layer. The adhesive layer is configured to be releasably adhered to a floor and capable of being mopped over without causing a movement of the moppable floor mat relative to a surface of the floor. The moppable floor mat further comprises a seal formed adjacent the peripheral boundary of the plurality of layers, wherein the seal is configured to form a fluid-tight barrier preventing liquids from exiting through the seal from the moppable floor mat.

Abstract: A bladder-containing wall assembly for use in containment berms is disclosed. A bladder contained in the wall assembly communicates with the interior area of the containment berm via one or more inlet ports. The bladder self-deploys from the wall upon a substantial spill or leak inside the containment berm in order to increase the fluid containment volume of the containment device. The bladder-containing wall assembly may be substituted for a wall section of either permanent or portable containment berms.

Abstract: A leak diverter includes a liquid collection tray structured and arranged to be positioned below and supported by a suspended ceiling; a drain in flow communication with the liquid collection tray; and a plurality of magnetic suspension assemblies connected to the liquid collection tray, the magnetic suspension assemblies being structured and arranged to magnetically couple the leak diverter to a support frame in the suspended ceiling.

Abstract: Shapable protective covers for vertical drains and other holes to prevent spills and other liquids from flowing therein are disclosed. The shapable protective covers include a backing layer with a malleable shapable core and a pliable, tacky sealing layer. The pliable, tacky sealing layer may be secured to the other layers by a bonding layer adhered to or partially embedded in at least one of the layers. The shapable protective covers may be positioned over a vertical drain such that an exposed surface of a pliable, tacky sealing layer contacts a portion of the surface surrounding the vertical drain, thereby preventing liquids from passing through the drain.

Abstract: A drum band assembly for securing a lid to a drum. The drum band assembly includes a band having a first free end and a second free end and an attachment device connected to the band, wherein the attachment device is adapted for removably attaching the band to the drum. The drum band assembly further includes a lid mounting device attached to the lid and the band, wherein the lid mounting device is adapted to allow the lid to open and close on the drum.

Abstract: Berms for use with protective liners are disclosed. The berms may be configured to allow vehicular traffic to pass over the berms without causing damage. Such drive-over berms may be rigid and shaped to allow vehicle tires to pass over them, or may be resilient and collapsible such that they collapse when subjected to the weight of a vehicle tire, and then spring back to shape after the vehicle passes. Also disclosed are berms that may be stacked for storage and transportation purposes, and berms that include connectors for connecting multiple sections of the berms end-to-end.

Abstract: The present invention provides containment liners to protect the environment from spills and leaks at oil and/or gas production sites and other sites. The containment liner comprises a first felt geotextile layer and a polymeric barrier layer embedded partially into the felt geotextile layer.

Abstract: A repositionable fluid suction device is disclosed. The device includes a central body and a suction channel located on an underside of the central body extending at least partially around a periphery of the central body. A rim extends downward from the central body, and may define a portion of the suction channel. A fluid collection trough extends at least partially around the periphery of the central body to collect fluids that fall on the upper surface of the central body. The outermost peripheral edge of the suction device may comprise at least one concave portion extending radially inward toward the central body.

Abstract: A protective cover for drains and other holes is provided which prevents spills and unwanted liquids from flowing therein. The protective cover includes a durable backing layer and a pliable, tacky sealing layer adjacent a portion of the durable backing layer which conforms and adheres to a surface surrounding the drain to reduce or eliminate the flow of liquids into the drain. The pliable, tacky sealing layer can have a periphery inside the periphery of the durable backing layer.

Abstract: A containment bag having a base, a sidewall, and a lifting strap. The sidewall extends upward from the base and may include a sleeve top portion attached to or formed at an upper end of the sidewall opposite the base end. The sidewall or the sleeve top defines a bag opening. The lifting strap is attached to at least one of the sidewall and/or the sleeve top for lifting the containment bag. The containment bag may further comprise means for closing the bag opening. In addition, the containment bag may also include a disposable bag liner positionable within an interior of the sidewall.

Abstract: An absorbent structure is provided which comprises a first outer layer, a second outer layer, a core layer positioned between the first outer layer and the second outer layer, wherein the core layer comprises a recycled cellulose material, and a core bonding agent.

Abstract: Durable protective covers for drains and other holes are provided which prevent spills and unwanted liquids from flowing therein. The protective covers include a durable backing layer and a pliable, tacky sealing layer which conforms and adheres to a surface surrounding the drain to reduce or eliminate the flow of liquids into the drain. A low-density bonding layer is provided between the pliable, tacky sealing layer and the durable backing layer in order to provide significantly improved adherence between the layers.

Abstract: A device for damming and diverting liquid on a spill surface has an elongated, pliable dike having a first end, a second end and an exposed surface. The exposed surface is inherently tacky so that it is adherable to the spill surface to prevent flow of liquid past the dike. The dike is preferably made from a substance, such as polyurethane, that is inherently tacky. The device provides improved tear resistance by one or more additions to the construction of the device. Some of the additions to the construction also improve UV resistance and/or chemical compatibility. A method for creating a liquid control zone on a spill surface utilizing the dike of the present invention is also disclosed.

Abstract: The invention includes an absorbent mat including an absorbent layer having a first surface and an opposing second surface and an adhesive layer on at least a portion of the first surface of the absorbent layer. The opposing second surface is structured and arranged such that the adhesive layer is releasably adhereable with the second surface.
