Sealing strip composed of natural sodium bentonite (76%) and a specialized elastomeric binder (24%), giving it excellent plasticity and elasticity. It is specifically designed to seal horizontal and vertical cold joints in concrete structures, providing reliable waterproofing under both hydrostatic and non-hydrostatic conditions. The strip swells upon contact with water, forming a tight seal that prevents water infiltration and ensures long-term structural integrity.

• Width 20×25 mm.
• Weight 25 kg / 30 m.

• Sealing horizontal and vertical cold joints in cast-in-place concrete

• Protection against hydrostatic and non-hydrostatic water pressure

• Underground structures such as basements, tunnels, water tanks, and retaining walls

• Reinforcement of waterproofing in foundations and substructures

• Suitable for new concrete pours; not for precast concrete or retrofitting existing hardened concrete

• Self-sealing: Swells upon contact with water to fill gaps and cracks

• High elasticity and plasticity: Adapts to irregular joint surfaces

• Durable under extreme temperatures: -30°C to +80°C

• High expansion and pressure resistance: Generates >1500 kPa during swelling

• Easy to install: Requires minimal surface preparation and no special tools

• Environmentally safe: Made from natural bentonite with non-toxic binders

• Reliable for long-term waterproofing in underground concrete structures
