We recommend a thin layer of sand around the shoreline post-application to prevent tracking by people or animals. Once wet, this material becomes very slick and turns into a slime that does not quickly dissipate.

Soilfloc® Pond Sealant uses a two-part polymer system designed to locate and seal leaks naturally by working with the movement of water.

Step 1 – Flocculation (Part A):

Part A is a linear anionic polymer that carries a negative charge. When applied to the water’s surface, it attracts positively charged suspended clay and fine soil particles in the water column. As it binds with these particles, it becomes heavier and sinks to the bottom. Because water is actively moving toward the leak, Part A follows the flow into cracks, seams, and porous soil areas.

Step 2 – Swelling & Expansion:

Once inside the leak pathways, Part A hydrates and swells up to 300 times its weight. This expansion begins clogging soil pores and small fissures immediately.

Step 3 – Reinforcement (Part B):

Part B is a cross-linked polymer that continues to expand more slowly over several days. It absorbs water, enlarges within cracks and crevices, and reinforces the seal created by Part A.

Step 4 – Soil Matrix Seal:

Together, the linear and cross-linked polymers bind soil particles, plug void spaces, and create a flexible, long-lasting seal within the pond’s soil matrix — stopping water loss at the source.

Because the polymers are drawn directly toward active seepage, Soilfloc works best when the pond is full and leaking, allowing hydrostatic pressure to carry the material exactly where it is needed.
