HydraGuard is NWC’s propriety liquid formulation of polymers and other cross-linked chemistries that enhances the durability of the ConCover line of products as well as the ProGuard line of products. NWC’s HydraGuard liquid comes in a 275 gallon (1040 liter) plastic flexible tote. Cost per square foot ranges from 1-2 cents (USD) or 10.7 – 21.5 cents (USD) per square meter depending upon whether you topically apply the HydraGuard to the dried surface of the recently applied cover material or mix the HydraGuard with the initial product, the later process requires about twice the volume of liquid HydraGuard.
Topical Application of HydraGuard Using HydraGuard topically allows you to put a polymeric film over the surface of the cover product that will resist the penetration of water. It is similar to putting a finish varnish or clear coat of paint on the surface of wood. Typical mixing ratio of HydraGuard with Water, when topically applying the product, is to use 10-15% of the final solution as HydraGuard. Mix the product, and then lightly spray the combined mixture on the surface of the previously applied cover material.
Mixing HydraGuard with Cover Material HydraGuard can also be mixed with the cover material as it is being blended. We suggest that the HydraGuard be added when the water is put into the tank. With ConCover 180, we believe that you want to have 10% - 15% of the liquid volume as HydraGuard, depending upon the circumstances. One of the advantages of mixing it with the product is that you don’t have to come back and re-coat the surface which often requires application planning. With ConCover SW, the mixing ratio is about the same (i.e. 10% of the water should be HydraGuard). Apply the cover material in the same manner you normally would.

| Designed for use as: |
- As an additive for ConCover 180 and ConCover SW
- When added to ConCover 180, it creates an alternative to plastic scrim or seamed geotextile where the cost of putting down plastic or geotextiles can be 10-15 times more expensive.
- When added to ConCover 180 – provides a low cost, easily repaired method of reducing the volatilization of gases emanating from areas of temporary soil cover
- When added to ConCover 180 – can improve the gas impermeability of the ConCover 180 product, suppressing the amount of oxygen that can be sucked through the surface
- When added to ConCover SW – it can improve the ability of the ConCover SW to shed water on exterior slopes and for area where you want to control
