Many waterways, independent of size and function, are constructed in porous or permeable soils that are not adequately compacted or amended during construction to reliably hold water. Even when soil basins or synthetic "liners" are properly prepared from the onset, a variety of environmental factors (e.g. repeated freeze/thaw cycles, prolonged desiccation, pockets of more permeable soils, and even subtle seismic activity) can compromise an earthen basin, causing problems over time. Additionally, structural failures or oversights (e.g. a faulty overflow structure or a hydrologicly connected agriculture tile) can eventually cause noticeable water loss.

Once a water body is determined to be leaking, traditional techniques limit the remedy options. Many professionals advise that a basin must be completely drained to effectively repair a compromised seal. Beyond the substantial cost, this is often not a desirable option, particularly in more mature waterways (due to the tremendously disruptive impact such a disturbance has on fish communities and the overall ecology in the system).

PONDSEAL™ utilizes a solid aggregate (limestone) core to deliver naturally mined bentonite clay through a water column to any area where a leak is suspected. Due to the extreme low permeability, considerable weight, and robust swelling characteristics of this novel composite particle, each individual "pebble-like" unit swells into adjacent particles to produce a uniform and durable layer – stopping the leak at its source.
