BentoShield Max 7 – High-Pressure Waterproofing
Bentoshield MAX 7
BentoShield Max 7 is a geosynthetic clay liner produced by sandwiching natural sodium bentonite granules between two layers of polypropylene geotextile and bonding them via needle-punching. Upon contact with water, the bentonite layer swells to form an effective hydraulic barrier with low permeability to liquids, water vapor, and gases.
Developed for foundation and retaining wall waterproofing applications, BentoShield Max 7 is suitable for use under normal environmental conditions and in projects subject to low hydrostatic pressure. Thanks to its composition, which allows for direct application onto compacted soil, it limits water migration into structural elements and supports long-term waterproofing performance.
Its high bentonite content and durable geocomposite structure help maintain system integrity against punctures and mechanical impacts during installation. By forming a mechanical bond with the concrete, it restricts water migration between the waterproofing layer and the structure, offering an economical, active, and reliable waterproofing solution for foundation and retaining wall applications.
BentoShield Max 7 – High-Pressure Waterproofing Functions
BentoShield Max 7 is a bentonite-based waterproofing system that swells upon contact with water to form an active hydraulic barrier. While limiting water ingress into structural elements in foundation and curtain wall applications, its durable geocomposite structure supports long-lasting and reliable waterproofing performance against hydrostatic pressure.
High-Pressure Insulation
Thanks to its high bentonite content, it provides reliable waterproofing for foundation, retaining wall, and deep excavation applications subject to hydrostatic pressure.
Active Hydraulic Barrier
Upon contact with water, bentonite swells to form an active, low-permeability barrier, limiting the passage of water to the structural elements.
Foundation and Shear Wall Protection
It contributes to protecting the structure against the effects of water and moisture by forming a continuous insulation layer on foundation and reinforced concrete shear wall surfaces.
An economical solution developed for deep foundations
BentoShield Max 7 is a geosynthetic waterproofing material containing a high concentration of natural sodium bentonite, developed for deep foundation applications under normal environmental conditions. Upon contact with water, it undergoes hydration and swells, forming an effective hydraulic barrier with low permeability to liquids, water vapor, and gases.
Bentoshield Max 7 Features
- Bentoshield Max 7 can be nailed to concrete wall surfaces.
- Bentoshield Max 7 does not require grout and can be applied directly onto compacted ground.
- Due to its high resistance to punctures, there is no need for a protective cap.
- Bentoshield Max 7 mechanically bonds with concrete, preventing water from passing between the water itself and the structure.
- It is not applied to protective geotextiles and protection boards in foundation and curtain wall construction.
- Bentoshield Max 7 saves both money and time by reducing the volume of excavation, as it eliminates the need for blinding concrete and a protective screed.
- It is manufactured in widths of up to 6 meters, offering cost savings by reducing the number of overlaps required.
Frequently Asked Questions
What is BentoShield Max 7?
BentoShield Max 7 is a geosynthetic waterproofing material containing a high amount of sodium bentonite and developed for use in deep foundation applications.
In which areas is BentoShield Max 7 used?
It can be used for deep foundation and reinforced concrete shear wall waterproofing applications under normal environmental conditions. Suitability for the project must be evaluated based on soil conditions, water pressure, and technical specifications.
How does BentoShield Max 7 provide waterproofing?
When the sodium bentonite layer comes into contact with water and undergoes hydration, it swells and forms a low-permeability hydraulic barrier against liquids, water vapor, and gases.
Does BentoShield Max 7 form a mechanical bond with concrete?
Yes. By forming a mechanical bond with the concrete, it helps limit the movement of water between the concrete and the waterproofing layer.
Can BentoShield Max 7 be applied over compacted soil?
It can be applied directly onto compacted ground following appropriate surface preparation. The manufacturer states that the product can be applied without the use of blinding concrete.
What should be considered during the application of BentoShield Max 7?
The application surface must be prepared, and details regarding overlaps, fastening, and joints must be executed in accordance with the technical specifications. The suitability of the product regarding water pressure and foundation depth must be determined based on project calculations and the current technical data sheet.
