Overview
Product Overview
KORVANTO BENTO SEAL™ is a premium-grade natural sodium bentonite specially developed for pond sealing water containment and seepage control applications. Owing to its exceptional swelling and water absorption properties the bentonite expands upon hydration to form a dense low-permeability barrier that effectively minimizes water loss through soil.
When mixed with suitable soils KORVANTO BENTO SEAL™ creates a durable and self-healing seal that helps retain water in ponds reservoirs lagoons canals and other water containment structures. Its natural rehydration and re-swelling characteristics enable long-term performance making it an economical and environmentally friendly alternative to synthetic liners.
Suitable for both new construction and leak remediation projects KORVANTO BENTO SEAL™ provides reliable water retention while preserving the natural characteristics of the site.
