Pond Sealing Bentonite

Bentonite is a type of clay that is known for its ability to absorb large amounts of water and swell in volume. Because of these properties, bentonite can be used as a pond sealant to prevent water seepage through the soil.

When bentonite is mixed with water, it forms a slurry or gel-like substance that can be spread over the surface of the pond or applied to the soil beneath it.The bentonite particles in the slurry are negatively charged and will attract positively charged ions in the soil, causing the particles to bond together and create a waterproof seal.

Before applying bentonite, it is important to analyze the soil to determine its composition and properties. Soil that is high in clay content may not require as much bentonite, whereas soil with a lot of sand or gravel may need more.The recommended application rate of bentonite for pond sealing is typically between 2 to 6 pounds per square foot, depending on the soil type and the desired level of sealing.


  • Bentonite is an effective pond sealant that can prevent water seepage through the soil. It forms a waterproof seal when hydrated, which can help to retain water levels in the pond.
  • Bentonite is a natural, non-toxic alternative to chemical sealants that may harm aquatic life which is relatively inexpensive and easy to apply.
  • Bentonite can be used to seal a variety of pond sizes and shapes, as well as other water bodies such as canals and reservoirs.
  • The use of bentonite as a pond sealant can help to prevent erosion and sedimentation, which can have negative impacts on water quality and aquatic habitats.
  • Bentonite is a long-lasting solution that can provide years of protection against water seepage and loss.
