SKU: HYD-21-1 Categories: ,

Product Description

The Ultimate Barrier for suppressing odors, vapors, and gases (methane, hydrogen sulfide, ammonia, etc.) emanating from the landfill surface. HydraGuard is a mixture of vinyl acetate and acrylic polymers blended so they will easily soak into a variety of soils. The objective is to get at least an inch of penetration. The liquid mixture will dry and harden creating a semi-impermeable layer that restricts stormwater penetration and similarly restricts the passage of gas, vapor, and VOC’s.

When applied to the surface of clay, it soaks into the clay. Full penetration is achieved when the surface takes on the look of a glazed donut as shown in the photo to the right of an aluminum dross monofil in Tennessee. HydraGuard was developed for this site to reduce its ammonia odors resulting from the penetration of water and its interaction with the aluminum dross. You can see a video of that site manager at


NWCI manufacturers other cover materials used in remediation projects that are sprayed on the surface of the contaminated soil and achieve the same objective as a traditional cover. HydraGuard is different because it soaks into the soil as opposed to sitting on the surface. Geomembranes and special fabric coatings require additional maintenance, and are affected by wind. spray on ‘above surface coatings’ can get washed out in areas because stormwater gets behind and under the coating. With HydraGuard this does not happen because the coating is the soil surface.

HydraGuards Spectrum of Landfill Solutions

Because of its unique characteristics, by varying the levels of dilution, HydraGuard can be used for Erosion Control on slopes, dust control on low and heavy trafficked areas, odor and VOC suppression, and minimization of stormwater penetration into the landfill.

How to Use the Chart:

The chart below is designed to help you see how the different dilutions of HydraGuard in water can be utilized for different
purposes, improving durability and capability, as you decrease the number of parts of water to one part HydraGuard. The chart can help you understand application rates as well, both in terms of gallons of HydraGuard mixed with water needed to cover an acre, or how many square feet a gallon of concentrate will cover
