✅ What Is Bentonite Duct Sealing?
Bentonite is a natural clay that swells when in contact with water, forming a watertight barrier. It is commonly used in electrical duct sealing, telecom manhole entries, and underground conduit systems to seal annular gaps between the conduit and surrounding concrete or earth.
This prevents:
– Water leaks into electrical manholes or vaults
– Sand migration and duct blockages
– Corrosion of underground cabling
