Anti-Seep Collar/Trench Dam/Trench breaker Collars_Trench Dams.JPGHistorically, “anti-seep collars” made of a variety of materials (rubber, PVC, plastics, and even concrete) have been installed with the intention of serving as an impermeable barrier that encircles a pipe below grade. While these collars often do prevent wash-out, installation can be time consuming and technically problematic. AquaBlok serves as an alternative.

Dam Construction & core trench design

clientuploads/applications/lister_thumbs/Dam-Berm-Levee Construction & Repair.jpgWhether called a core trench, cut-off wall, or containment curtain, the goal remains essentially the same – to create a vertically-oriented hydraulic barrier to prevent the lateral movement of water (and/or contaminant). As a pre-blended, pour-in-place backfill, AquaBlok is structurally superior to traditional alternatives and its simple installation saves money.

Well Sealing - HoleBlok & holeblok+ Sealing.jpgA low-permeability hydraulic seal is typically required for well decommissioning and during construction of monitoring and other types of wells for a variety of industry processes. The seal minimizes the potential for vertical transfer of water along the well’s annular space. The solids-rich composition of AquaBlok and HoleBlok (a clay-rich product line specifically formulated for drilling applications) aids in reliable material placement, reduces bridging, and results in a consistent and durable seal.

Foundation Protection

clientuploads/applications/lister_thumbs/Foundation Protection.jpgWater directly against a building’s foundation is rarely a good thing and no one likes a leaking basement. But options to address excess roof runoff and/or poor drainage away from a foundation can be limited once initial construction is completed. AquaBlok placed into a shallow trench along the perimeter of a building or as a sub-surface blanket around points of increased vulnerability (e.g. downspouts) can be a pennies on the dollar investment to prevent water damage.

Earthen Pond/Basin Leaks & Repairs Pond-Basin Rehabilitation.jpgLeaking pond? When on-site soils allow for water loss (seepage) to exceed water gain (input from precipitation/run-off), consistently low water levels result. AquaBlok offers two remedy options: (1) basin spot treatment to target isolated areas of vulnerability, and (2) full basin lining to reduce permeability over the majority of a waterway’s footprint.

Earthen Pond/Basin Lining

clientuploads/applications/lister_thumbs/Earthen Pond-Basin Construction.jpgMany basins are excavated into inconsistent or marginal soils that are not ideally suited to hold surface water. If on-site substrates cannot be relied upon to hold water on their own, AquaBlok offers both full basin and spot treatments to help ensure proper function from the onset.

Synthetic Liner Reinforcement & Repair

clientuploads/applications/lister_thumbs/Synthetic Liner Reinforcement & Repair.JPGCuts or tears in liner materials are a fact of life. Whether it is an incidental puncture from subsurface stone, damage from a rodent, deterioration from exposure to the sun’s ultraviolet light, or an intentional breach to install conduit for irrigation, spot-repair is a reality of the long-term maintenance of any synthetic liner material. AquaBlok is your trusted Band-Aid.

Plugging Animal Burrows

clientuploads/applications/lister_thumbs/Plugging Animal Burrows.jpgBurrowing animals present an ongoing management challenge. Degradation to dikes, berms, and shorelines of valuable water resources from animals such as muskrats, nutria, groundhogs, and beaver can lead to leaks that may start small but worsen with time. Great for the do-it-yourselfer and equally valuable for the professional manager, AquaBlok offers a simpler fix.

Structure Bedding (Installation Phase) Bedding.jpgAny physical structure (e.g. stormwater overflow, catch basin, hydrant, etc.) installed to store or convey water is a source of vulnerability. Poor soils, inadequate compaction, erosional forces over time, or a combination of these factors can lead to failures – compromising the function of the structure and/or broader soil stability. AquaBlok is inexpensive insurance.


Manhole Sealing (Infiltration Reduction) Sealing.jpgMany stressors invite unwanted, clean water to enter a sanitary system or other underground utility that conveys liquids that must be treated. Joints, stubs, and risers are particularly vulnerable to ground/surface water seepage. Deterioration from age and physical abuse (e.g. freeze/thaw, street traffic) only compounds the chances of costly leaks. AquaBlok yet again serves as a simple, pour-in-place exterior seal that is both flexible & durable.


Streambed/Canal/Ditch Lining Lining.jpgJust as with basins (e.g. ponds), moving bodies of water can experience water loss through bottom substrates, the side slopes, or both. This seepage becomes problematic most often when adjacent land use activities (e.g. mining) or seismic activity disturbs the geology of the underlying channel bed. The labor savings in reduced material handling along with the improved consistency of the seal can be significant in these installations.


Temporary Dams/Stream Diversions Dam.JPGWhether in conjunction with another physical barrier (e.g. as a bedding beneath a “bladder dam”) or as a stand-alone quick-fix within a short-term earthen dam or diversion, this is a classic example of AquaBlok doing what its name suggests. Moving water will flow through the individual particles as they hydrate, but in a matter of hours a consistent seal will form. Removal/disposal is as simple as a well placed excavator bucket.


Flood Mitigation Mitigation.JPGThe word “AquaBlok” can’t mean more than it does when your home, facility, or entire community is threatened by rising flood waters. Used in conjunction with traditional protection (e.g. sandbags, gabions, etc.), AquaBlok offers a consistently reliable seal at vulnerable transition points (e.g. between and beneath sandbag barrier walls), particularly when bracing to shield critical structures from water damage.


Slope Sealing/Stabilization (Cellular Confinement) Sealing.jpgAquaBlok placed into a three-dimensional cellular confinement system or geocell provides a classic example of multiple innovative products being utilized together to broaden the capabilities that each could offer individually. Most complementary on grades steeper than 3:1, this combination can be relevant on stream banks and shorelines or in any situation where surface water must be managed over severe topography (e.g. roadways, mining facilities, etc.).


Sink Hole Repair

clientuploads/applications/lister_thumbs/Sink Hole Repair.jpgBecause no two sink holes are the same, no two sink hole repairs are identical. That said, many surface depressions – whether caused by karst processes or general soil instability – benefit from a low-permeable sealant layer within the framework of a broader stability design. AquaBlok placed atop a newly re-established aggregate base can offer extra insurance to dramatically reduce the movement of water and help prevent the migration and reoccurrence of a repeat sink.


Landfill Patch Patch.jpgPerhaps one of the most powerful attributes of AquaBlok is its ability to accomplish in inches what it would traditionally take feet of compacted clay to achieve. This benefit is realized in many different situations when maintaining a certified cap on a landfill or other waste disposal facility. When consistent and extremely low permeability (10-7 cm/s or lower) along with long-term durability (e.g. resilience to desiccation cracking and freeze/thaw damage) are a must, AquaBlok truly shines.


Gas Migration Barrier Migration Barrier.jpgAquaBlok doesn’t just contain water. When applied below grade in a setting that will remain saturated, it also serves to fortify utilities that convey gases (e.g. methane collection systems on landfills). The structural support of the aggregate core coupled with the sealing capacity of the high quality sodium bentonite makes AquaBlok ideal both for bedding pipe and for reinforcing critical joints and junctions.


To Be Determined Mark.jpgAs this page begins to attest, one of the unique attributes of AquaBlok is its versatility. Since its invention as a low-permeable sediment cap, engineers, contractors, professional facility managers, and even homeowners have found new ways to use the “natural material that doesn’t naturally occur in nature.” Let us know if you come up with a new application.


Saving the Earth is good . . . but it’s not that good! It is not a silver bullet that will remedy all ills. There are still plenty of instances where traditional materials and methods (e.g. compacted clay, synthetic liners, ordinary bentonite, liquid slurries/grouts, etc.) make sense. Through some hands-on experience though, we hope you’ll find AquaBlok to be a helpful tool in the toolbox.
