BENTPRO® SEAL is a natural sodium bentonite with high swelling properties which makes it ideal for use in Geo Synthetic Clayliners. As the clay hydrates it swells, giving it the ability to “selfheal” holes in the GCL. BENTPRO® SEAL is also a low-dust and popular choice for hydraulic barrier applications like soil and geo-structure sealing, landfill liners, caps and sewer lagoon liners.

BENTPRO® SEAL is an environmental grade bentonite and is available in granules as well as powder form.
