AquaBlok, Ltd., a manufacturer of innovative clay-based composite materials, is proud to announce the introduction of a new family of pond sealant materials that benefit from the company's patented delivery system for bentonite sealant materials.
AquaBlok® Pond Seal Products utilize the company's well-established technology for delivering bentonite sealant material though a water column to seal a range of leaking water bodies. The unique material design incorporates an aggregate core coated with bentonite to effectively place maintain a sealant layer.
As Pond Seal coated particles hydrate and swell, they coalesce to form a flexible but cohesive layer or liner on the bottom of a pond, reservoir, canal, levee, or dam to block off potential leakage pathways.
Many ponds, canals, reservoirs or waterways are constructed in porous or other permeable soils that can sometimes be difficult to seal with conventional pond construction techniques. In addition, sometimes compacted soil liners can fail due to freeze/thaw or other natural ground movement. Once it is determined that a water body is leaking, few options exist to create an effectively seal without first draining all water. In more mature ponds or reservoirs, this is often not a desirable option since complete destruction of the existing habitat will take place. Pure bentonite powder or granules are often promoted as a means to seal a pond by simply pouring the material though the water. However, most pond management professionals understand that this method is generally ineffective since only a fraction of the material placed actually makes it to the bottom and what little does is not adequately compacted in a manner that makes the bentonite seal a more effective seepage barrier.
Two important advantages are provided by AquaBlok's Pond Seal product. First, the dense aggregate core of the Pond Seal particle (greater mass) effectively delivers the bentonite though the water to bottom, where all of the sealant material can be effectively utilized. Second, the aggregate provides "self-compaction" (resistance for the hydrating and expanding bentonite), creating a more stable and erosion resistant layer that will remain in place for many years. In addition, Pond Seal can be re-applied in the event that additional leaks are discovered at a future point.
Other important features of AquaBlok Pond Seal include:
- Will Dry Out and Rehydrate an Infinite Number of Times if Water Levels Change
- Remains Pliable when Hydrated - Will not "liquefy" during Seismic Events
- Ability to "Re-Heal" if Punctured or Cut
